<p>PURPOSE:To automatically pack bottomed containers at plural levels sequentially so that the containers adjoin to each other at their top, bottom and each side, some containers are in upright position with their openings at the upside and the others are in inverted position with their openings at the underside. CONSTITUTION:Containers are trued up on a supply conveyor 21 so that some container s are put in upright position with their openings at the upside and shown by circles in the drawing and the other containers are put in inverted position with their openings at the underside and shown by x's in the drawing. When it is supposed that the number of rows twice as many as horizontal rows for one level corresponds to one cycle, the rows in the first half of the cycle are located at a first level and the other rows in the second half are located at a second level over the first one. The containers are trued up so that such cycles are repeatedly sequentially provided on the conveyor 2. Before box packing is started, containers for a half cycle of every two longitudinal rows extending from the front end in the direction of supply are removed. Following containers are moved forth by crowding pressure so that they are trued up in the openings resulting from the removal. After that, four rows of containers at the respective levels are put on a movable table 22 in the position of the box packing.</p> |
