Description

DEVICE FOR ROTATING RACKS FOR AN AUTOMOBILE ASSEMBLING LINE

The present invention relates to a rack automatic rotating apparatus of an automobile assembly line, and more particularly, by reducing the supply time by preventing the assembly of erroneous specs by improving the productivity by rotating the rack of the corresponding vehicle according to the order of each process. The present invention relates to a rack automatic rotating apparatus of an automobile assembly line.

Generally, a car is divided into a body and a chassis, and the body is a part of the car, which stores and transports the engine compartment and the engine room where the engine is installed. It can be divided into a trunk compartment.

In order to combine the body into one assembly, each of the parts, such as the under body, the side assembly, and the roof panel, is transported to the main welding jig, and then welded and joined to the main welding process. In this process, a rack is used to load various panels such as side body panels constituting the side assembly and carry them to the assembly process.

In general, when carrying a body panel, the body panel is mounted on a pedestal and moved. The body panel mounted on the rack's pedestal is transported by a forklift or the like to be seated on the support pin, and then assembled and transported by the gripper of the 8-axis robot to the engaged position. In this case, as shown in FIG. 1, the worker removes and assembles one by one from a rack in which body panels of various sizes are loaded according to vehicle types.

1 is a plan view schematically showing a rack supply state of a vehicle assembly line according to the prior art. According to the prior art, the operator places the first to fourth racks 30, 32, 34, and 36 according to each specification in order to assemble the body panel in the first process 38. Next, after removing the body panel of the corresponding specification from the rack (30, 32, 34, 36) and loading it, the body assembly is transferred to the next second process.

In a conventional automobile assembly line having such a configuration, the worker's moving distance is long, so that the working time is increased and the fatigue is increased. In addition, since the operator must take out the body panel from the rack after confirming the car model one by one, there is a problem in that the mis-specification is reduced to reduce the productivity.

The present invention is to solve these problems, the object is to input the corresponding vehicle type for each work order, and then control the rack to stop in front of the work process by the rotary plate automatically rotated in this order, working time It is to provide a rack auto rotating device of the automobile assembly line that can improve the productivity by shortening and preventing the assembly of the mis-specification.

The object of the present invention described above is to rotate the rotating plate on which the plurality of racks on which the body panel is mounted is seated, the rotating shaft supporting the rotating plate, and the rotating shaft by an external power source, and the rack on the rotating plate according to the process sequence. It is achieved by a rack automatic rotating device of an automobile assembly line, characterized in that the motor is configured to be positioned in front of the work process.

Hereinafter, with reference to the accompanying drawings will be described with respect to the rack automatic rotating apparatus of the vehicle assembly line according to a preferred embodiment of the present invention.

Figure 2 is a plan view schematically showing a rack automatic rotating apparatus of the vehicle assembly line according to the invention, the same configuration as the conventional structure described in Figure 1 is denoted by the same reference numerals.

As shown here, in the preferred embodiment of the present invention, the rotary plate 22 is adopted to control the rack on which the body panel of the corresponding specification is loaded according to the input work process to stop in front of the work process. The rotating plate 22 is mounted with a plurality of racks 10, 12, 14, 16 on which body panels of different specifications are mounted.

Accordingly, when the rotating plate 22 is rotated according to an electrical signal determined for each process transmitted from the control unit, one of the racks 10, 12, 14, 16 seated on the rotating plate 22 according to this process 14 ) Will stop exactly in front of the first process (18), at which time the operator can take out the body panel loaded on the rack 14 and assemble. After assembly of the body panel, the body assembly is transferred to the next second process 20.

3 is a front view schematically showing the rack automatic rotating apparatus of the vehicle assembly line according to the present invention. According to the overall configuration of the rack automatic rotating apparatus according to the present invention, the rotating plate 22 on which the plurality of racks 10, 12, 14, and 16 on which the body panel is mounted is seated, and the rotating plate 22 A motor for controlling the rack on the rotating plate 22 so that the rack on the rotating plate 22 is correctly positioned in front of the working process by loading the rotating shaft 24 supported by the rotating shaft 24 and the externally supplied power. It consists of 26.

Here, in the preferred embodiment of the present invention to rotate the rotary plate 22 has been illustrated a method of rotating the rotary plate 22 via the rotary shaft 24 by the motor 26, according to the work order Any type of rack can be used as long as it can be controlled to be located in front of the work process. The motor 26 is rotated in the order transmitted from the control unit (not shown) to rotate the rotating plate 22 so that the rack corresponding to each process is accurately positioned before the work process.

According to the rack rotating apparatus of the present invention described above, by inputting the vehicle model for each work order, by controlling the rack to stop in front of the work process by the rotary plate automatically rotated in this order, the work time is shortened It is easy to cope with the addition of the specification and prevents the assembly of incorrect specifications, thereby improving productivity.
