Double Registration Prevention
Cnv_QueReject avoids registering the same part doubly. If Cnv_QueReject value is not changed from the default (0 mm), the robot may perform the pickup motion at the position where the part is not placed, since the same part is registered to the queue several times.
Cnv_QueReject can be set by using the command or by following the steps below.
Select [Tools]-[Conveyor Tracking].
Click the conveyor you want to configure and select [Preferences].
Set the value to [Reject Distance].
Click the [Apply] button.
KEY POINTS
If “Cnv_QueReject” is used in the program, the value set for “Cnv_QueReject” will be used instead of the value set in the above step.
When the same workpiece is imaged multiple times as shown in the figure below, the moved Work1 queue position which from the initially registered Work1 will not exactly match the coordinates of the newly registered Work1 queue due to the influence of the camera and conveyor etc. To prevent the same workpiece from being registered in the queue more than once, it is recommended to enter a value similar to the workpiece size as the double registration prevention distance.
