A method for delivering a plurality of conveyed objects (F2) with aligning the conveyed objects (F2) in a lateral direction (B) with respect to a traveling direction (A) by an arranging conveyor system , the conveyed objects (F2) being supplied in a plurality of lines in the traveling direction (A) without being aligned in the lateral direction (B), the arranging conveyor system having, for each of the plurality of lines, an outlet conveyor , at least one intermediate conveyor disposed adjacent to and upstream of the outlet conveyor , and a transferring/discharging conveyor disposed adjacent to and upstream of the intermediate conveyor , comprising: stopping the conveyed object (F21) at a stop position on the outlet conveyer in each of the plurality of lines to align the conveyed objects (F21) in the lateral direction (B) (S10); setting a delivering interval to a predetermined value for delivering the conveyed objects (F21) from the outlet conveyor with aligning the conveyed objects (F21) with each other in the lateral direction (B); determining whether the delivering interval has passed from a previous delivering action (S41); characterized in that the method further comprises the following steps: delivering the conveyed objects (F21) in all of the plurality of lines downstream from the outlet conveyers when the delivering interval has passed from the previous delivering action and the conveyed objects (F21) in all of the plurality of lines are present at the stop positions on the outlet conveyers (S42, S43); and discharging the conveyed object (F23) outside of the arranging conveyor system , which conveyed object (F23) is present in a specific line of the plurality of lines at a stop position on the transferring/discharging conveyor , when the delivering interval has not passed from the previous delivering action and a predetermined clog condition in the specific line is fulfilled (S51, S53). stopping the conveyed object (F21) at a stop position on the outlet conveyer in each of the plurality of lines to align the conveyed objects (F21) in the lateral direction (B) (S10); setting a delivering interval to a predetermined value for delivering the conveyed objects (F21) from the outlet conveyor with aligning the conveyed objects (F21) with each other in the lateral direction (B); determining whether the delivering interval has passed from a previous delivering action (S41); characterized in that the method further comprises the following steps: delivering the conveyed objects (F21) in all of the plurality of lines downstream from the outlet conveyers when the delivering interval has passed from the previous delivering action and the conveyed objects (F21) in all of the plurality of lines are present at the stop positions on the outlet conveyers (S42, S43); and discharging the conveyed object (F23) outside of the arranging conveyor system , which conveyed object (F23) is present in a specific line of the plurality of lines at a stop position on the transferring/discharging conveyor , when the delivering interval has not passed from the previous delivering action and a predetermined clog condition in the specific line is fulfilled (S51, S53). delivering the conveyed objects (F21) in all of the plurality of lines downstream from the outlet conveyers when the delivering interval has passed from the previous delivering action and the conveyed objects (F21) in all of the plurality of lines are present at the stop positions on the outlet conveyers (S42, S43); and discharging the conveyed object (F23) outside of the arranging conveyor system , which conveyed object (F23) is present in a specific line of the plurality of lines at a stop position on the transferring/discharging conveyor , when the delivering interval has not passed from the previous delivering action and a predetermined clog condition in the specific line is fulfilled (S51, S53). <EOS>
