Description

  More specifically, the present invention relates to a loaded material loading apparatus and a loaded material loading method using the same, and more particularly, even when the loaded material is a heavy material, the heavy material is automatically loaded on the truck bed in a short time. The present invention relates to a transported article loading device having a simple and inexpensive structure and a transported article loading method using the same.

  Conventionally, in general, at a coil material processing center, for example, as shown in FIG. 16, a coil material C as a product processed in a production line 150 is transferred to a product store 151 by a line crane 105 that is operated wirelessly. Stored. Of the coil material C stored in the product store 151, the coil material C to be shipped according to the truck arriving at the processing center is transferred to a predetermined collection place by a collection crane 106 operated by a boarding worker. Then, the coil material C transferred to the pickup location 152 is loaded on the truck bed 102 located at the predetermined loading position L via the loading crane 153 operated by the boarding worker. It is known that

  However, in the above conventional loading work, at least two crane operating workers and four slinging workers are required for each of the loading crane 106 and the loading crane 153, and a large number of work Needed a worker. Furthermore, a series of loading operations takes time. For example, it takes about 1 from when a truck arrives at a processing center to completion of loading operations of 5 to 10 coil materials collected. It took time. Further, there is a possibility that the coil crane and the loading crane 153 interfere with each other and the coil material may be damaged, and a skilled crane operator is required. Furthermore, since the coil material is directly transported by the loading crane 106 and the loading crane 153, there is a possibility that loading or sorting is wrong.

Thus, as a conventional loading device for solving the above-described problem, there is known a device that automatically loads a conveyed product on a truck bed using a pallet (see, for example, Patent Documents 1 and 2). By using the pallet in this way, a pallet on which a conveyed product is loaded can be prepared in advance for each loading order, and loading errors and sorting errors can be prevented.
And the said patent document 1 is disclosing the loading apparatus which provides the load transfer means which consists of the several guide roller 4 for guiding a conveyed product in the front end side of the conveyor 2. FIG.
Further, Patent Document 2 discloses a loading device that can adjust the height level and width direction position of a conveyor according to a truck bed.

However, in Patent Documents 1 and 2, since the pallet on the conveyor is sent out to the truck bed by driving the conveyor, the transported object loaded on the pallet is heavy (for example, the transported object is 100 kg). When the steel coil material is about 20 to about 20 tons), there is a risk that the load cannot be loaded or the load collapses due to interference (frictional contact) between the pallet and the floor surface of the truck bed. Moreover, when loading a heavy transporter, it is necessary to use a conveyor having a relatively large driving force, or to use another loading assist mechanism or the like in addition to the conveyor.
In addition, when loading a heavy transported object, the suspension of the truck sinks in the middle of transporting the transported object on the conveyor, and the conveyor tilts to a state where the truck bed side becomes low, and the transported object is There is a risk of slipping on the conveyor, damage, and failure to load at the correct loading position. However, Patent Document 1 does not provide any countermeasure against the sinking of the suspension during the conveyance of the conveyed product.
In addition, in the conventional loading apparatus, it is known that the inclination angle of the conveyor is changed according to the vertical displacement amount of the front end portion of the conveyor (see, for example, Patent Documents 3 and 4). As a preparatory work before loading an object, the purpose is to enable the expansion and contraction of the conveyor and the movement of the carriage to be performed smoothly, which is different from the countermeasure against the sinking of the suspension during the transfer of the conveyed object as described above.
