The axial direction of the second inserting rod 134 is perpendicular to the length direction of the second connecting rod 132. After the second inserting rod 134 is inserted into the insertion hole 161 of the tray 16, the second transfer cylinder 131 moves the second connecting rod 132 and the second inserting rod cylinder 133 to transfer the tray 16 from the second conveying section 12 to the third conveying section 13. When it is needed to transfer the packaging bottle 9 from the second conveying section 12 to the third conveying section 13, that is, to transfer the packaging bottle 9 from the transfer warehouse 21 to the working warehouse 22, first, the second transfer cylinder 131 drives the second connecting rod 132 to move the second connecting rod 132 to the second conveying section 12 until the second inserting rod 134 is aligned with the insertion hole 161 of the tray 16. Then, the second inserting rod cylinder 133 drives the second inserting rod 134 to insert the second inserting rod 134 into the insertion hole 161 of the tray 16. Then, the second transfer cylinder 131 drives the second connecting rod 132 to move the second connecting rod 132 to the third conveying section 13.
