[Industrial applications]

 The present invention relates to an unloading work vehicle for handling passenger luggage or airport cargo (hereinafter, simply referred to as cargo in the present specification) at an airport, and more specifically, an airport pallet placed on a dolly (truck). It relates to a work vehicle for unloading the cargo wrapped in the net above.

[0002]

[Prior art and its problems]

 As is well known, at airports, facilities that handle passengers and cargo are called terminal buildings or cargo terminal buildings, where the work of dismantling, unitizing, sorting, and sorting cargo is performed. It is being appreciated.

Incidentally, there is a system called a pallet loading system, for example, in order to unitize the cargo. This is a method in which cargo classified by loading and unloading airports is placed on a flat pallet for airports, wrapped with vinyl sheets and nets, and loaded into the cargo compartment of the aircraft as it is. At that time, various cargo handling vehicles such as a lift loader are used for loading and unloading cargo on the pallet, which are mechanized (for example, (See Japanese Patent Publication No. 64-6967, Japanese Patent Publication No. 63-15210, Japanese Patent Publication No. 51-19645).

However, in order to load or unload cargo on a pallet (hereinafter, these are referred to as pallet unloading work), this is done manually, and this work requires a large pile of stacked cargo. At present, for example, if it reaches a height of 3 ^m, it is extremely dangerous work. Therefore, mechanization of pallet unloading work is strongly required.

Therefore, the present inventors have been eagerly performing trial and error to meet such a request. For example, a cross arm lifter supporting a forward and reverse conveyor (see, for example, Japanese Patent Publication No. 50-13550 and Japanese Patent Publication No. 52-35073) is applied to pallet unloading work. I tried.

By the way, in the pallet loading system, the cargo on the pallet is not demolished as it is, but is subdivided by a forklift to carry out collation inspection and storage. Therefore, if the cross arm type lifter with Conveyor shown in the above-mentioned publication is applied to this pallet unloading work, it will be applied as it is because this lifter is a large-scale one such as a warehouse. Of course, some of the goods on the pallet are transferred to a flat box-shaped skid into which a fork can be inserted, and when this skid is carried by a forklift, it is blocked by the presence of a lifter. -The clift cannot move forward, thus moving the heavy skid carrying the cargo towards the stopped forklift. However, there is a problem that the skid cannot be moved on the conveyor supported by the lifter.

[0007]

[Means for Solving the Problems]

 Therefore, the present invention has been devised to solve such a problem, and the gist of the present invention is to load a large pile cargo 3 on a pallet that is loaded and unloaded on an aircraft and wrapped in a net. At an airport facility that uses a pallet loading system that can be demolished by a forklift, it can be lifted on a self-propelled trolley 6 that can be laterally attached to the pallet truck 2 on which the cargo 3 is placed. A workbench 8 on which an operator can ride is provided via a lifter 7, and a roll composed of a group of free rollers 10a supported directly on the workbench 8 in front of and behind the carriage 6. A plurality of sets of roller conveyors 10 are laid, a plurality of skids 5 each having a smaller area than the pallet are placed on the roller conveyors 10, and a skid 5 for loading the skids 5 is mounted on the reverse side of the work table 8. − Clift fore In unloading work vehicle airport pallet for causing to wait click.

【Example】

 The configuration of the present invention will be described in detail with reference to the embodiments shown in the accompanying drawings. 1 is a side view of an embodiment of the present invention, FIG. 2 is a rear view of FIG. 1, and FIG. 3 is a plan view of FIG.

The pallet unloading work vehicle 1 of the present embodiment subdivides the cargo 3 stacked on pallets (not shown) on the dolly 2 used for the pallet loading system at the airport into skids 5. Then, the skid 5 is transferred (this is called a breakdown at the airport), and the skid 5 is loaded on a forklift (not shown). The height of the cargo 3 stacked on this pallet is about 3.7 ^m above the ground, and the size of the pallet is about 3 ^m × 2.4 ^m .

The pallet unloading work vehicle 1 is a forward-reverse self-propelled vehicle with four wheels 4, 4, ... And is a pallet cargo 3 unloaded from an aircraft and placed on a dolly 2. Work is carried out next to the mountain. The work vehicle 1 is provided with two skids 5 arranged side by side, and these skids 5 are sequentially loaded on a forklift (not shown) and carried to a predetermined place.

A hydraulically operated cross-arm lifter 7 is mounted on a dolly 6 of the work vehicle 1, and a work table 8 is mounted on the lifter 7. Therefore, the workbench 8 is moved up and down from the solid line state in FIG. 1 to the broken line state by the lifter 7. The lift amount is about 2.3 ^m .

Although the workbench 8 has a smaller area than the pallet, it is configured with an expandable work floor so that a worker can board the workbench. Further, the workbench 8 has six sets of roller conveyors. Ten are laid. That is, it is divided into front and rear (in the traveling direction of the work vehicle 1, the side provided with the operation stands 9 and 9a is the front. The same applies to the following), and three sets of roller conveyors 10, 10 ... ... is laid out with some exposure. Therefore, the roller conveyor 10 has three rows on the front side and the rear side, and the skids 5 are mounted on the front and rear roller conveyors 10, respectively. Each roller conveyor 10 is composed of a large number of brake-equipped free rollers 10a, 10a, ... Supported in the direction orthogonal to the traveling direction of the work vehicle 1. Therefore, the skid 5 placed on the roller conveyor 10 can be easily moved in the front-rear direction. The skid 5 is placed so that the fork of the forklift can be inserted from the rear side.

At the front end of the work table 8, a handrail 11 with a net is provided in a U shape in a plan view. Further, a handrail 12 is also provided in an L shape at one corner of the rear end of the workbench 8. Therefore, since there is no fence such as a handrail in the front-rear orthogonal direction of the work table 8, that is, on the left and right sides, the operator can easily carry the cargo 3 on the pallet onto the skid 5. Moreover, since there is no enclosure at the rear end, the skid 5 can be easily moved to the fork of the forklift. In FIG. 2, the cargo 3 piled up on the pallet is on the left side of the work vehicle 1, but the same work can be performed on the right side.

On the left and right sides of the worktable 8, auxiliary worktables 13, 13 shown by broken lines in FIGS. 2 and 3 are provided so as to be freely foldable. The auxiliary workbench 13 is extended so that the cargo 3 located far from the work vehicle 1 can be carried on the skid 5.

An operating stand 9 is provided on the workbench 8 for an operator to board the workbench and carry in the cargo 3, and the operation stand 9 is used to lift and lower the workbench 8. I am trying.

The trolley 6 is provided with an operation stand 9a for driving the work vehicle 1, and a roof guard 14 is provided in order to protect the driver. A backrest portion 15 is provided on the guard 14.

A work lamp 16 is erected on the front end of the work table 8 to enable night work. A bumper / collision sensor 17 is provided around the carriage 6.

Next, the operation of this embodiment will be described. A pallet with a pile of cargo 3 unloaded from an aircraft is placed on the dolly 2. The pallet unloading work vehicle 1 is laterally attached to this dolly 2. Two skids 5 are previously mounted on the work vehicle 1. Then, the workbench 8 is raised and the operator removes the vinyl sheet cover and the net covering the cargo 3 on the pallet. Next, the cargo 3 is sequentially retracted from the front side and carried on the skid 5 on the workbench 8 to be loaded. When the cargo 3 is placed on the skid 5 in a predetermined amount, the workbench 8 is lowered. Next, first, the rear skid 5 is moved on the roller conveyor 10 and loaded on the fork of the forklift waiting. Then, the process is repeated until the cargo 3 on the pallet is used up, but in the middle of the process, the auxiliary worktable 13 is used to bring in the cargo 3 far from the workbench 8. The skids 5 may be used in three or more sets.

[0019]

[Effect of device]

 According to the present invention, the cargo piled on the pallet is not directly broken down by the forklift, but rather the cargo is placed on the skid of the workbench which is lifted and lowered, and then the skid is forked. Since it is carried by, even large piles of cargo on pallets can be safely destroyed.

In particular, when the skid carrying the cargo is loaded on the forklift, the skid is moved by the roller conveyor to be loaded. Therefore, even if the forklift cannot move forward, the forklift can be used for light work. It can be loaded on the road. In addition, since a plurality of skids can be raised and lowered by raising and lowering the lifter once, work efficiency is good.
