As a result, the suction action on the article 12 from the suction chamber 29 is released, and the articles 12 and 12 adsorbed and held on the surface side of the suction plate 33 (which is directed toward the packaging box 14) fall, and the packaging is performed. It is packed in the box 14. After the slide body 43 descends to the operating position, it immediately returns to the standby position to guide the roller 37 through the notch 39b.
Then, the opening 29a is closed by the suction plate 33.

As described above, every time the carrier 24 is rotated by 90 °, the suction release device 40 releases the suction of the articles 12 and 12 of the article holding unit 28 that has reached the article packing position, and the required number of articles 12 is reached. When the packaging box 14 is packed with the packaging box 14, the packaging box 14 that has been packaged is discharged toward the next process in response to the packaging completion signal from the control device, and the next packaging box 14 is supplied to the packaging position to continue the packaging process. Done.

[0037]

As described above, according to the box packing apparatus of the present invention, articles are sucked and held in a plurality of suction chambers provided in the rotating carrier, and when each suction chamber reaches the article packing position. By releasing the adsorption and holding of the articles, the articles are sequentially packed in the waiting packaging box. Therefore, there is an advantage that the high speed operation is possible and the processing capacity is remarkably improved. Further, since the article can be received above the center of rotation of the rotating carrier and the article can be packed in the packaging box waiting below the center of rotation, the apparatus can be downsized. Further, when packing articles into a packaging box, the suction device holding the articles by suction is forcibly moved by the releasing device to cancel the suction action of the suction chamber, so the articles fall from the suction plate. It has the effect of achieving reliable boxing.
