In this state, the engagement between the small diameter portion of the cam 71 and the cam follower 72a is released, the cam follower 72a starts to engage with the large diameter portion of the cam 71 again, and the levers 66 and 67 are shown by a chain line in FIG. The gripping pieces 69 are rotated counterclockwise from the position and are moved upward while gripping the empty bobbin E, and the empty bobbin E is pulled out from above the peg 17.

The gripping piece 69 gripping the empty bobbin E is rotated outward when the gripping piece 69 moves to the raised position shown by the solid line in FIG. In this state, since the top of the empty bobbin E is engaged with the belt conveyor 76 and the guide member 79 of the empty bobbin transfer device 24, when the gripping by both gripping pieces 69 is released, the empty bobbin E is guided by the guide member 79. While being vertically held by the carrier belt 77 and held by the carrier belt 77, the carrier belt 77 is transferred upward and is fed to the empty bobbin inserting device 23.

The empty bobbin E sent to the empty bobbin inserting device 23 in the vertical state collides with the lower surface of the receiving plate 81a of the empty bobbin receiving member 81 in a state where the engagement between the belt conveyor 76 and the guide member 79 is released. . Then, due to this collision, the empty bobbin receiving member 81
Is rotated counterclockwise in FIG. 3, and the empty bobbin E is pushed out to the right in FIG. Next, the empty bobbin E is carried to the front side of the pipe changer 1 while being held by the guide plate 82 and the belt 83, and is sent to the empty bobbin shooter 85. As shown in FIG. The lower ends of the 85b are supported by the receiving pieces 85b, and are held in the empty bobbin shooter 85.
