A device, characterized in that it comprises a pusher for pressing the said packing article which is transferred to the second accumulation conveyor in the direction of the guide member.

[0009]

In the above structure, the packaged article is placed on the first accumulation conveyor, transferred, and then delivered to the second accumulation conveyor. The number of pieces delivered to the second accumulator is measured, and when the number reaches the predetermined number, a movable stopper is placed between the first accumulator and the second accumulator to package the article to the second accumulator. Regulate the sending of.

When a set number of packing boxes are arranged on the second accumulation conveyor in a state of being hooked by fixed stoppers, the back surface of each packing is pressed by a pusher. Then, each package is pressed against one side of the second accumulation conveyor and placed on the guide member extending to one side of the second accumulation conveyor.

After that, when the pusher and the movable stopper are returned to the standby position, the next package is sent to the second accumulation conveyor, and the package is moved toward the guide member by the pusher in the same procedure as described above. Press. Then, the previously packaged item is pressed by the current packaged item, and both the packaged items are placed on the guide member.
