Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic container stuffing device.

Conventionally, loading cargo into a container such as a marine container has been carried out manually by placing the cargo on a pallet and using a forklift or the like, thus requiring a driver.

In addition, as a device for automatically stuffing cargo, there is a truck loader a as shown in Figure 1 A, B, C, D, and E, which is a device that connects the loading platform c of truck b and the conveyor d. A moving conveyor f placed on an elevating device e is placed in between, and cargo g for one truck b is loaded onto the moving conveyor f [Figure 1 A and B], and the moving conveyor f carries the cargo g. The truck enters the loading platform c of the truck B with the cargo loaded thereon [Figure 1 C], stops when it reaches the designated position, and then transfers the cargo G onto the loading platform C while moving backwards [Figure 1 D and E].
It is something.

Therefore, in the truck loader a, the movable conveyor f moves with the cargo g placed thereon, so the frame must also be made strong and the diameter of the rollers also becomes large. Therefore, the height of the moving conveyor f increases, and if the container has a roof and its height is limited, the height of the cargo g is the height of the container h minus the height of the moving conveyor f. It cannot be packed, and loading efficiency decreases.
Furthermore, if the height of the moving conveyor f is high, the load may collapse due to the difference in level.

The present invention eliminates the drawbacks of the conventional container stuffing device described above, and provides an automatic container stuffing device that is equipped with a stuffing conveyor unit and a transfer conveyor unit and is dual height adjustable. The cargo is moved from the ground conveyor via the transfer conveyor unit onto the stuffing conveyor unit in the container, and the cargo is placed in the container, without being transported by the stuffing conveyor unit.
The purpose is to provide an automatic cargo stuffing device for containers that has high loading efficiency and is less likely to collapse.

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

FIGS. 2 to 5 show an embodiment of the automatic cargo stuffing device for containers according to the present invention, in which a ground conveyor 1
and sea container 3 placed on container stand 2
A box-shaped automatic cargo stuffing device main body 4 with an open upper surface is disposed between the container and the container so that it can be raised and lowered by a lifter 5. As shown in FIG. 5, a conveyor unit 7 is disposed within the automatic cargo stuffing device main body 4, and a built-in lifter 6 is provided on the inner bottom surface of the automatic cargo stuffing device 4.
The conveyor unit 7 is supported so that the roller conveying surface of the conveyor unit 7 can be raised and lowered by the upper edge of the automatic cargo stuffing device main body 4 and positioned above the upper edge of the automatic cargo stuffing device main body 4. A stuffing conveyor unit 10 having rollers 8 and 9 on the upper and lower surfaces as shown in the figure is placed so that the rollers 9 on the lower surface are in contact with the upper edge of the automatic cargo stuffing device main body 4 to automatically transfer cargo into a container. A stuffing device 11 is configured. In the figure, 12 indicates cargo placed on the ground conveyor 1, and 13 indicates a pallet.

4A, B, C, D, H, and F are diagrams showing each operation sequence of the automatic cargo stuffing device for containers of the present invention, in which the sea container 3 placed on the container platform 2 is placed on the ground. The pallet 13 transported by the conveyor 1 and the cargo 12 on it are automatically packed.

First, the automatic cargo stuffing device main body 4 is raised by the lifter 5, and the upper surface of the main body 4 is leveled with the floor surface of the marine container 3 (FIG. 4A).

The stuffing conveyor unit 10 placed on the main body 4 is moved by its built-in travel drive and moved into the sea container 3 (FIG. 4B).

The transport conveyor unit 7 housed inside the main body 4 is raised by the built-in lifter 6, the rollers on the upper surface of the transport conveyor unit 7 and the rollers on the upper surface of the ground conveyor 1 are aligned, and then the ground conveyor 1 and the rollers on the ground conveyor 1 are leveled. The rollers of the conveyor unit 7 are rotated to transfer the pallet 13 and the cargo 12 thereon onto the conveyor unit 7 (FIG. 4C).

The upper surface of the transport conveyor unit 7 and the upper surface of the rollers 8 of the stuffing conveyor unit 10 contained in the floor surface of the sea container 3 are at the level of the upper surface of the sea container 3.
This may differ due to changes in the thickness of the floor, etc., so the conveyor unit 7 is raised and lowered using the built-in lifter 6 to level them both, and then the rollers of the conveyor unit 7 and the stuffing conveyor unit 10 are rotated. The pallet 13 and the cargo 12 are moved forward and packed into the sea container 3 [Fig. 4 d].

When the cargo 12 reaches the deepest part of the sea container 3, the conveyor unit 7 is lowered so that the roller conveying surface does not protrude above the upper edge of the automatic cargo stuffing device main body 4, and then it runs on the stuffing conveyor unit 10. It is moved backward by the drive device and taken out of the sea container 3. The stuffing conveyor unit 10 has rollers 8 and 9 on the upper and lower surfaces, and when retracting, the lower roller 9 is rotated clockwise as shown in FIG. 3, and the upper roller 8 is rotated so that the cargo 12 Since the stuffing conveyor unit 10 is rotated counterclockwise so as to move forward, the cargo 1 is removed from the sea container 3 while the stuffing conveyor unit 10
2 is stored in the sea container 3 [Figure 4 E].

After the stuffing conveyor unit 10 is removed from the sea container 3, the entire main body 4 is lowered by the lifter 5, and the door of the sea container 3 is closed.

It should be noted that the automatic cargo stuffing device for containers of the present invention is not limited to the above-mentioned embodiments;
It goes without saying that various modifications can be made without departing from the gist of the present invention, such as being applicable not only to marine containers but also to containers in general use.

As described above, according to the automatic cargo stuffing device for containers of the present invention, (1) Since the cargo only moves along with the pallet on the transport conveyor unit and the stuffing conveyor unit, the stuffing of the cargo becomes easy, and There is no need for the stuffing conveyor unit to carry 20 to 30 tons of cargo. Therefore, the stuffing conveyor unit does not need to be sturdy and can be made thin, increasing loading efficiency.

() Double lifters are installed to adjust the height, so even if the level of the container and ground conveyor changes, cargo can be automatically loaded into the container.

() Since the stuffing conveyor unit can be made thinner, cargo collapse due to differences in level is less likely to occur, and the stuffing of cargo into containers can be automated, resulting in labor savings.

() If the automatic container stuffing device of the present invention is used on a trolley, one stuffing device can handle a plurality of containers, increasing cargo handling efficiency.

It exhibits various excellent effects such as.
