A protective cap fitted to the cavity is installed to be transported under the punching head of the punching cylinder 52a located at the bottom of the fixed block.

Hereinafter, a can capping process according to the present invention will be described.

At first, when the can 10 is deposited on the transfer roller plate 26 through the entry shelf 26b, the transfer cylinder is operated to transfer the can to the front of the conveyor belt 21. Then, the push cylinder is operated by the entry cylinder. The can rises above the conveyor belt 21 by 26c. Therefore, the can is transported on the conveyor belt 21, and the lifter 22 is lifted by the central control system which detects it when passing through the first lifter 22, thereby removing the can from the conveyor belt 21. After the lifter 22 is fully lifted up, the transfer stops, and the gripper 22c, 22d positioned in the diagonal direction of the can is operated by each operation cylinder to hold and position the can positioned higher. Hold firmly so that there is no flow. Then, the punching cylinder 32 is operated to be transported and gripped between the elastic pieces 33a and 33a, and the inner cap 11a is pushed downward to be inserted into the outlet of the can.

The lifter 22 is lowered again so that the can 10 is carried on the conveyor belt 21 again to the next process. Similarly, when approaching the next lifter 23, the can 10 is positioned by the grippers 23c and 23d in proximity to the bottom of the seaming head 43 in the same operation sequence as described above. And the seaming head 43 is lowered while rotating, thereby seaming the spout end portion fitted with the inner cap. The lifter 23 is lowered again so that the can 10 is transported toward the last lifter 24, and then, the lifter 23 is lifted up close to the punching cylinder and is fixed to the position by the clamping block 53 and the transport cylinder 52c. The protective cap 11b located above the can ejection outlet 11 is forcibly crimped to the ejection outlet end of the can by the punching cylinder 52a. Finally, the can is conveyed to the next with the lifter loaded on the conveyor belt 21 again.

Since the cans are continuously transported on the conveyor belt 21 in the capping operation of the can in this order, the inner cap insertion process, the seaming process, and the protective cap mounting process may be simultaneously performed.

As described above, the present invention is configured to automatically carry out the capping operation of the can, and thus, unlike the conventional manual work, it is possible to expect a very high productivity. Can be lowered.
