The vacuum cup 20 is a cup-shaped member made of a rubber material, and is connected to an air pipe (not shown) through which air flows in and out, and has a structure for vacuum-adsorbing the panel P.

The moving part 30 is to move the position of the air cylinder 10 as necessary, the housing 31 is installed vertically on the upper portion of the equipment, the servo motor 32 is installed vertically in the housing 31 , A reduction gear group 33 connected to the rotation shaft of the servomotor 32, a shaft member 34 connected to an output shaft of the reduction gear group 33 and rotatably installed on the lower end of the housing 31, the shaft It includes a connecting bar 35 connecting the shaft member 34 and the air cylinder 10 so as to be spaced apart from the member 34 by a predetermined distance.

Accordingly, when the servo motor 32 is driven, the shaft member 34 is rotated through the reduction gear group 33, and the air cylinder 10, which is spaced a predetermined distance from the center of the shaft member 34, moves the shaft member 34. By moving to the center is to change the position of the vacuum cup (20).

The connecting bar 35 is to separate the air cylinder 10 by a predetermined distance so that the air cylinder 10 is not placed on the same axis with respect to the center of the shaft member 34. Depending on the length of the connection bar 35, the rotation radius of the air cylinder 10, that is, the movable range of the vacuum cup 20 is changed. The length of the connecting bar 35 is not particularly limited.

Unexplained reference numeral 36 is a bearing block installed between the housing 31 and the output shaft of the reduction gear group 33.

As the air cylinder 10 is supported by the connection bar 35, the bearing force may be weakened when the air cylinder 10 moves or lifts the panel.

This device has a structure for supporting the upper end of the air cylinder 10 in order to reinforce the bearing force of the air cylinder (10).

To this end, the device is connected to the outer side of the housing 31 and the rail member 40 which is installed along the radius of rotation of the air cylinder 10 to the outer peripheral surface of the housing 31, and the air cylinder of the It includes a support bar 41 vertically installed at the top and extending toward the rail member 40, and a rolling roll 42 installed at the tip of the support bar 41 and placed on the rail member 40.

The rail member 40 forms a rail surface on which the rolling rolls 42 are placed by pairing two pairs and the opposite ends of the rail members 40 are bent inward.

As shown in FIG. 2, the rail member 40 has a circular structure along the rotation radius of the air cylinder 10. The rail member 40 is fixedly installed on the housing 31, and is fixedly installed on the outer surface of the housing 31 through a separate support bracket 43.

Rotating shafts are rotatably installed at the upper end of the support bar 41, and rolling rolls 42 are rotatably installed at both ends of the rotating shafts so as to be placed on the rail surfaces of the respective rail members 40.

Hereinafter, the operation of the apparatus will be described with reference to FIGS. 3 and 4.

When a new panel P having a different form from the existing panel is supplied from the panel supply unit, the operator can transfer the panel appropriately by changing the position of the vacuum cup 20 according to the form of the new panel.

First, when a new panel is put into a line, an operator selects a vacuum cup 20 to be driven from among a plurality of vacuum cups 20 provided according to the shape of the panel.

When the vacuum cup 20 is selected, the position of the vacuum cup 20 is set according to the shape or center of gravity of the panel, and the moving angle for each air cylinder for moving each vacuum cup 20 to the corresponding position is calculated.

When the command is executed to each air cylinder 10 through a control panel or the like, the servomotor 32 installed in the housing 31 is controlled to move the air cylinder 10 to the corresponding position.

That is, when the servo motor 32 is driven, the driving force is transmitted through the reduction gear group 33 installed on the rotation shaft of the servo motor 32 to rotate the shaft member 34 installed on the output shaft of the reduction gear group 33.

As the shaft member 34 is rotated, the air cylinder 10, which is connected to the shaft member 34 via the connecting bar 35, moves about the shaft member 34.

Therefore, it is possible to move the vacuum cup 20 installed at the tip of the piston rod 11 of the air cylinder 10 to a desired position.

Figure 4 shows an example of varying the position of the vacuum cup 20 for conveying the fender panel of the vehicle. As shown, the vacuum cup 20 extending out of the fender panel and the vacuum cup 20 spanning the edge of the fender panel are properly moved into the fender panel as the air cylinder 10 moves as described above. Therefore, even if it is arranged with only a smaller number of vacuum cups 20 than in the prior art will be able to properly transfer a variety of panels.

In this case, the air cylinder 10 is supported by the rail member 40 via the connection bar 35 to secure a supporting force in the process of lifting and lowering the panel. The support bar 41 has a structure in which the rolling roll 42 installed at the tip is rolled along the rail member 40 so that smooth movement is possible when the air cylinder 10 moves.

When the vacuum cup 20 moves to the corrected position as described above, the driving of the servomotor 32 is stopped and a current is applied to the electromagnet 50 to operate the electromagnet 50.

As the electromagnet 50 is operated, magnetic force is applied to the rail member 40 so that the rolling roll 42 placed on the rail member 40 is attached to the rail member 40. Accordingly, each air cylinder 10 is fixed at the corrected position. As such, when the position of the vacuum cup 20 is changed according to the movement of the air cylinder 10, the corresponding data is stored on the facility and continues to be applied to the panel.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
