[Operation of boxing device]
Next, an example of the operation of the boxing device 100 will be described. This operation is realized by processing of the control device 30.

  First, when the operation is started, the control device 30 controls the alignment conveyor 6 to align a predetermined number of articles W sequentially supplied from the supply conveyor 200 at the alignment position T.

  Next, the control device 30 controls the extrusion device 7 to move the extrusion plate 70 from the retracted position to the advanced position, thereby pushing out the articles W aligned at the alignment position T onto the floor plate 11. Thereby, an article group consisting of a plurality of articles W is placed in an aligned state at the article placement position A, and each article W has both ends in the horizontal direction perpendicular to the alignment direction Y by the extrusion plate 70 and the stopper plate 17. It will be in an aligned state.

  Next, the control device 30 controls the pinching device 8 to advance the pair of holding plates 80 in directions approaching each other. As a result, the article group can be clamped from the alignment direction Y to bring the articles W into close contact with each other.

  Next, the control device 30 controls the pushing device 9 to lower the pushing member 91 having a sucking function so as to come into contact with the upper surface of the pressed article group, and suck the upper surface of the article group. As a result, the article group is held by the pushing member 91.

  Next, the control device 30 controls the floor opening / closing device 10 to drive the pair of floor plates 11 backward to bring the floor plates 11 into an open state. As a result, an opening is formed directly under the article group located at the article placement position A.

  On the other hand, the control device 30 performs an outer box arrangement process in parallel with the above process. In this exterior box arrangement process, the rod body 23a of the restraining device 23 is placed in the advanced position in advance, and the exterior box 110 carried in by the exterior box transport conveyor 22 is stopped at the box stop position U. When the control device 30 receives a box detection signal from the box detection device 25, the control device 30 stops the transfer operation of the outer box transfer conveyor 22, raises the base 24, and moves the outer box 110 at the box stop position U to the boxing position P. To be located.

  And after making the floorboard 11 into an open state as mentioned above, the control device 30 controls the pushing device 9 to lower the pushing member 91 adsorbing the group of items, so that the outer box at the packing position P is placed. The group of articles is pushed into 110. At this time, the articles W at both ends of the article group slide through the surface of the holding plate 80.

  Next, the control device 30 returns the extrusion device 7, the pinching device 8, the pushing device 9, the floor opening / closing device 10, and the like to their original states. For example, the pushing plate 70 is returned to the retracted position, and the holding plate 80 is retracted and returned to the original position. Further, the pushing device 9 stops the suction function of the pushing member 91 and then raises the pushing member 91 to above the formation position of the article group. After the pushing member 91 is raised, the floor board 11 is closed.

  In parallel with these returning processes, the control device 30 lowers the pedestal 24 to place the outer box 110 containing the group of articles at the box stop position U, and then moves the rod body 23a of the restraining device 23 to the transport path. The outer box 110 is withdrawn from the box packing machine 100, and the outer box 110 is carried out of the boxing device 100 by resuming the carrying operation of the outer box carrying conveyor 22.

  Then, the same boxing operation as described above is newly repeated.

  In the present embodiment, the guide portions 80 b in the vicinity of the edge on the stopper plate 17 side of each of the pair of holding plates 80 are configured to approach each other as they approach the stopper plate 17. Therefore, for example, even if the article W is stored in a bag having a long ear portion Wa, such as a header portion of a bag with a header, the extrusion plate is pushed out from the alignment conveyor 6 so that the ear portion Wa is in contact with the stopper plate 17. When the plurality of articles W are pushed out by 70, as shown in FIG. 3, the articles W at both ends are pushed out by bending the ears Wa along the guide portions 80 b of the pair of holding plates 80. Thereby, it is possible to prevent the ear portion Wa from protruding from the gap between the holding plate 80 and the stopper plate 17, and when the plurality of articles W are pushed into the outer box 110, the ear portion Wa is a gap between the flaps of the outer box 110. And the like can be stored in the outer box 110 accurately.

  INDUSTRIAL APPLICABILITY The present invention is useful as a boxing device or the like that can accurately store even an article whose contents are stored in a bag having a long ear portion in an outer box.
