| Double die flanging and automatic bottom and rings seamer
GENERAL CHARACTERISTICS
This transfer unit is used for the production of round cans. Consisting of two horizontal seamers, STAV175 and S121, it is able to create a can with bottom and ring in a small space. The can bodies, fed by a drop chute, are flanged with dies; then, the bottom seaming is carried out and passing through an integrated transport system, the cans are brought to the S121 module which, through another star conveyor, arrives at the second seaming station to apply the ring or dome. The operator’s intervention is limited to feeding the curled bottoms and rings/domes into the special magazine equipped with a blade picker, since the can bodies are automatically transported from one workstation to another by means of star conveyors and integrated transport between machines. Other special versions of this machine are available on request.
FUNCTIONING
The can bodies, placed in the inlet chute, pass to the star conveyors which transport them to the various stations. In the first, the flanging takes place at the ends simultaneously by means of two dies.
This system allows an exact calibration of the bodies, which is particularly recommended for the subsequent seaming of the bottoms and lids. At the seaming station the flanged bodies are transported by the star conveyors together with the bottoms mechanically fed by the blade picker. The seaming takes place when the can is stationary by means of a four-roller seaming head (two for the first and two for the second operation), which guarantees an absolutely safe closure. The seamed bottom cans are ejected by a special lever and cam on the integrated conveyor transport to lead them to the S121 module.
The movement of the cans and the feeding of the bottoms and rings are controlled by non-contact sensors, which control the stop of the machine in case of need. This occurs when there are no bodies, bottoms or when the conveying stars are subjected to excessive strain due to jamming (this also applies to the S121).
All the cams, the gears as well as the eight-position intermittent mechanism rotate in an oil bath. All fast-moving parts are mounted on ball bearings or needle roller bearings.
TOOLING CHANGE
The replacements necessary in the event of a change in diameter can be carried out in a maximum of about two hours of work. For the change of can height only, a few adjustments are necessary which take only a few minutes.
