The present application relates to a cargo transport vehicle for transporting cargo.

Patent Document 1 describes a cargo transport vehicle that transports cargo (stored in a container, loaded on a pallet, etc.) adjacent to the loading/unloading exit of an aircraft cargo hold at an airport, for example. Are listed. This cargo transport vehicle includes, from the front toward the rear facing the aircraft, a front platform, a rear platform, and an extension truck. The cargo is first transferred to the extension trolley from a transport trolley that is attached to the rear of the extension trolley and is separate from the cargo transport vehicle. This transferred cargo is then transferred from the extension truck to the aft platform, from the aft platform to the forward platform, and then loaded from the forward platform into the cargo hold of the aircraft.

Japanese Patent Application Publication No. 2016-199180

By the way, when moving cargo from a transport trolley to an extension trolley, the cargo is usually rotated 90 degrees on the transport trolley before being moved to the extension trolley, so the distance in the front and back direction between the transport trolley and the extension trolley must be set at a predetermined distance. The transport trolley must be placed next to the extension trolley with a distance of 1. Therefore, if the transport cart is placed sideways with the front and rear distances separated by a predetermined distance or more than a predetermined threshold value, when the cargo is moved from the transport cart to the extension cart, the cargo will fall into the gap between the transport cart and the extension cart. It gets stuck and the cargo cannot be moved from the transport trolley to the extension trolley. In addition, the positional relationship between the transport trolley and the extension trolley in the horizontal direction orthogonal to the front-rear direction is also the same, and when the cargo is rotated 90 degrees on the transport trolley, the cargo must be within the width of the extension trolley. For example, it is not possible to move the cargo from the transport trolley to the extension trolley.

However, the cargo transport vehicle described in Patent Document 1 does not consider notifying the driver of the towing tractor that pulls the transport cart of the stopping position of the transport cart with respect to the extension cart. On the other hand, stopping the vehicle at the appropriate location was left entirely to the driver's experience and intuition. Therefore, an inexperienced driver may not be able to stop the transport cart at an appropriate position in one go, and may have to redo positioning, which reduces work efficiency. Furthermore, even for less experienced drivers, visual positioning may be quite difficult at night or on rainy days, requiring guidance from others or relying on the experience of experienced drivers.

An object of the present application is to provide a technique that enables a towing tractor driver to stop a transport cart at an appropriate position relative to a cargo transport vehicle, regardless of the level of driving experience of the driver of the towing tractor.

In order to achieve the above object, the cargo transport vehicle of the present application is a cargo transport vehicle that approaches an aircraft in a substantially perpendicular direction and loads the cargo, and the cargo is loaded onto a transport trolley that is attached next to the cargo transport vehicle. A cargo transport vehicle that moves cargo from a transport trolley, transports the moved cargo and carries it into an aircraft, transports cargo removed from an aircraft, and moves the transported cargo to a transport trolley and loads it. The present invention is characterized in that it includes a light source that emits light indicating the horizontal position of the transport vehicle.

As a result, the driver of the towing tractor that pulls the transport vehicle can visually observe the light emitted from the light source that indicates the position where the transport vehicle is placed next to the vehicle, and then move the transport vehicle next to the freight vehicle in accordance with the irradiation position of the light. As a result, the transport vehicle will naturally stop at the appropriate position, so regardless of the level of driving experience of the towing tractor driver, it is possible to stop the transport vehicle at the appropriate position relative to the cargo transport vehicle. becomes possible.

Furthermore, the light source may be configured to irradiate with one light the position indicating the appropriate gap between the transport trolley and the freight transport vehicle among the horizontal positions of the transport trolley and the stop position in the traveling direction of the transport trolley. good.

As a result, the number of lights irradiated from the light source can be reduced to the minimum one, while producing the above effects, and therefore a cheaper light source can be used. Therefore, it is possible to reduce the manufacturing cost of the entire freight transport vehicle.

In addition, the light source irradiates with at least one beam of light a position that indicates an appropriate gap between the transport vehicle and the cargo transport vehicle among the horizontal positions of the transport vehicle, and The vehicle may have at least one portion that illuminates the parking position in the traveling direction with at least one beam of light.

As a result, the driver of the towing tractor that pulls the transport vehicle can select the position that indicates the appropriate gap between the transport vehicle and the cargo transport vehicle among the horizontal positions of the transport vehicle illuminated by the light source, and/or The above effect can be achieved because the light indicating the stop position in the traveling direction can be visually observed and the transport cart can be placed alongside the cargo transport vehicle in accordance with the irradiation position of the light.

In addition, when irradiating the position indicating the appropriate gap between the transport trolley and the cargo transport vehicle with a single beam of light, the part that illuminates the position indicating the appropriate gap between the transport trolley and the cargo transport vehicle may be one selected from a plurality of different positions. Light indicating one position may be emitted.

This allows the light source to emit light at a position that indicates an appropriate gap depending on the size of the cargo loaded on the transport trolley or to be loaded, so even if the size of the cargo changes, the transport trolley can be It becomes possible to stop the transport vehicle at an appropriate position.

In addition, when irradiating the position showing the appropriate gap between the transport trolley and the cargo transport vehicle with multiple lights, if multiple different positions showing the appropriate gap are irradiated with multiple lights, multiple lights with different aspects may be used. The light may be used for irradiation.

As a result, the towing tractor driver visually observes the light in a manner that corresponds to the size of the cargo loaded or to be loaded on the transport truck, and moves the transport truck next to the freight vehicle in line with the irradiation position of the light. Therefore, even if the size of the cargo changes, the transport cart can be stopped at an appropriate position relative to the cargo transport vehicle.

In order to achieve the above object, the light irradiation method of the present application approaches an aircraft in a substantially perpendicular direction, and moves the cargo loaded on a transport trolley that is next to a cargo transport vehicle loaded with cargo from the transport trolley. , to transport the moved cargo and bring it into the aircraft, as well as to transport the cargo removed from the aircraft, and to move the transported cargo onto the transport trolley and load it. It is characterized by emitting light that indicates the position.

As a result, the driver of the towing tractor that pulls the transport vehicle can visually observe the light emitted from the light source that indicates the position where the transport vehicle is placed next to the vehicle, and then move the transport vehicle next to the freight vehicle in accordance with the irradiation position of the light. As a result, the transport vehicle will naturally stop at the appropriate position, so regardless of the level of driving experience of the towing tractor driver, it is possible to stop the transport vehicle at the appropriate position relative to the cargo transport vehicle. becomes possible.

FIG. 2 is a schematic diagram showing how a container is being moved from a transport cart to a container/pallet loader according to an embodiment of the present application. FIG. 1 is a plan view of a freight transport vehicle according to an embodiment of the present application. 2 is a diagram showing an example of an irradiation mode different from the light irradiation mode in FIG. 1. FIG.

Hereinafter, embodiments of the present application will be described in detail based on the drawings.

As shown in FIG. 1, a container/pallet loader 1 (an example of a "cargo transport vehicle") has a front platform 11 (also referred to as a "bridge platform") and a rear platform 12 (also referred to as a "main platform") from the front to the rear. It further includes an extension truck 13 (also referred to as an "extension dolly") connected to the rear of the rear platform 12. In addition, in each figure, when referring to a direction, the direction of the arrow shown in each figure shall be used.

In FIG. 1, a second transport trolley 110b among a plurality of transport trolleys 110a to 110e (five in this embodiment) pulled by a towing tractor 100 is placed next to the extension trolley 13. It is shown. Containers C (an example of "cargo") are loaded on each of the transportation vehicles 110b to 110e, but the container C loaded on the first transportation vehicle 110a has already been moved from the transportation vehicle 110b to the extension vehicle 13 side. Therefore, the container C is not loaded on the transport cart 110a.

When moving the containers C loaded on the transport trolleys 110a to 110e from each transport trolley 110a to 110e to the extension trolley 13, the moving method is the same for each transport trolley 110a to 110e, so the second transport A method for moving the loaded container C from the trolley 110b to the extension trolley 13 will be described as an example.

First, an operator (in this embodiment, the same person as the driver of the towing tractor 100) rotates the container C by 90 degrees, for example, clockwise, on the transport truck 110b. Next, the operator pushes the container C on the transport trolley 110b forward, and moves the front end of the bottom of the container C to the rearmost transport roller of the plurality of transport rollers (not shown) provided on the extension trolley 13. I'll put it on. Then, when the operator instructs the rotation direction of the transport rollers so that the container C is transported forward, the container C is moved from the transport trolley 110b to the extension trolley 13. A plurality of similar conveyance rollers are also provided on the front platform 11 and the rear platform 12, so the container C is conveyed from the extension truck 13 to the rear platform 12, and from the rear platform 12 to the front platform 11. .

As shown in FIG. 2, the front platform 11 and the rear platform 12 are each provided with separate elevator platforms 2 (2a, 2b) that can be raised and lowered in the vertical direction. Each elevator platform 2 (2a, 2b) is vertically expandable and retractable, and is supported from below by a pair of scissor link mechanisms 5, 5 that face each other and are spaced apart from each other in the left-right direction. Each scissor link mechanism 5 is a known mechanism, and is a mechanism that expands and contracts by changing the intersection angle of a pair of support columns 51, 51 extending in an oblique direction. This scissor link mechanism 5 allows the upper surface of each elevator platform 2 (2a, 2b) on the front platform 11 and rear platform 12 to be aligned horizontally with the floor surface of the loading/unloading exit AO of the aircraft A (see FIG. 1). By changing the height according to the type of aircraft A, the container C can be easily transported to the loading/unloading port AO.

A driver's cab 11a is provided on the side of the front platform 11 (in the present embodiment, on the right side). This driver's cab 11a is provided on the elevator platform 2a of the front platform 11, and the operator can easily access the container C on the front platform 11. In the example of FIG. 2, one container C is placed on the front platform 11, and two containers C lined up one after the other are placed on the rear platform 12. can be changed in various ways depending on the settings for how the container C is transported.

Furthermore, a light source L that generates line-shaped light is provided on the side surface of the rear end of the extension truck 13. As shown in FIG. 1, the light source L generates three beams of light R1 to R3 of a predetermined length. The light R1 irradiates a position that indicates an appropriate gap between each of the transportation vehicles 110a to 110e and the extension vehicle 13 among the positions where each of the transportation vehicles 110a to 110e is placed horizontally behind the extension vehicle 13. The light R2 illuminates one end of the width of the container C in the moving direction when the container C is moved from each of the transport trolleys 110a to 110e onto the extension trolley 13, and the light R3 illuminates the other end. In this way, the light source L emits three lights R1 to R3 from different positions in different directions (however, light R2 and light R3 are in the same direction), so it is difficult to configure the light source L with a single light source. If so, it may be configured with two or more light sources.

The driver of the towing tractor 100 visually observes these three lights R1 to R3, and moves each of the transport carts 110a to 110e sideways to the rear of the extension cart 13 in accordance with the irradiation position of each light R1 to R3. The transport carts 110a to 110e will naturally stop at appropriate positions for moving the container C to the extension cart 13. Note that, as a characteristic of the towing tractor 100, each of the transport vehicles 110a to 110e towed follows almost the same trajectory, so if the first transport vehicle 110a is placed next to the irradiation position of the light R1, the second and subsequent vehicles The appropriate gap between the transport carts 110b to 110e and the extension cart 13 is maintained as is.

In this way, the driver of the towing tractor 100 only has to move the transport carts 110a to 110e sideways to the rear of the extension cart 13 in accordance with the irradiation positions of the lights R1 to R3, so even an inexperienced driver can Even if the transportation vehicle 110a to 110e is stopped at a different position, unnecessary work such as re-alignment due to misalignment of the parking position of each of the transportation vehicles 110a to 110e can be avoided.

Furthermore, even at night or in rainy weather, if the driver can visually see the lights R1 to R3, he or she can stop each of the transport vehicles 110a to 110e at an appropriate position, just as in the daytime on a sunny day. In this way, the lights R1 to R3 need to be visible to the driver under any environment. In other words, the lights R1 to R3 need to be visible to the driver both during the daytime during clear weather and at night during bad weather. For this reason, the lights R1 to R3 are preferably laser lights, but other types of light such as LED light may be used as long as they satisfy the above conditions.

Furthermore, since there is no obstacle in the irradiation position of the light R1, there are few restrictions on the position where the light source L is attached to the side surface of the rear end of the extension truck 13. However, since the respective transport carts 110a to 110e are placed next to each of the irradiation positions of the light R2 and the light R3, the respective transport carts 110a to 110e and the containers C loaded thereon are obstacles to the irradiation of the light R2 and the light R3. It is necessary to install the light source L in a position that does not result in the following. For example, the light R2 and the light R3 pass through the gap between the back surface of the cargo loading surface of each of the transport carts 110a to 110e and the road surface and exit to the end of each of the transport carts 110a to 110e on the opposite side to the extension cart 13. A light source L is installed at a position on the side surface of the rear end of the extension truck 13. Therefore, in this case, the predetermined length of the light R2 and the light R3 is a length that exceeds the width of each of the transport carts 110a to 110e in the traveling direction by a predetermined length.

Note that it is difficult to generate light of a predetermined length by irradiating the lights R1 to R3 in a horizontal direction, so by irradiating the lights R1 to R3 diagonally downward, the end of the light is positioned above the road surface. What is necessary is to generate light of a predetermined length.

In this embodiment, the light source L irradiates three predetermined lengths of light R1 to R3 to predetermined positions, and the driver of the towing tractor 100 adjusts the irradiation position of each light R1 to R3. Each of the transport carts 110a to 110e is placed horizontally at the rear of the extension cart 13. However, if the light R1 is made to perform the function of irradiating the appropriate stopping position in the traveling direction of each of the transportation carts 110a to 110e in addition to the function of irradiating the position showing the appropriate gap, it is possible to The light R2 and the light R3 can be omitted. Here, the function of illuminating an appropriate stopping position in the traveling direction of each of the transport carts 110a to 110e is, for example, by adjusting a predetermined length of the light R1 so that the end position of the light R1 becomes an appropriate stopping position. This can be achieved by doing this. In other words, the driver aligns the side surface of each of the transportation vehicles 110a to 110e on the extension vehicle 13 side with the light R1, and also aligns the stopping position of each of the transportation vehicles 110a to 110e in the traveling direction with the end of the light R1. Based on the light R1, each of the transport carts 110a to 110e can be stopped at an appropriate position for moving the container C to the extension cart 13.

Further, in addition to the light R1, one of the light R2 and the light R3 may be irradiated. Thereby, the driver can visually check the position indicating the appropriate gap between each of the transport carts 110a to 110e and the extension cart 13 based on the light R1, and can also visually check the position indicating the appropriate gap between the respective transport carts 110a to 110e and the extension cart 13 based on the light R2 or R3. Since the position of one end of the width of the container C in the moving direction when the container C is moved from each transport trolley 110a to 110e onto the extension trolley 13 can be visually observed, each transport trolley 110a to 110e can be moved in line with these two lights. By stopping, each of the transport carts 110a to 110e will stop at an appropriate position for moving the container C to the extension cart 13.

Further, the size of the container C loaded on each of the transport carts 110a to 110e is not always the same, but varies depending on the situation. In particular, the position indicating the appropriate gap between each of the transport carts 110a to 110e and the extension cart 13 needs to be made wider as the length of the container C in the longitudinal direction becomes longer. To deal with this, it is conceivable to vary the irradiation position of the light R1 depending on the size of the container C. Specifically, since the size of the container C loaded on each of the transport carts 110a to 110e is known in advance, the irradiation position of the light R1 is changed to a position corresponding to the size. Alternatively, the sizes of the containers C that can be loaded on each of the transport carts 110a to 110e are divided at predetermined intervals from the maximum value to the minimum size, and the light is irradiated to a position indicating an appropriate gap in each division, and the mode is set for each division. A plurality of lights are irradiated as the light R1 while changing the color (color, etc.). The driver visually observes the light R1 in a mode corresponding to the size of the container C loaded on each of the transport carts 110a to 110e, and extends each of the transport carts 110a to 110e to the rear of the cart 13 in accordance with the irradiation position of the light R1. side by side. As a result, even if the size of the container C changes, each of the transport carts 110a to 110e can be stopped at an appropriate position relative to the extension cart 13.

Above, we have mainly explained the method of transporting the containers C loaded on each of the transport carts 110a to 110e to the loading/unloading port AO of the aircraft A via the container/pallet loader 1. The method of carrying out the loaded container C from the carry-in/out port AO and loading it onto each of the transport carts 110a to 110e via the container/pallet loader 1 can be easily carried out, so a description thereof will be omitted.

As explained above, the container/pallet loader 1 of the present embodiment is a container/pallet loader 1 that approaches an aircraft A in a substantially vertical direction and loads a container C, and has transport carts 110a to 110e mounted beside it. The container C loaded on the aircraft A is moved from the transport trolleys 110a to 110e, the moved container C is transported and carried into the aircraft A, the cargo carried out from the aircraft A is transported, and the transported container C is moved to the transport trolley 110a. ~Move to 110e and load. The container/pallet loader 1 is equipped with a light source L that emits lights R1 to R3 that indicate the horizontal mounting positions of the transport vehicles 110a to 110e.

According to the container/pallet loader 1 of the present embodiment, the driver of the towing tractor 100 that pulls the transport vehicles 110a to 110e can use the lights R1 to R3 emitted from the light source L to indicate the horizontal position of the transport vehicles 110a to 110e. If the transport vehicles 110a to 110e are placed next to the container/pallet loader 1 according to the irradiation positions of the lights R1 to R3, the transport vehicles 110a to 110e will naturally stop at the appropriate position. Regardless of the driving experience of the driver of the towing tractor 100, the towing tractor 100 can be stopped at an appropriate position relative to the container/pallet loader 1.

In addition, the light source L determines the position where the transport vehicles 110a to 110e are placed horizontally, a position that indicates an appropriate gap between the transport vehicles 110a to 110e and the container/pallet loader 1, and a stop position in the traveling direction of the transport vehicles 110a to 110e. Irradiation is performed with one light R1.

As a result, the number of lights R1 irradiated from the light source L can be reduced to the minimum of one while producing the above-mentioned effects, so a cheaper light source L can be used. Therefore, it is possible to reduce the manufacturing cost of the container/pallet loader 1 as a whole.

In addition, the light source L has a portion that irradiates with at least one light R1 a position that indicates an appropriate gap between the transportation vehicles 110a to 110e and the container/pallet loader 1 among the horizontal positions of the transportation vehicles 110a to 110e, and Of the lateral positions of the carriages 110a to 110e, the parking position in the traveling direction of the transportation carriages 110a to 110e may be provided with at least one of the parts irradiating with at least one light R2, R3.

As a result, the driver of the towing tractor 100 that pulls the transport carts 110a to 110e can check the position between the transport carts 110a to 110e and the container/pallet loader 1 among the horizontal positions of the transport carts 110a to 110e illuminated by the light source L. The light indicating the position indicating the appropriate gap and/or the stop position in the traveling direction of the transport carts 110a to 110e can be visually observed, and the transport carts 110a to 110e can be placed next to the container/pallet loader 1 in accordance with the irradiation position of the light. , it becomes possible to achieve the above effects.

In addition, when irradiating the position indicating the appropriate gap between the transport vehicles 110a to 110e and the container/pallet loader 1 with one light beam, the portion that illuminates the position indicating the appropriate gap can be selected from a plurality of different positions. A light indicating one of the positions is emitted.

As a result, the light source L can irradiate the light R1 at a position that indicates an appropriate gap according to the size of the containers C loaded or to be loaded on the transport carts 110a to 110e, so that the size of the containers C can be changed. However, it is possible to stop the transport vehicles 110a to 110e at appropriate positions relative to the container/pallet loader 1.

In addition, in the case where a plurality of different positions indicating the appropriate gap are irradiated with multiple beams of light, the portion that illuminates the position indicating the appropriate gap between the transport vehicles 110a to 110e and the container/pallet loader 1 is Irradiate with multiple modified lights.

As a result, the driver of the towing tractor 100 visually observes the light R1 in a mode corresponding to the size of the container C loaded or to be loaded on the transport vehicles 110a to 110e, and adjusts the irradiation position of the light R1 to the transport vehicle. 110a to 110e can be placed next to the container/pallet loader 1, so even if the size of the container C changes, it is possible to stop the transport carts 110a to 110e at appropriate positions relative to the container/pallet loader 1. Become.

Note that the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit thereof.

(1) In the above embodiment, the container/pallet loader 1 includes the extension trolley 13 as an example, but the present invention is not limited to this. 11 and a rear platform 12 may also be used. In this case, the light source L may be attached to the side surface of the rear end of the rear platform 12.

(2) In the above embodiment, the light R2 and the light R3 pass through the gap between the back surface of the cargo loading surface of each of the transport vehicles 110a to 110e and the road surface to the opposite side of the extension vehicle 13 of each of the transport vehicles 110a to 110e. Although the irradiation was performed so as to pass through the end portion, the irradiation is not limited to this, and the irradiation may be performed from above the container C. In this case, the light source L may be installed at a position close to the ceiling of the driver's cab 11a, for example. This is because the ceiling of the driver's cab 11a is higher than the height of the container C. Note that, if there is a position in the container/pallet loader 1 that is higher than the height of the container C other than the ceiling of the driver's cab 11a, the light source L may be attached to that position.

(3) In the above embodiment, no measures have been taken in the towing tractor 100 itself to horizontally mount each of the transport carts 110a to 110e at appropriate positions behind the extension cart 13. However, when the towing tractor 100 is capable of automatic operation, mutual communication between the container/pallet loader 1 and the towing tractor 100 allows the towing tractor 100 to control each irradiation position of the lights R1 to R3. It may be possible to automatically recognize the irradiation position and automatically stop the irradiation according to the irradiation position. The container/pallet loader 1 also checks the size of each of the transport vehicles 110a to 110e being towed by the towing tractor 100 and the size of each container C loaded on each of the transport vehicles 110a to 110e by the towing tractor 100 or the ground. The information may be obtained from a system that manages the support vehicle, and the irradiation positions of the lights R1 to R3 may be automatically adjusted.

(4) In the above embodiment, the lights R2 and R3 have been described as indicating the width of the container C in the moving direction, but the light beams R2 and R3 are not limited to this, and may also indicate the stopping position of each of the transport carts 110a to 110e. . FIG. 3 shows an example of the light irradiation mode in this case. The light R4 shown in FIG. 3(a) is emitted in a T-shape, the vertical lines of the T-shape correspond to the light R1, and the horizontal lines indicate the stop positions of the respective transport carts 110a to 110e. Further, the light R5 shown in FIG. 3(b) is irradiated in a cross shape, the vertical lines correspond to the light R1, and the horizontal lines indicate the stopping positions of each of the transport carts 110a to 110e. Furthermore, the light R6 shown in FIG. 3(c) is irradiated in an L-shape rotated by 180 degrees, the vertical line of the L-shape corresponds to the light R1, and the horizontal line indicates the stop position of each of the transport carts 110a to 110e. ing. In this case, the operator of the towing tractor 100 visually observes the position of the light indicating the stop position of each of the transport vehicles 110a to 110e, and stops each of the transport vehicles 110a to 110e at that position. The container C will be stopped at an appropriate position to be moved to the extension trolley 13.

(5) In the above embodiment, the case where each of the transport carts 110a to 110e is installed horizontally behind the extension cart 13 has been described as an example, but each of the transport carts 110a to 110e is arranged in parallel with the container/pallet loader 1. It may be sidelined. In order to deal with this case, the light source L is installed at an appropriate position on one side of the container/pallet loader 1 in the left and right direction in FIG. Just do it like this.

(6) In the above embodiment, the lights R1 to R3 are irradiated to the corners of the cargo loading surface of each of the transport vehicles 110a to 110e, but the lights may be irradiated to the stop positions of the tires of each of the transport vehicles 110a to 110e.
