Progressive Die Manufacturing One Piece Cans with 1394 Motion Control
In high speed manufacturing of beverage cans, speeds over 100 cans per minute are expected as throughput. Servo systems are uniquely capable of handling machine processes at this speed and accuracy.
One-piece can manufacturing is a three-step process. In the first step, aluminum is unwound from the roll and accurately measured. One axis of the 1394 servo system is used to unwind the material to keep pace with the high speeds of the punching operation. A second axis is used to precisely measure and feed the material into the stamping process. The second step of this process is a coarse cutting and forming operation performed by the initial stroke of the stamping head. A quick belt-driven shuttle driven by a third axis accurately moves the cans between the second and third step which is the final forming and finishing operation of the can, performed by the second stroke of the stamping head.
A programmable limit switch (PLS), or output cam, is utilized to coordinate the shuttle motion in relationship to the stamping mechanism ensuring high speed and accurate movement of materials synchronized to the stamping process.
