Description

Luggage loading board and method of transporting luggage using luggage loading board

The present disclosure relates to a luggage loading board and a method for transporting luggage using the luggage loading board.

Conventionally, when loading / unloading luggage from / to the luggage compartment of an aircraft or loading / unloading into a luggage compartment (so-called boarding / exiting), a conveyor device such as a belt loader has been installed near the entrance of the luggage compartment provided on the side of the aircraft. The baggage is placed and moved from the baggage compartment or from the carrier device to the baggage compartment to carry it out or carry in.

To prevent damage to the airframe when the transport device is placed in the vicinity of the aircraft when getting on and off, and the front end of the transport device closest to the aircraft body (for example, the front end of the roller conveyor of the belt loader) hits the airframe. Usually, it is necessary to leave a certain gap between the entrance of the luggage compartment of the aircraft and the tip of the transfer device.

For this reason, in the gap between the entrance of the luggage compartment and the tip of the transfer device, it is necessary for an operator to lift the load manually and move it from the load room to the load room from the load room, which is a heavy labor and alighting It was a cause that took time to be listed.

In order to solve such a problem, for example, in Japanese translations of PCT publication No. 2007-507386, an intermediate transfer means is bridged between the conveyor belt of the transfer device on the ground side and the cargo compartment door area on the aircraft side. An provided system is disclosed. Also, JP 2013-534881 A discloses a conveyor device provided such that a second conveyor is bridged between the first conveyor of the ground-side transport device and the cargo compartment door area on the aircraft side. Has been.

In the system described in JP-T-2007-507386, the intermediate transport means that is bridged between the transport device and the aircraft is connected to the transport device, and the first transport module, the second transport module, and the third transport It has a module. Further, in the conveyor device described in JP 2013-534881 A, the second conveyor bridged between the transport device and the aircraft is connected to the first conveyor, and can be extended telescopically. .

However, in the system described in Japanese translations of PCT publication No. 2007-507386 and the conveyor apparatus described in Japanese translations of PCT publication No. 2013-534881, the structure of the intermediate conveying means and the second conveyor includes many movable parts and driving parts. The system and the device itself are expensive. In addition, there is a problem that failure due to the movable part and the drive part is unavoidable and maintenance cost is high, so that it is difficult to spread except for airports with sufficient funds and maintenance facilities.

Furthermore, in the actual loading and unloading work, since the intermediate transfer means and the second conveyor are fixed to the transfer device, the entire transfer device is moved and moved so as not to damage the aircraft. Adjustments need to be made. For this reason, there is a problem that it takes time to get on and off, and a large number of personnel are required to reduce the time, and the flight schedule is affected.

In view of the above-described problems, the present disclosure aims to provide a luggage loading board capable of realizing simplification and cost reduction of luggage transportation and a luggage transportation method using the luggage loading board. And

The load carrying board according to the first aspect of the present disclosure includes a flat slide board portion in which protruding ribs are arranged in parallel along the load carrying direction on the surface, and a flat plate provided so as to be different from the slide board portion. The support part and one end part are connected to one end part in the load carrying direction of the slide board part, the other end part is connected to the support part, and a protruding rib parallel to the protruding rib of the slide board part is arranged in parallel on the surface. And a crosslinked part.

According to the above configuration, for example, the slide board portion of the cargo loading board is placed on the floor surface of the entrance of the cargo compartment, and the cargo loading board is placed on the frame portion of the transfer device arranged with a predetermined gap in front of the entrance. By disposing the support portion so as to be positioned, the load flowing on the transport device with the bridging portion serving as a bridge can be loaded onto the slide board portion in the cargo compartment.

At this time, since the load first rides on the bridge portion of the load carrying board, the load smoothly moves to the slide board portion without directly hitting the side section of the end portion of the slide board portion. Further, since the protruding ribs are arranged in parallel along the load carrying direction on the surfaces of the slide board portion and the bridging portion, the sliding resistance when sliding the loaded load is reduced. For this reason, even if the load is heavy, the load can be slid inward with a relatively small force.

The luggage loading board according to the second aspect of the present disclosure is the luggage loading board according to the first aspect, wherein the bridging portion is curved toward the back surface side of the slide board portion, A non-slip member is bonded.

According to the above configuration, since the bridging portion has a curved slope shape curved toward the back side of the slide board portion, a drag force from the bending direction is generated against the load of the load. For this reason, there is little possibility that the bridging portion sinks downward due to the load of the load or the load directly hits the side cross section of the end portion of the slide board portion.

Furthermore, since a non-slip member is bonded to the back surface of the slide board portion, it is possible to prevent the load loading board from shifting on the floor surface of the luggage compartment when the load is loaded onto the slide board portion. it can.

According to a third aspect of the present disclosure, a method for transporting a load using a load stacking board loads a flat slide board portion provided on a load stacking board having protruding ribs arranged in parallel on the surface in the load transfer direction. A flat support portion placed on the floor of the entrance of the chamber and connected to the slide board portion so as to be stepped via a bridge portion is placed on the end portion of the transfer device, and flows over the transfer device. Carry the load on the bridge and slide it on the slide board to carry it into the back of the cargo compartment, or slide the cargo in the back of the cargo on the slide board and bridge And carry it out onto the transfer device.

According to the above configuration, the luggage can be easily transported between the entrance of the cargo compartment and the transfer device by laying the cargo loading board between the entrance of the cargo compartment and the transfer device. Further, since the protruding ribs are arranged in parallel on the surface of the load carrying board in the load carrying direction, the sliding resistance when sliding the loaded load is reduced. For this reason, even if the load is heavy, it can be slid with a relatively small force.

In addition, the first part of the load carrying board to be loaded is a bridge with a curved slope or a flat slope that protrudes upward, compared with a configuration in which the entire load board is flat. Thus, there is little possibility that the bridging portion sinks downward in the gap between the luggage compartment and the transfer device due to the load of the load, or the load directly hits the side section of the end portion of the load carrying board. For this reason, a load can be moved smoothly.

According to the present disclosure, it is possible to realize simplification and cost reduction of luggage transportation.

It is a perspective view of the board | substrate for baggage loading which concerns on an example of embodiment. It is CC sectional view taken on the line in FIG. 1A. It is a perspective view which shows the state which spanned between the entrance of a luggage compartment, and the conveying apparatus of the board | substrate for cargo loading which concerns on an example of embodiment. It is a front view which shows the state which looked at the entrance of the luggage compartment in FIG. 2 from the front. It is a side view which shows the state which looked at the entrance of the luggage compartment in FIG. 2 from the side.

Hereinafter, an example of the embodiment of the luggage loading board will be described with reference to FIGS. 1A to 3B.

<Configuration>
The load carrying board 70 according to the present embodiment is made of a resin material such as injection molded polyacetal (POM), and as shown in FIGS. And a guide board portion 74 joined to the portion.

The slide board portion 72 is a rectangular flat thin plate member, and includes a plurality of linear ribs 76 having a triangular cross-section projecting on the front surface side (upper surface side in FIG. 1B) and the back surface side (lower surface side in FIG. 1B), and diagonally Ribs 78 are formed. Further, the linear ribs 76 are arranged in parallel along the longitudinal direction of the slide board portion 72 at intervals.

On the other hand, the oblique ribs 78 are arranged in parallel at intervals so as to obliquely intersect the linear ribs 76. The protruding height of the oblique rib 78 on the front surface side and the back surface side of the slide board portion 72 is set lower than the protruding height of the linear rib 76.

Further, the space between the straight rib 76 and the oblique rib 78 penetrates from the front surface to the back surface of the slide board portion 72. That is, the slide board 72 is formed in a mesh shape (mesh shape) by the straight ribs 76 and the oblique ribs 78.

As shown in FIG. 1A, the slide board portion 72 is formed with radial ribs 79 that extend radially from the center portion to the end portion of the slide board portion 72. For this reason, at the time of injection molding of the slide board portion 72, the resin injected into the mold (not shown) does not stay at the intersection (merging portion) and flows evenly to the end portion of the resin flow path.

A reinforcing portion 80 is provided at one end in the longitudinal direction of the slide board 72 (the right end in FIG. 1B). The reinforcing portion 80 is not in a mesh shape (mesh shape), and on the front and back surfaces of the reinforcing portion 80, vertical ribs 82 parallel to the straight ribs 76 and horizontal ribs 84 orthogonal to the vertical ribs 82 are in a lattice shape. Is formed. For this reason, the strength of the reinforcing portion 80 is higher than that of the slide board portion 72.

The vertical rib 82 and the horizontal rib 84 have a triangular cross section, and the protruding height of the horizontal rib 84 on the front surface side and the back surface side of the reinforcing portion 80 is lower than the protruding height of the vertical rib 82. . Further, the reinforcing portion 80 is formed in a stepped portion 86 that is lowered by one step on the back surface side with respect to the slide board portion 72, and the stepped portion 86, and is arranged at intervals along the longitudinal direction of the slide board portion 72. A plurality of (in this embodiment, five locations) through-holes 88.

Further, a non-slip sheet 104 is bonded to the back surface of the slide board portion 72 with an adhesive. The sheet 104 is made of urethane resin, and covers the entire surface except the stepped portion 86 on the back surface of the slide board portion 72.

The guide board portion 74 includes a bridging portion 90, a flat joint portion 92 provided at one end portion of the bridging portion 90, and a flat support portion 94 provided at the other end portion of the bridging portion 90. . Similarly to the reinforcing portion 80, longitudinal ribs 96 parallel to the straight ribs 76 and transverse ribs 98 orthogonal to the longitudinal ribs 96 are formed on the surface of the guide board portion 74 in a lattice shape.

For this reason, the strength of the guide board portion 74 is higher than that of the slide board portion 72. The vertical rib 96 and the horizontal rib 98 have a triangular cross section, and the protruding height of the horizontal rib 98 on the surface side of the guide board portion 74 is lower than the protruding height of the vertical rib 96.

The bridging portion 90 has a strength that can be bent and deformed, and has a curved slope shape curved toward the back surface (lower side) so as to be convex toward the front surface side (upper side) of the slide board portion 72. Further, the joint portion 92 includes a plurality of (five places in the present embodiment) through holes 100 at positions corresponding to the through holes 88 of the reinforcing portion 80.

Also, blind rivets 102 are inserted into the through holes 88 and the through holes 100 and crimped. That is, the reinforcing portion 80 and the joint portion 92, that is, the slide board portion 72 and the guide board portion 74 are joined to each other by the blind rivet 102.

At this time, since the height of the vertical rib 82 of the reinforcing portion 80 and the height of the vertical rib 96 of the joint portion 92 is higher than the height of the head of the blind rivet 102, the head of the blind rivet 102 is the surface of the load carrying board 70 and Does not protrude from the back side. Further, the surface of the slide board portion 72 and the surface of the joint portion 92 of the guide board portion 74 have the same height (that is, on the same plane).

The support portion 94 is connected to the joint portion 92 via the bridging portion 90, and is one level lower than the joint portion 92 (slide board portion 72) (50 mm to 100 mm in this embodiment). The position of the support portion 94, the curvature of the bridging portion 90, and the like are appropriately determined depending on the place where the load carrying board 70 is disposed and the purpose of use.

<Loading method>
As shown in FIGS. 2, 3 A, and 3 B, the load carrying board 70 is used when the load N is loaded and unloaded into the luggage compartment 122 of the aircraft 120 using the belt loader 110.

The belt loader 110 includes a conveyor 112 that is rotationally driven around a drive shaft 112A shown in FIG. 3B, and the height and angle of the conveyor 112 can be adjusted by an adjusting mechanism (not shown). On the other hand, in the aircraft 120, an entrance 124 of the cargo compartment 122 is formed on the side surface of the fuselage 120A, and the floor surface 122A of the cargo compartment 122 extends toward the inner side of the fuselage 120A.

3A, the lower end portion 124A of the entrance 124 of the luggage compartment 122 is curved along the curve of the fuselage 120A of the aircraft 120. For this reason, in this embodiment, the left side in FIG. 3A of the lower end portion 124A is about 30 mm higher than the right side.

When loading the luggage N in the cargo compartment 122 of the aircraft 120, first, the end portion 110 A of the belt loader 110 is arranged near the entrance 124 of the cargo compartment 122 of the aircraft 120. At this time, in order to prevent the belt loader 110 from hitting the fuselage 120A, the end 110A of the belt loader 110 is obliquely lower than the lower end 124A of the entrance 124 of the cargo compartment 122 of the aircraft 120, as shown in FIG. It is arranged with a gap in the direction.

Next, the two cargo loading boards 70 A and 70 B are placed between the entrance 124 of the luggage compartment 122 and the belt loader 110. Specifically, the slide board portion 72 of the

luggage loading boards

70A and 70B is placed on the floor surface 122A of the luggage compartment 122, and the support portion 94 of the

luggage loading boards

70A and 70B is attached to the end portion 110A of the belt loader 110. Place.

At this time, the longitudinal direction of the cargo loading board 70 (the

cargo loading boards

70A and 70B) is the carrying direction of the cargo N. Since the left and right heights in FIG. 3A of the lower end portion 124A of the entrance 124 of the luggage compartment 122 are different, the distance between the lower end portion 124A and the end portion 110A of the belt loader 110 is also different. For this reason, the load carrying board 70A and the load carrying board 70B have different heights.

Specifically, the height L1 of the left luggage loading board 70A in FIG. 3A is 80 mm, and the height L2 of the right luggage loading board 70B in FIG. 3A is 50 mm.

Next, the plurality of slider boards 108 provided with the straight ribs 106 are placed on the floor surface 122A of the luggage compartment 122 of the aircraft 120 along the transport route of the luggage N. Then, the load N is placed on the conveyor 112 of the belt loader 110, and the load N is transported to the end 110 A of the belt loader 110 by rotating the conveyor 112.

As shown in FIG. 3B, the load N transported to the end 110A of the belt loader 110 rides on the bridging portion 90 of the load stacking board 70 (the

load stacking boards

70A and 70B) as it is. Since the bridging portion 90 is curved toward the back side of the load carrying board 70, the luggage N riding on the bridging portion 90 is pushed up by the drag of the bridging portion 90 that is bent and deformed by the load of the load N.

At this time, by pushing the load N, the load N is slid onto the slide board 72 by sliding on the vertical rib 96 of the bridge portion 90. Thereafter, by further pushing the load N, the load N is carried in the depth direction of the load chamber 122 by sliding on the straight rib 76 of the slide board portion 72 and the straight rib 106 of the slider board 108.

When the cargo N is unloaded from the cargo compartment 122 of the aircraft 120, the cargo N in the rear direction of the cargo compartment 122 is placed on the straight rib 106 of the slider board 108, on the straight rib 76 of the slide board portion 72, and bridged. The vertical rib 96 of the section 90 is slid onto the conveyor 112 of the belt loader 110. After the load N is unloaded, the load loading board 70 is stored in a storage container (not shown) provided in the belt loader 110.

<Action, effect>
According to the present embodiment, the luggage loading board 70 is simply bridged between the entrance 124 of the luggage compartment 122 and the belt loader 110, and the luggage N can be easily placed between the entrance 124 of the luggage compartment 122 and the belt loader 110. Can be transported.

At this time, straight ribs 76 and vertical ribs 82 and 36 are formed on the surface of the baggage loading board 70 along the longitudinal direction, which is the conveyance direction of the load N, and the load N is on the straight ribs 76 and the vertical ribs. Slide on 82,36. For this reason, the frictional resistance of the load N is reduced, and the load N can be transported with a small force even when the load N is heavy.

In the present embodiment, the bridge portion 90 on which the load N of the load carrying board 70 rides has a curved slope shape, and the load N flowing on the belt loader 110 is bridged to the slide board portion 72 with the bridge portion 90 serving as a bridge. Let it ride.

For this reason, as compared with the configuration in which the entire luggage loading board 70 is flat, the bridging portion 90 sinks downward in the gap between the luggage compartment 122 and the belt loader 110 due to the load of the luggage N, There is little possibility that N directly hits the side cross section of the end portion of the load carrying board 70. Therefore, the luggage N can be transported smoothly.

Note that the height of the aircraft 120 rises and falls according to the total load of all the loads N loaded therein. That is, when the total load of the luggage N is large, the height of the floor surface 122A of the luggage compartment 122 is lower than that when the total load of the luggage N is small. The distance between the belt loader 110 and the end 110A of the belt loader 110 also changes.

Here, since the bridging portion 90 of the luggage loading board 70 can be bent and deformed, the bridging portion 90 can be changed according to the distance between the lower end portion 124A of the entrance 124 of the luggage compartment 122 and the end portion 110A of the belt loader 110. By bending, the height between the slide board portion 72 and the support portion 94 of the load carrying board 70 can be finely adjusted.

Even when the bridging portion 90 is bent, since the load carrying board 70 is supported by the end portion 110A of the belt loader 110 by the support portion 94, the load N can be transported in a stable state. it can.

Further, since the sheet 104 is adhered to the back surface of the slide board portion, the load loading board 70 is displaced on the floor surface 122A of the luggage compartment 122 when the load N rides on the slide board portion 72. Can be suppressed.

Furthermore, the luggage loading board 70 is accommodated in the accommodating container of the belt loader 110 when not in use. For this reason, it is not necessary to store the luggage loading board 70 in the luggage compartment 122, and no space is taken up in the luggage compartment 122. Since the load carrying board 70 is a resin-made thin plate-like member, it is easy to carry and can be easily bridged between the entrance 124 of the luggage compartment 122 and the belt loader 110.

For example, in the above embodiment, the slide board portion 72 and the guide board portion 74 of the load carrying board 70 are joined by the blind rivet 102, but the slide board portion 72 and the guide board portion 74 are integrally formed. May be.

In addition, as a method of joining the slide board portion 72 and the guide board portion 74, various methods such as a method of joining in a state where the angle of each other can be adjusted by a hinge, and a method of locking by a hook can be exemplified. . Furthermore, it is possible to connect the slide board part 72 and the guide board part 74 by placing the guide board part 74 on the slide board part 72 without joining them.

Moreover, in the said embodiment, although parts other than the level | step-difference part 86 of the back surface of the slide board part 72 were covered with the sheet | seat 104, it is set as the structure which covers the whole back surface including the level | step-difference part 86 of the slide board part 72 with the sheet | seat 104. Also good. In addition, when the floor surface 122 A of the luggage compartment 122 is difficult to slide, the sheet 104 may not be provided on the back surface of the slide board portion 72.

In the above embodiment, the bridging portion 90 has a curved slope shape. However, the bridging portion 90 has a strength that can be bent and deformed, and can have a shape that can connect the slide board portion 72 and the support portion 94 that are stepped. For example, it may be a plane slope shape.

Moreover, although the cross section of the linear rib 76, the diagonal rib 78, the

vertical ribs

82 and 96, and the

horizontal ribs

84 and 98 was a rhombus shape or a triangular shape, the cross section may be an arc shape, an edge shape, or the like. .

Furthermore, in the above-described embodiment, the case where a load is loaded in the luggage compartment 122 of the aircraft 120 has been described. However, the load carrying board 70 of the present disclosure can be used for various uses in various places, such as when loading a load on a bus or truck loading platform.
