Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a schematic view showing a component loading system for a vehicle according to the present invention. Here, the description of the configuration of the general vehicle component loading system will be omitted, and only the configuration according to the features of the present invention will be described.

Referring to the drawings, the vehicle component loading system according to the present invention includes a storage 40 in which a plurality of pallets 30 on which a predetermined part of the vehicle, for example, the small part 11 of the vehicle body, is loaded and are rotated at a predetermined angle, If there is a part 11 on the pallet 30, an ejector device 50 installed on the bottom of the storage 40 to be lifted and moved to load the part 11 and installed on the ejector device 50 may include a pallet ( 30) is configured to include a component sensor 60 for determining the state of loading of the component (11).

As shown in the detailed view of FIGS. 2 and 3, the eject device 50 includes an eject 51 loaded with a component 11 mounted thereon, and an elevating unit 51 capable of elevating the ejecting unit 51. It is configured to include a shuttle (52) for mounting and lifting the component (11), and a latch (53) installed on one side of the eject (51) to load the component (11) in the eject (51).

The storage 40 is provided to rotate about 270 degrees.

In addition, according to the signal of the component sensor 60, when receiving a signal without the component 11, there is provided an alarm device for warning to detect this, the alarm device 70 is made of any one of an alarm light or a bell. .

Referring to the operation of the vehicle component loading system according to the present invention having the configuration as described above are as follows. Here, the description of the operation of the general vehicle component loading system will be omitted, and only the operation according to the features of the present invention will be described.

Referring back to the drawings, the stacking of the components 11 is carried out by the worker about 25 tanks (EA) for each storage 40 in the pallet 30. At this time, when there is no component 11 in the storage 40 or pallet 30, the component sensor 60 is detected and the alarm device 70 is operated, and receives the vehicle model from the vehicle model monitor (not shown) of the vehicle body production system. Storage 40 is rotated.

In more detail, the upper latch 53 provided on one side of the eject device 50 is advanced, and the lower latch 53 moves backward so as to load the component 11 into the eject 51 one by one. . At this time, the ejecting condition is necessarily elevated.

The eject 51 is lowered by receiving the component 11 in an elevated state. At this time, the component sensor 60 detects the presence or absence of a component.

Subsequently, the shuttle 52 confirms the ejection of the ejection 51 and then ascends the front process, and the shuttle 52 advances one process in the raised state, and then descends and retracts to its original position.

And after confirming the vehicle model, the robot 80 picks up the component 11 and moves to the next process.

As shown in the flowchart of FIG. 4 showing this in more detail, first, the parts 11 are taken out from the pallet 30 for each vehicle type specification, and then the parts 11 are loaded on the mounting table.

The vehicle model and specification are then output from the production sequence system and input to the operation panel (or control panel). (Step 120)

In the production sequence system, the vehicle model is selected according to the specification of the vehicle model and the specification output, and the storage 40 is rotated (step 130).

Subsequently, after confirming the vehicle model and specification, if there is a mismatch, a warning light and a bell of the alarm device 70 are activated. At this time, in case of vehicle mismatch, the sequence worker checks and corrects it (step 140).

After the component 11 is in the storage 40 in step 140 and the specification is confirmed, the eject 51 is raised (step 150).

The rise of the eject 51 is confirmed, and the latch 53 on one side is advanced to load one piece of the component 11 into the eject 51 (step 160).

In addition, the latch 53 is moved backward so that one part 11 is lowered while the next part 11 is prepared.

Subsequently, after confirming the loading of the component 11 on the eject 51, the eject 51 is lowered (step 180).

And after confirming the component 11, the shuttle 52 raises and prepares for one process movement. At this time, the whole process rises simultaneously (step 190).

The shuttle 52 then advances to move the component 11 one process. At this point, the entire process moves (step 200).

Furthermore, after the process of moving the component 11 one step, the shuttle 52 descends. In this case, the pitch is shifted by one pitch (step 210).

Then, after moving the component 11, the shuttle 52 is retracted to its original position. At this time, there is no component 11 in the shuttle 52 (step 220).

Subsequently, after comparing and confirming the vehicle model and the parts 11, the robot 80 starts up. At this time, when the vehicle mismatch occurs, the alarm device 70 is activated. (Step 230) After the component 11 is loaded, the body welding operation is performed.

As described above, the vehicle component loading system according to the present invention has the following effects.

When the small parts are stacked, the latch 53 (or stopper) 12 (see FIG. 1), etc. is not used as in the related art, and thus easy to load, and a large amount of parts can be loaded. It is easy to apply multiple models even in space And by applying the shuttle 52 in place of the overhead loader 20 of the prior art, the structure of the equipment is simple and can be applied to multi-vehicle production in a small space.

As a result, the body assembly line configuration can be compactly established, and is suitable for small quantity production of a multi-vehicle model.

In addition, the flow of logistics can be simplified, production preparation period can be shortened, and facility investment cost can be reduced.
