Abstract

PURPOSE:To enable a member on rollers to be placed in a specified position through automatic correction of a position, by a method wherein the rollers, the rotation centers of which cross each other, are dispersedly situated. CONSTITUTION:The given number of plates 7 is conveyed to a member loading part 3 by means of a belt conveyor 6. In this case, since photoelectric switches 101a-104b all secure their respective optical passes, the switches are brought into an ON-state, rollers 8a and 8b are all rotated clockwise. Thus, even when the plate 7 is transferred from a conveyance part 2 to the member loading part 3, the plates are moved forward in a state in that placing orientation on the the conveyance part 2 is maintained. When the plate 7 is conveyed in a state to be inclined, the optical pass of the photoelectric switch is shut off and brought into an OFF-state, inclination of the plate 7 is detected, and the rotation direction of each of the rollers 8a and 8b is switched. This constitution corrects inclination of the plate 7 and a position in a direction Y-Y.

For example, if the plate 7 is conveyed tilted as shown by the two-dot chain line A1 in FIG. 4, the front edge of the plate 7 on the upper and lower sides in the figure reaches the photoelectric switch 102a. Therefore, the optical path of the charging switch 102a is blocked and the charging switch 102a is turned off. At this time, the charging switches 101a and 101b are turned on to secure the optical path, and based on these 0N-OFF signals, the combiator detects that the plate 7 is tilted and switches the rotation direction of each roller 8a and 8b. . That is, two sets of rollers S located in zone B2 shown in FIG.
For a and 8b, each roller 8a or the top left rotation in Fig. 3 (

, and when the plate 7 comes to the position shown by the two-dot chain line A0 in FIG.
a, 104a are turned off as the optical path is blocked, and each charging switch 1011, 102b, 103b, 1041) is turned on with the optical path secured, and it is detected whether the plate material 7 is placed at the correct placement position. The rollers 8a and 8b all stop.

Thereafter, the magnetic separator 11 retreats to the front edge of the plate material 7 and comes into contact with it, separating each plate material 7. Then, the lifting head 15 of the workpiece feeding robot 4 descends and suction-supports the uppermost plate 7 with the suction part 17, the lifting body 15 rises, and the slider 14 moves forward along the spline shaft 13. The plate material 7 is pressed (automatically co-supplied to the plate 5).

In this way, the loaded plate material 7 is always placed at a fixed position on the member placement part 3, so that the plate material 7 can always be set correctly in the working part (not shown) of the press processing machine 5. can.

Further, in the member position correction device 1 of the above embodiment, since the member mounting section 3 is arranged at the terminal end of the belt conveyor 6, the installation space for the conveying system for the plate material 7 can be reduced.
