Therefore, there is an excellent effect that the boxing work can be performed efficiently at low cost.

Further, it is possible to count the articles supplied from the count conveyor individually and form the article unit row so as to have a length corresponding to the width dimension of the box.

Further, the count conveyor constituting the article unit row forming means is one in which a plurality of groove-shaped partitioning pieces configured to partition the articles one by one are connected, and such a counting conveyor is connected via a connecting plate. Since the flat belt conveyor is connected to the counter conveyor, the articles conveyed by the count conveyor are placed on the communication plate by the rear wall of each section of the count conveyor (the rear section wall surface in the traveling direction of the count conveyor). It is pushed out while being corrected to a posture that is smooth and orthogonal to the traveling direction. As a result, the article rolls into the flat belt conveyor in a regular posture orthogonal to the conveying direction, and the flat belt conveyor conveys the article to a predetermined position while maintaining the proper posture. Therefore, even if the cross-section of the article is not a perfect circle or the article has a different weight balance between the front end portion and the rear end portion, such as a packaging tube, all the articles are arranged in a correct posture without disturbing one thread. Can be formed.

Moreover, since the article is conveyed by the flat belt conveyor, the article unit row can be formed without rolling or sliding the article itself over a long distance. Therefore, it is possible to prevent the outer surface of the article from being scratched or the print from peeling off.

Still further, since the article laminate filling means for extruding the article laminate from the article laminate forming means all at once and filling the box in a lump at the same time is provided below the article unit row extruding means, After the formation, the article laminate is immediately batch-filled in the box, and after the batch-filling, the article laminate forming means can be returned to the position of the article unit row extrusion means by only slightly raising. Therefore, the working time can be shortened.
