By releasing the holding of the holding device (4), the upper can body (lla) is guided by the guiding member αη of the holding device (4) and moves to the second holding position without contacting the lower can body (11bJ). The portion (7) allows the cans to be smoothly fed out sequentially and in tandem following the lower can body (11bJ).

Furthermore, it is not necessary to cut the can body head in a horizontal position as in the conventional method, divide each divided can body aη into two directions, and then merge them again to arrange the can bodies Qη in a column K. Because of this, each cut can body (11) can be moved at a high speed without causing any damage.
(b) can be efficiently sent.

(Effects of the Invention) According to the present invention, the method for manufacturing a separate can body of the first invention moves a can body having a plurality of can body lengths in an upright state, and moves this moving can body in an upright state. The can bodies are cut, divided, and stacked to form each can body, and when the divided and stacked can bodies are moved, only the upper can body is held upward, the lower can body is advanced, and the lower can body is moved. When the can body moves, the upper can body is released and moved, so it is easy to cut and divide one can body, and it is possible to easily cut and divide each can body without damaging the can bodies that have been formed separately. It has the effect of being able to send out messages in a certain state.

Further, the splitting device for separate can bodies of the second invention has a turret that rotates horizontally, and a peripheral edge of the turret with a gap in the circumferential direction of the button, passing through the button in its axial direction, and having one peripheral edge open. A space communicating between the first and second holding parts that hold the can body in an upright state and the first holding part, which is formed by cutting out a part of the upper peripheral edge of the turret, and the turret. a cutting device including a cutter that can be freely inserted into the can body moved by the first holding part and cuts the can body in the circumferential direction thereof; and a cutter guide provided at an outer position along the circumferential direction of the turret. and a holding device for holding the cut can body above the position where the first holding portion of the turret passes.

Therefore, since the first holding part is provided at the peripheral edge of the horizontally rotating turret, the can body can be moved in an upright state with this first holding part, and can be cut to form divided can bodies in a stacked state. I can do it. In addition, a first holding part, a second holding part, and a space are provided between the two holding parts at the peripheral edge of the turret, and a holding device is provided above the position where the first holding part passes, so that the turret is divided into two parts and stacked. Since the upper can body of each can body can be held upward by the holding device and retracted in the space, the lower can body can be quickly transported first.

If the upper can body is released from its hold, it can be moved by the second holding part, so the separate can bodies can be fed out smoothly and efficiently in tandem without damaging the cut and divided can bodies. It is effective in providing mounting equipment.
