<p>PURPOSE:To perform the conveyance and stop of sheet material with a high accuracy even in the case of conveying various kinds of sheet material by extending a high speed travel distance by a conveyor as well as shortening the low speed travel distance, thereby shortening the conveyed travel time of the sheet material to its target stop position. CONSTITUTION:A low speed travel distance from a low speed travel starting position to target stop position of a conveyor 5 is measured, and this low speed travel distance and the set value, as well as a high speed travel distance are inputted into an arithmetic processing unit 11 for operation, and the operated value is added to the high speed travel distance. The high speed travel distance by the conveyor 5 is thereby extended, as well as the low speed travel distance by the conveyor 5 is shortened, and the conveyed travel time of sheet material to its target stop position is repeatedly controlled to be shortened.</p> |
