Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1(A) is a side view of a vehicle 1 equipped with a flare dropping device 100 according to an embodiment of the present invention, and FIG. 1(B) is a plan view of the vehicle 1 shown in FIG. 1(A). . As shown in FIGS. 1A and 1B, the vehicle 1 includes a loading platform 2, left and right side tilts 3a of the loading platform 2, and a rear tilting 3b of the loading platform 2. The flare dropping device 100 is installed on the loading platform 2.

The driver's cab 4 of the vehicle 1 is provided with a touch panel storage box 4a, a remote control box 4b, and a control panel 4c. In this embodiment, when the operator operates the touch panel storage box 4a and the remote control box 4b in the driver's cab 4, the flare dropping device 100 is driven, and the flare 9 is ignited and dropped onto the road surface.

FIG. 2 is a perspective view of the flare tube 9. As shown in FIG. 2, the flare tube 9 includes a rod-shaped body 9a, an ignition part 9b provided at one end of the body 9a, and a holder 9c that covers the other end of the body 9a. A rectangular flange 9d for preventing rolling is formed on the holder 9c. By applying heat to the ignition part 9b, the flare tube 9 is ignited. The end surface provided with the ignition portion 9b is also referred to as an "ignition surface 9e."

FIG. 3 is a plan view schematically showing the internal structure of the flare dropping device 100. In addition, in FIG. 3, illustration of the cover of the flare dropping device 100 is omitted. Actually, the flare dropping device 100 is equipped with a cover (not shown) so that the internal structure of the flare dropping device 100 cannot be seen.

As shown in FIG. 3, the flare dropping device 100 includes a housing section 10 that accommodates a plurality of flares 9. The housing section 10 is provided with a driving pulley 11 and a plurality of driven pulleys 12. A timing belt 13 is wound around the drive pulley 11 and the plurality of driven pulleys 12.

A large number of partitions 14 are arranged upright on the timing belt 13 at equal intervals, and a cartridge (not shown) is provided between the partitions 14 . A flare tube 9 is set in each cartridge.

When a motor (not shown) connected to the drive pulley 11 is driven, the drive pulley 11 rotates and the timing belt 13 moves in the direction of the arrow shown in FIG. As a result, the flare tube 9 is carried in the direction of movement of the timing belt 13.

In the example shown in FIG. 3, four driven pulleys 12 are provided, and the timing belt 13 is wound around the drive pulley 11 and the plurality of driven pulleys 12 in a U-shape. Therefore, the timing belt 13 can be made longer, and the number of flare tubes 9 that can be accommodated can be increased.

The flare dropping device 100 includes a gripping tool 20 that is movably provided with respect to the housing section 10 and a laser irradiation section 30 that irradiates the flare tube 9 held by the gripping tool 20 with a laser beam to ignite the flare tube 9. We are prepared. The gripping tool 20 grips the flare tubes 9 sequentially carried by the timing belt 13, takes out the flare tubes 9 from the storage section 10, releases the flare tubes 9, and drops them onto the road surface. The operation of the gripper 20 will be described in detail with reference to FIGS. 4 to 6.

FIG. 4 is a diagram showing the vicinity of the gripper 20 and the laser irradiation unit 30. FIG. 4(A) is a view (side view) of the gripping tool 20 and the laser irradiation unit 30 seen in the direction of the arrow IVA shown in FIG. 4(B) is a diagram (plan view) of the gripping tool 20 and the laser irradiation unit 30 seen in the direction of arrow IVB shown in FIG. 4(A), and FIG. FIG. 3 is a view (bottom view) of the gripping tool 20 and the laser irradiation unit 30 viewed in the direction of arrow IVC shown in FIG. FIG. 4(D) is a view (front view) of the gripping tool 20 and the laser irradiation unit 30 seen in the direction of arrow IVD shown in FIG. 4(A), and FIG. 4(E) is a diagram of FIG. FIG. 3 is a view (rear view) of the gripping tool 20 and the laser irradiation unit 30 seen in the direction of arrow IVE shown in FIG. In addition, in FIG. 4, illustration of the ignition part 9b and the flange body 9d of the flare tube 9 is omitted.

The gripping tool 20 includes a pair of leaf springs 21a, 21b that are spaced apart from each other, and a moving body 22 that supports the pair of leaf springs 21a, 21b. The moving body 22 is formed by bending a plate-shaped member, and a pair of plate springs 21a and 21b are attached to one plane part. The other plane portion of the movable body 22 extends along the bending line.

The flare dropping device 100 includes a base member 40 having a slit 41 into which the other flat portion of the movable body 22 is inserted. The slit 41 extends in a predetermined direction (the left-right direction in FIG. 4(A)), and the movable body 22 can move within the slit 41 in the predetermined direction. When the movable body 22 moves toward one end of the slit 41 (the right end in FIG. 4(A)), the pair of leaf springs 21a and 21b enter the inside of the accommodating portion 10. When the movable body 22 moves toward the other end of the slit 41 (the left end in FIG. 4A), the pair of leaf springs 21a and 21b withdraw from the housing portion 10.

When the pair of leaf springs 21a, 21b enters the inside of the housing part 10, the flare tube 9 housed in the housing part 10 is sandwiched between the pair of leaf springs 21a, 21b. At this time, the pair of leaf springs 21a and 21b are pushed apart by the flare tube 9, and the restoring force of the pair of leaf springs 21a and 21b acts on the flare tube 9. As a result, the flare tube 9 is held by the pair of leaf springs 21a and 21b.

When the movable body 22 moves toward the other end of the slit 41 (the left end in FIG. 4(A)) with the pair of leaf springs 21a and 21b gripping the flare tube 9, the pair of leaf springs 21a and 21b are accommodated. Exit from Department 10. As a result, the flare tube 9 is taken out from the housing section 10.

The gripper 20 is moved by a motor 42 serving as a drive source. The motor 42 is connected to a disc 44 via a transmission 43. When the motor 42 is driven, the disc 44 rotates. The disc 44 is connected to the movable body 22 of the gripper 20 via a Scotch yoke mechanism 45 that converts rotational motion into linear motion.

The Scotch yoke mechanism 45 includes a mover 45a attached to the disk 44 and a rod-shaped member 45b attached to the moving body 22. The mover 45a is located away from the rotation axis of the disc 44. When the disk 44 rotates, the mover 45a moves around the rotation axis of the disk 44. A groove 45c is formed in the rod-shaped member 45b, and the slider 45a is inserted into the groove 45c. The groove 45c extends in a direction (vertical direction in FIG. 4A) that intersects the direction in which the rotation axis of the disk 44 extends and the direction in which the slit 41 extends.

FIG. 4 shows a state in which the mover 45a is closest to the accommodating portion 10 (a state in which it has moved to the rightmost side in FIG. 4(A)). FIG. 5 shows a state in which the disk 44 has been rotated by 90 degrees from the state shown in FIG. 4 (a state in which the mover 45a has moved to the uppermost position in FIG. , which corresponds to FIGS. 4(A) to 4(E). In addition, illustration of the ignition part 9b and the collar body 9d of the flame tube 9 is also omitted in FIG.

When the disk 44 rotates 90 degrees from the state shown in FIG. 4, the mover 45a moves along the groove 45c while pushing the rod-shaped member 45b in the direction away from the housing part 10 (to the left in FIG. 4A). do. Thereby, as shown in FIG. 5, the rod-shaped member 45b moves in a direction away from the housing section 10. Since the movable body 22 of the gripping tool 20 is attached to the rod-shaped member 45b, the gripping tool 20 moves in the direction away from the accommodating portion 10 due to the movement of the rod-shaped member 45b.

FIG. 6 shows a state in which the disk 44 is further rotated by 90 degrees from the state shown in FIG. 4(A) to (E) are diagrams corresponding to FIG. In addition, in FIG. 6 as well, illustration of the ignition part 9b and the collar body 9d of the flare tube 9 is omitted.

When the disk 44 further rotates by 90° from the state shown in FIG. 5, the mover 45a moves along the groove 45c while further pushing the rod-shaped member 45b in the direction away from the housing portion 10 (to the left in FIG. 5A). and move. Thereby, as shown in FIG. 6, the rod-shaped member 45b and the gripping tool 20 move to the position farthest from the housing section 10.

Although not shown, when the disk 44 further rotates by 90 degrees from the state shown in FIG. while moving along the groove 45c. As a result, the rod-shaped member 45b and the gripping tool 20 move in a direction approaching the accommodating portion 10. When the disk 44 rotates 180 degrees from the state shown in FIG. 6, the rod-shaped member 45b and the gripping tool 20 move to the position closest to the housing part 10. That is, the state returns to the state shown in FIG.

In this way, the gripping tool 20 is reciprocated by the drive of the motor 42. The mechanism for reciprocating the gripper 20 is not limited to the form using the motor 42 and the Scotch yoke mechanism 45. The mechanism for reciprocating the gripper 20 may use a motor 42 and a slider crank mechanism, or may be a reciprocating drive device such as a fluid pressure cylinder.

As shown in FIGS. 5(A) to 5(E), when the gripper 20 moves in a direction away from the accommodating part 10 (to the left in FIG. 5(A)), the flare tube 9 is taken out from the accommodating part 10.

As shown in FIGS. 6A to 6E, on the movement path of the flare tube 9 when the gripping tool 20 moves to the farthest position from the accommodating portion 10, there is a restriction member 50 that restricts the movement of the flare tube 9. provided. The restriction member 50 is attached to the base member 40.

Movement of the gripper 20 is not restricted by the restriction member 50 and is allowed. Therefore, when the gripper 20 moves to the positions shown in FIGS. 6A to 6E, the gripper 20 moves while the movement of the flare tube 9 is restricted by the restriction member 50. Therefore, the flare tube 9 pushes the pair of leaf springs 21a, 21b apart and comes out from between the pair of leaf springs 21a, 21b. As a result, the flare tube 9 is released from the gripper 20 and dropped onto the road surface.

In this way, the gripping tool 20 grips the flare tube 9 housed in the housing section 10, takes out the flare tube 9 from the housing section 10, releases the flare tube 9, and drops it onto the road surface.

When the gripper 20 takes out the flare tube 9 from the storage portion 10 and reaches the position shown in FIG. 5, the motor 42 stops and the gripper 20 stops. Thereafter, the laser irradiation section 30 irradiates the flare tube 9 held by the gripper 20 (more specifically, the ignition section 9b of the flare tube 9) with a laser beam. As a result, heat is applied to the ignition portion 9b, and the flare tube 9 is ignited. After igniting the flare tube 9, the motor 42 is driven to move the gripper 20 to the position shown in FIG. As a result, the ignited flare tube 9 is dropped onto the road surface.

In this way, the laser irradiation section 30 irradiates the flare tube 9 held by the grip tool 20 with a laser beam after the grip tool 20 takes out the flare tube 9 from the accommodating section 10 and before the flare tube 9 is released. ignite. Therefore, even when the flare tube 9 is ignited, contact between the flare tube 9 and the laser irradiation section 30 does not occur. Therefore, the flare tube 9 can be repeatedly and stably ignited and dropped onto the road surface without causing wear or adhesion of abrasions.

Movement of the gripper 20 and its stopping, and laser emission by the laser irradiation unit 30 and its stopping are controlled based on the rotation angle of the disc 44. The rotation angle of the disc 44 is detected, for example, by a rotation angle sensor. The control of the gripper 20 and the laser irradiation unit 30 is not limited to the form in which it is performed by detecting the rotation angle of the disk 44, but may be performed by detecting the position of the mover 45a, the rod-shaped member 45b, or the gripper 20. The positions of the mover 45a, the rod-shaped member 45b, or the gripper 20 are detected using, for example, a touch sensor.

FIG. 7 is a diagram showing the positional relationship between the ignition surface 9e of the flare tube 9 and the laser irradiation section 30. As shown in FIG. 7, the laser irradiation section 30 emits a laser beam in a direction inclined with respect to the ignition surface 9e, and irradiates the ignition section 9b located at the center of the ignition surface 9e. Note that the laser irradiation position does not necessarily have to be at the center of the ignition surface 9e as shown in FIG. 7, and may be slightly shifted from the center of the ignition surface 9e as long as the flare tube 9 can be ignited.

The present invention is not limited to a form in which the laser irradiation section 30 emits a laser when the gripping tool 20 stops; the laser irradiation section 30 irradiates the flare tube 9 with laser while moving the gripping tool 20 to ignite the flare tube 9. You may.

As shown in FIGS. 4 to 6, the flare dropping device 100 includes a wall portion 60 fixed to the base member 40. As shown in FIGS. An opening 61 is formed in the wall portion 60 . When the gripper 20 takes out the flare tube 9 from the storage part 10, the gripper 20 passes through the opening 61. The wall portion 60 may be a part of the accommodating portion 10 or may be a separate portion from the accommodating portion 10.

The wall portion 60 is provided with an opening/closing member 62 that opens and closes the opening 61. The opening/closing member 62 is a rotating door. The opening/closing member 62 is not limited to a rotary type, but may be a sliding type as long as it can open and close the opening 61.

As shown in FIG. 5, the opening/closing member 62 closes the opening 61 when the laser irradiation unit 30 irradiates the flare tube 9 with laser. Therefore, the progress of the laser and fire through the opening 61 is blocked by the opening/closing member 62. Therefore, it is possible to prevent the laser from irradiating the flare tube 9 housed in the housing section 10 or prevent the ignited flame tube 9 from transferring to the flare tube 9 housed in the housing section 10.

In order to more reliably prevent ignition of the flare tube 9 housed in the housing section 10, it is preferable that the wall section 60 and the opening/closing member 62 have fireproof performance.

As shown in FIG. 6, it is preferable that the opening/closing member 62 closes the opening 61 even when the gripper 20 releases and drops the flare tube 9. In this case, it is possible to prevent the flame of the ignited flare 9 from being transferred to the flare 9 housed in the storage section 10 when the ignited flare 9 is dropped.

8(A) is an enlarged view of section VIIIA shown in FIG. 4(A), and FIG. 8(B) is a sectional view taken along line VIIIB-VIIIB shown in FIG. 8(A). As shown in FIGS. 8(A) and 8(B), the flare dropping device 100 includes a spring hinge 63 as a biasing member that biases the opening/closing member 62 in a direction to close the opening 61.

One end of the spring hinge 63 is fixed to the wall portion 60, and the other end of the spring hinge 63 is fixed to the opening/closing member 62. The spring hinge 63 is provided across the wall portion 60 and the opening/closing member 62 in a deformed state, and exerts a restoring force. Due to this restoring force, the spring hinge 63 urges the opening/closing member 62 in the direction of closing the opening 61.

The biasing member is not limited to the spring hinge 63, but may be a coil spring provided across the wall portion 60 and the opening/closing member 62.

The gripping tool 20 is provided with a pair of protrusions 23a and 23b that project from the movable body 22 in the moving direction of the gripping tool 20. The protrusions 23a and 23b are separated from each other, and the flare tube 9 can be placed between the protrusions 23a and 23b.

FIG. 9(A) is a diagram showing a state in which the opening/closing member 62 is closed, corresponding to FIG. 8(B), and FIG. 9(B) shows how the gripping tool 20 is removed from the state shown in FIG. FIG. 8B is a diagram corresponding to FIG. 8(B) showing a state in which the device is brought close to the accommodating portion 10;

As shown in FIG. 9A, when the gripper 20 is away from the opening/closing member 62, the protrusions 23a, 23b are closer to the opening/closing member 62 than the pair of leaf springs 21a, 21b. Therefore, as shown in FIG. 9(B), when the gripping tool 20 is brought close to the accommodating part 10, the protruding parts 23a and 23b come into contact with the opening/closing member 62, and the opening/closing member 62 is pushed by the protruding parts 23a, 23b. It is displaced in the direction of opening the opening 61. By further moving the gripping tool 20, the protrusions 23a and 23b are inserted between the opening and closing member 62, as shown in FIG. 8(B).

Although not shown, when the gripping tool 20 comes out of the storage part 10, the opening/closing member 62 is biased by the spring hinge 63 and displaced in the direction of closing the opening 61 along with the protrusions 23a and 23b. When the protrusions 23a, 23b are pulled out from the opening 61, the opening/closing member 62 is closed, as shown in FIG. 9(A).

In this way, when the gripper 20 enters the housing section 10, the opening/closing member 62 is pushed by the gripper 20 and is displaced in the direction of opening the opening 61 against the urging force of the spring hinge 63, and the gripper 20 is moved in the direction of opening the opening 61. When exiting from the housing portion 10, the opening/closing member 62 is biased by the spring hinge 63 and is displaced in a direction to close the opening 61. Therefore, when the gripper 20 takes out the flare tube 9 from the accommodating part 10, the opening 61 is closed by the opening/closing member 62. Therefore, it is possible to more reliably prevent the laser from irradiating the flare tube 9 housed in the housing section 10 or the ignited flame tube 9 from transferring to the flare tube 9 housed in the housing section 10.

Since the protrusions 23a and 23b, which are different from the pair of leaf springs 21a and 21b that grip the flare tube 9, push the opening/closing member 62 against the biasing force of the spring hinge 63, the leaf springs 21a, 21b press the opening/closing member 62 when the opening/closing member 62 is opened. It does not transform into Therefore, the flare tube 9 can be gripped more reliably using the pair of leaf springs 21a and 21b.

As shown in FIG. 1, the flare dropping device 100 further includes a guide duct 70 that guides the flare 9 released from the gripper 20 (see FIG. 4, etc.) to the road surface. The guiding duct 70 includes a vertical portion 71 that extends vertically and is located below a position where the gripping tool 20 releases the flare tube 9 (hereinafter also referred to as a “release position of the flare tube 9”), and an inclined portion connected to the vertical portion 71. 72.

The inclined portion 72 is inclined with respect to the longitudinal direction of the vehicle 1 and guides the flare tube 9 in either the left or right direction of the vehicle 1 with respect to the release position of the flare tube 9. Therefore, the flare tube 9 is dropped on either the left side or the right side of the vehicle 1. Therefore, the flare tubes 9 can be easily dropped in accordance with the lanes where vehicle traffic is restricted.

FIG. 10 is a diagram for explaining the relationship between the dropping position of the flare tube 9 and the lane where vehicle traffic is restricted. FIG. 10(A) is a diagram when the inclined portion 72 is set to guide the vehicle 1 to the left with respect to the release position of the flare tube 9, and FIG. It is a diagram when the slope part 72 is set so as to guide the vehicle 1 to the right.

As shown in FIG. 10(A), when the inclined portion 72 is set so as to guide the flare tube 9 to the left side of the vehicle 1 with respect to the release position, the flare tube 9 is dropped to the left side of the vehicle 1. Therefore, it is suitable for, for example, imposing high traffic restrictions on the right lane on a road with two lanes on each side. As shown in FIG. 10(B), when the inclined portion 72 is set so as to guide the flare tube 9 to the right side of the vehicle 1 with respect to the release position, the flare tube 9 is dropped to the right side of the vehicle 1. Therefore, it is suitable, for example, for imposing high traffic restrictions on the left lane on a road with two lanes on each side.

The guide duct 70 is detachably supported by the base member 40 (see FIG. 4, etc.). By attaching and detaching the guide duct 70, the base member 40 can be placed in a leftward state with the inclined portion 72 directed toward the left of the vehicle 1 (the state shown in FIG. 10A), and a rightward state with the inclined portion 72 directed toward the right of the vehicle 1 The state of the guiding duct 70 can be changed to the direction state (the state shown in FIG. 10(B)). Therefore, it is possible to easily switch between dropping the flare 9 on the left side of the vehicle 1 and dropping the flare 9 on the right side of the vehicle 1. Therefore, the dropping position of the flare canister 9 can be easily changed in accordance with the lane where vehicle traffic is restricted.

The base member 40 may support the guide duct 70 rotatably around a vertical axis. Even in this case, it is possible to easily switch between dropping the flare 9 on the left side of the vehicle 1 and dropping the flare 9 on the right side of the vehicle 1. Therefore, the dropping position of the flare canister 9 can be easily changed in accordance with the lane where vehicle traffic is restricted.

Note that the guide duct 70 may have a configuration in which it does not have the vertical part 71 and only has the inclined part 72. Also in this case, the flare tube 9 is dropped on either the left side or the right side of the vehicle 1. Therefore, the flare tubes 9 can be easily dropped in accordance with the lanes where vehicle traffic is restricted.

According to the above embodiment, the following effects are achieved.

In the present embodiment, the laser irradiation unit 30 irradiates the flare tube 9 held by the grip tool 20 with a laser beam after the grip tool 20 takes out the flare tube 9 from the housing section 10 until the flare tube 9 is released. Light the 9. Therefore, even when the flare tube 9 is ignited, contact between the flare tube 9 and the laser irradiation section 30 does not occur. Therefore, the flare tube 9 can be repeatedly and stably ignited and dropped onto the road surface without causing wear or adhesion of abrasions.

The opening/closing member 62 closes the opening 61 when the laser irradiation section 30 irradiates the flare tube 9 with laser. Therefore, the progress of the laser and fire through the opening 61 is blocked by the opening/closing member 62. Therefore, it is possible to prevent the laser from irradiating the flare tube 9 housed in the housing section 10 or prevent the ignited flame tube 9 from transferring to the flare tube 9 housed in the housing section 10.

When the gripper 20 enters the housing part 10 , the opening/closing member 62 is pushed by the gripper 20 and is displaced in the direction of opening the opening 61 against the biasing force of the spring hinge 63 , and the gripper 20 is removed from the housing part 10 . When exiting, the opening/closing member 62 is biased by the spring hinge 63 and is displaced in the direction of closing the opening 61. Therefore, when the gripper 20 takes out the flare tube 9 from the accommodating part 10, the opening 61 is closed by the opening/closing member 62. Therefore, it is possible to more reliably prevent the laser from irradiating the flare tube 9 housed in the housing section 10 or the ignited flame tube 9 from transferring to the flare tube 9 housed in the housing section 10.

The inclined portion 72 is inclined with respect to the longitudinal direction of the vehicle 1 and guides the flare tube 9 in either the left or right direction of the vehicle 1 with respect to the release position of the flare tube 9. Therefore, the flare tube 9 is dropped on either the left side or the right side of the vehicle 1. Therefore, the flare tubes 9 can be easily dropped in accordance with the lanes where vehicle traffic is restricted.

By attaching and detaching the guide duct 70, the base member 40 changes the state of the guide duct 70 into a leftward state in which the inclined portion 72 is directed toward the left of the vehicle 1 and a rightward state in which the inclined portion 72 is directed toward the right of the vehicle 1. can be changed. Therefore, it is possible to easily switch between dropping the flare tube 9 on the left side of the vehicle 1 and dropping the flare tube 9 on the right side of the vehicle 1. Therefore, the position at which the flare canister 9 is dropped can be easily changed in accordance with the lane in which the traffic control of the vehicle is being carried out.

The base member 40 supports the guide duct 70 rotatably around a vertical axis. Therefore, by rotating the guide duct 70, it is possible to easily switch between dropping the flare tube 9 on the left side of the vehicle 1 and dropping the flare tube 9 on the right side of the vehicle 1. Therefore, the position at which the flare canister 9 is dropped can be easily changed in accordance with the lane in which the vehicle traffic is restricted.

Although the embodiments of the present invention have been described above, the above embodiments merely show a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments. do not have.

In the above embodiment, the pair of leaf springs 21a and 21b are used to grip the flare tube 9, but the mechanism for gripping the flare tube 9 is not limited to this. As the mechanism for gripping the flare tube 9, for example, a robot hand that can be driven by electric power and switched between a gripping state and a release state may be used.

However, when a robot hand is used, the mechanism for gripping and releasing the flare tube 9 becomes complicated. As a result, it may not be possible to smoothly switch from the gripping state to the release state, and there is a possibility that dropping the flare tube 9 may fail.

As in the above embodiment, the restriction member 50 is provided on the movement path of the flare tube 9 gripped by the gripper 20, and the gripper 20 is moved while the movement of the flare tube 9 is restricted by the restriction member 50. When releasing , the mechanism is simple. Therefore, it is possible to smoothly switch from the grasped state to the released state, and the flare tube 9 can be stably ignited and dropped onto the road surface.

In the above embodiment, the flare dropping device 100 either drops the flare 9 to the left side of the vehicle 1 through the guide duct 70 (see FIG. 10(A)) or drops the flare 9 to the right side of the vehicle 1 (see FIG. 10(A)). Although it has been described that the mode (see B) can be easily switched, the present invention is not limited to this mode. For example, the flare dropping device 100 changes the dropping position of the flare 9 from the left side of the vehicle 1 (see FIG. 10(A)) to the right side (see FIG. 10(B)) by adjusting the installation position of the guide duct 70. It can be easily adjusted to any position in between.

In the embodiment described above, the flare dropping device 100 is installed on the loading platform 2 of the vehicle 1, but the present invention is not limited to this embodiment. For example, as shown in FIG. 11, the flare dropping device 100 may be installed at a step 5 provided at the rear of the loading platform 2. Further, as shown in FIG. 12, a bottom raising stand 6 may be installed on the loading platform 2, and a flare dropping device 100 may be installed on the bottom raising stand 6.
