An article boxing apparatus according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of a mechanical caser provided with an article boxing device. The article (work) P to be packed is, for example, a flexible package that contains a large number of paper diapers. The articles P have a rectangular parallelepiped shape having the smallest bottom surface S and top surface T among the six outer peripheral surfaces, and the four articles P are arranged in 2 columns × 2 rows with the bottom surface S facing down. H.

  The article P is placed on the supply conveyor 11 in a fall state with the bottom surface S facing the downstream side in the transport direction (arrow X), and is supplied to the article boxing device. An accumulation table 12 of an article boxing device is provided at the most downstream position of the supply conveyor 11. The accumulation table 12 extends to the vicinity of the transfer conveyor 13 provided in parallel to the supply conveyor 11. The height position of the accumulation table 12 is lower than that of the supply conveyor 11, and when the article P is transferred from the supply conveyor 11 to the accumulation table 12, the article P stands up by rotating 90 ° around a horizontal axis parallel to the accumulation table 12. Is placed on the stacking table 12 facing down.

  A first accumulation pusher 14 is provided below the supply conveyor 11 and in the vicinity of the accumulation table 12. A fall prevention guide 15 is disposed on the accumulation table 12 so as to face the first accumulation pusher 14. Is done. The accumulation pusher 14 can reciprocate along the conveying direction of the supply conveyor 11. The guide 15 is provided at the edge of the stacking table 12 on the side far from the supply conveyor 11 and can reciprocate along the transport direction like the stacking pusher 14. When the first article P is placed on the accumulation table 12, the first accumulation pusher 14 advances to the guide 15 side at the protruding position to bring the article P into contact with the guide 15. Thereafter, the first integrated pusher 14 and the guide 15 are retracted in a direction away from each other. When the second article P is placed on the accumulation table 12, the first accumulation pusher 14 presses the article P, whereby both articles P move to the guide 15 side, The eye article P contacts the guide 15. As a result, the two articles P are combined into one article group.

  A second accumulation pusher 16 is provided above the accumulation table 12. The second stacking pusher 16 can reciprocate along the guide 15, and transports a group of articles toward a chuck device 21 provided above the stacking table 12 and on the side of the transport conveyor 13. As will be described later, the chuck device 21 holds two article groups together, transfers them to the packaging box H on the conveyor 13, and inserts them into the packaging box H. That is, four articles P are accommodated in one packaging box H in the form of “2 columns × 2 rows” and are transported to the next process by the transport conveyor 13.

  FIG. 2 shows the chuck device 21. The chuck device 21 is supported by a fixed frame 22, and reciprocates between the upper side of the stacking table 12 and the upper side of the transfer conveyor 13 to transfer the articles P from the stacking table 12 to the transfer conveyor 13. Further, the chuck device 21 is movable up and down with respect to the fixed frame 22, descends on the transport conveyor 13, and accommodates the transported article P in the packaging box H.

  A pair of holding members 24 and 25 and a partition member 26 are attached to the support mechanism 23 of the chuck device 21. The pair of holding members 24 and 25 support the outer surfaces of these article groups in order to transfer the two article groups to the packaging box H. The holding members 24 and 25 are connected to link mechanisms 28 and 29 attached to the guide member 27 of the support mechanism 23 and can be opened and closed. The partition member 26 is located near the center of the guide member 27 and is provided so as to be interposed between two groups of articles held by the holding members 24 and 25. Further, the partition member 26 can advance and retreat in a direction perpendicular to the transfer direction of the chuck device 21 (that is, the vertical direction), and can move along the transfer direction.

The operation of this embodiment will be described with reference to FIG.
The group of articles is pushed by the second accumulation pusher 16 and transferred along the arrow Y to below the chuck device 21. At this time, the holding member 24 located rearward in the transfer direction (on the right side in FIG. 3) rotates counterclockwise as shown in FIG. 3A and is located at a retracted position that does not interfere with the supplied article group. doing. The other holding member 25 is in the holding position with the vertical downward direction. Similarly to the holding member 24, the partition member 26 is retracted to the raised position. Therefore, the article group passes through the lower side of the holding member 24 and the partition member 26 and is transferred to a position where the article group contacts the holding member 25.

  Next, after the partition member 26 is lowered as indicated by the symbol X in FIG. 3B, it is displaced toward the holding member 25 as indicated by the symbol Z and comes into contact with the rear side surface of the article group. Simultaneously with this operation, the next group of articles is pushed by the second stacking pusher 16 and supplied below the chuck device 21. When this group of articles comes into contact with the partition member 26 (FIG. 3C), the holding member 24 moves downward to support the rear side surface of the rear group of articles (FIG. 3D).

  Thereafter, the second accumulation pusher 16 returns to the original position, and the chuck device 21 rises to lift the two sets of articles. Then, the chuck device 21 transfers the two sets of articles by the pair of holding members 24 and 25 and the partition member 26 to the position just above the packaging box H placed on the transport conveyor 13, and is indicated by a broken line in FIG. As shown, it is lowered and inserted into the packaging box H. Next, the holding members 24 and 25 are released to be separated from the group of articles, and are lifted to come out of the packaging box H and return to the stacking table 12.

  By repeating such an operation, the chuck device 21 stores the two sets of articles received from the supply conveyor 11 in the packaging box H on the transport conveyor 13. The conveyor 13 is stationary while the group of articles is accommodated in the packaging box H. However, when the accommodating operation is completed, the conveying conveyor 13 conveys the packaging box H downstream by a predetermined amount and supplies it to the next step.

  The partition member 26 is made of a metal plate having a high friction coefficient, for example. Specifically, the partition member 26 is sufficient to stably hold the article group in cooperation with the holding members 24 and 25 when the article group is transferred from the stacking table 12 to the transport conveyor 13. As long as it has a coefficient of friction, mechanical strength is not required. That is, the partition member 26 is a thin plate member, and it is not necessary to change the size of the packaging box H by providing the partition member 26, and the conventional packaging box H can be used as it is.

  As described above, the chuck device 21 according to the present embodiment stably transports a collection of a group of articles composed of a plurality of flexible articles P arranged in a direction orthogonal to the transfer direction in a group along the transfer direction. be able to. That is, in the transfer operation, each article P is supported by the partition member 26, so that the article group does not collapse from the center and fall. Therefore, the operation of accommodating the articles in the packaging box H can be executed reliably and stably, and the efficiency of the packaging operation of the flexible articles is improved.

  In this embodiment, the configuration of the group of articles packed in the box is “2 columns × 2 rows”, but the present invention is not limited to this, and may be, for example, “2 columns × 3 rows”. It can be selected according to. The partition member 26 is not limited to a single member, and a plurality of partition members 26 may be provided.
