2. Description of the Related Art When the working direction of a cargo-handling object transported to a factory or warehouse differs from the working direction of the cargo-handling work means of the factory or warehouse depending on the vehicle or the like, the cargo-handling means is provided with a turning function or a vehicle. It is necessary to align the direction of the with the direction of the cargo handling means. For example, as shown in FIG. 1, when loading or unloading a coil-shaped or tubular transportation object (hereinafter referred to as a cargo) 2 transported by a vehicle 1 such as a self-loading vehicle to a factory or a warehouse, a hole of the cargo 2 is formed. When the direction of h is different from the lifting direction of the cargo handling means 3 such as a crane hook installed in a factory or warehouse, the cargo handling means 3 cannot load and unload the load 2. Therefore, it is necessary to provide the cargo handling means 3 with a turning function or to align the direction of the vehicle 1 with the direction of the cargo handling means 3.

However, attaching a turning device to the cargo handling means 3 requires a large amount of equipment cost, and the turning device has a large weight, which makes the center of gravity of the load unstable and poses a safety problem. On the other hand, it is extremely difficult to change the direction of the vehicle 1 in a factory or a warehouse because it requires a turning space for the vehicle 1.

When a load 2 loaded as shown in FIG. 2 is loaded and unloaded by a lift truck instead of a crane, the arms of the lift truck can be inserted only into the holes h of the load 2 loaded at the rear of the vehicle 1. Therefore, it is not possible to load and unload all the loads 2.

DISCLOSURE OF THE INVENTION The present invention relates to a case in which a work direction of a load and a work direction of a cargo handling means are different when a load such as a self-loading vehicle is unloaded to a factory or a warehouse. Also, it is an object of the present invention to efficiently load and unload cargo without providing the cargo handling means with a turning function or matching the direction of the vehicle with the direction of the cargo handling means.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems by making a pallet rotatable while a load is loaded. The gist of the invention is to rotate a pallet and an upper surface of the pedestal. It is characterized in that the pallet is constituted by a swivel pallet which is attached so as to be possible.

[0007]

The pallet according to the present invention has a plurality of swiveling pallets 5 (3 in the figure) on the upper surface of the gantry 4 as shown in the side view of FIG.
Individual pieces) are rotatably supported by the shaft 6. The pallet 7 is loaded on the vehicle 1 as shown in FIG. 4, and the swivel pallet 5 is loaded with, for example, a coiled or tubular load 2 in the lateral direction.

On the other hand, a C-type hook 9 is vertically attached to the overhead traveling type crane 8 installed in the warehouse shown in FIG. Therefore, the load 2 of the vehicle 1 shown in FIG.
Cannot be loaded and unloaded as it is.

Therefore, when the swivel pallet 5 is swung 90 ° about the shaft 6, the load 2 is oriented in the vertical direction as shown in FIG. 5, so that the load 2 can be easily unloaded by the C-shaped hook 9. it can.

EXAMPLES The present invention will be described in detail below with reference to an example in which a coiled steel material is loaded into a warehouse as a load using the pallet of the present invention. FIG. 6 shows a front view of the pallet. Foot members 10 are attached to the left and right sides of the gantry 4, and shafts 6 are attached to the upper surface at three locations in the longitudinal direction as shown in the side view of FIG. A bearing 11 attached to the lower surface of the center of gravity of the swivel pallet 5 is fitted to the shaft 6 as shown in the enlarged view of FIG. 7, and the swivel pallet 5 is centered around the shaft 6 as shown in the plan view of FIG. The trajectory of the broken line can be turned. A gap S is provided between the turning pallets 5 so that the turning pallets 5 do not collide with the adjacent turning pallets 5 when turning.

As shown in FIG. 7, a stopper member 12 for preventing the movement of the load is attached to the upper surface of the swivel pallet 5, and four casters 13 (only two are shown) are attached to the lower surface. Has been. The casters 13 are supported by arcuate rails 14 attached to the upper surface of the pedestal 4. An arcuate gear 15 is attached to the lower surface of the swivel pallet 5, and a gear shaft 17 of a motor 16 attached to the upper surface of the gantry 4 meshes with the arcuate gear 15. The rotating pallet 5 is driven by the motor 16 to rotate the shaft 6
It is possible to drive to rotate around.

Reference numeral 18 denotes a pair of upper and lower stoppers attached to the rotating pallet 5 and the gantry 4 in order to stop the rotating of the rotating pallet 5. The attachment position of the stopper 18 is on a line with an angle of 90 ° formed by the two lines A and B passing through the turning axis O of the turning pallet 5 shown in FIG. 8, and only one pair is shown in the drawing.

Next, a method of using the pallet 7 will be described. The pallet 7 is loaded on a vehicle (self-loading vehicle) 1 as shown in FIG. 4, and three swivel pallets 5 are loaded with a coiled or tubular load 2 in a lateral direction. On the other hand, a C-type hook 9 is vertically attached to the overhead traveling type crane 8 installed in the warehouse shown in FIG. Therefore, the load 2 of the vehicle 1 shown in FIG.
Cannot be loaded and unloaded as it is.

Therefore, electric power is supplied to the motor 16 shown in FIG. 8 to rotate the three rotary pallets 5 by 90 ° and stop them by the stopper 18. As a result, the cargo 2 is turned sideways as shown in FIG. The sideways load 2 can be efficiently loaded and unloaded by the C-shaped hook 9.

On the other hand, after the load 1 is loaded on the vehicle 1 and the pallet 7 is unloaded from the vehicle by the lifting device (not shown) attached to the vehicle 1, the pallet 7 is unloaded. 2 can also be carried out by a lift truck.

In the embodiment, although the example of the coiled steel material is shown as the load 2, the load 2 is applied to a long material such as a long material in which the suspending direction of the cargo handling means is limited. Further, although four casters 13 are attached, at least three or more may be attached. Furthermore, three swivel pallets 5 are attached to the gantry 4, but only one may be attached. Also, palette 7
To load and unload the vehicle 1 from the vehicle 1
Although 0 is attached, when loading and unloading the pallet 7 with a forklift, protrusions (not shown) for fork engagement may be attached to the left and right outer sides of the gantry 4 instead of the foot member 10. The foot member 10 may not be attached unless the foot member 10 is unloaded from the vehicle. Further, although the rotating pallet 5 is driven by the motor 16, it may be driven manually or by a lift truck. The turning pallet 5 may be turned immediately after the load 2 is loaded on the vehicle 1.

[0017]

According to the pallet of the present invention, since the swivel pallet is rotatably mounted on the upper surface of the pedestal, the load loaded on the pallet can be swung. Therefore, even if the working direction of the cargo is different from the working direction of the cargo handling means in the destination factory or warehouse, the cargo can be turned to match the direction of the cargo with the cargo handling means. As a result, it is possible to efficiently load and unload cargo without the need for a turning device for cargo handling means and a turning space for vehicles in a factory or a warehouse, which have been conventionally required.
