Can seam forming apparatus

摘要

A double seam forming apparatus for applying end units to can bodies includes a can seamer (12) with a seaming cam (46). Seaming cam (46) includes a high dwell portion (56) which deforms responsive to force encounterred by tooling during forming of a can seam. A reinforcing pin (72) limits deformation of the high dwell portion to prevent damage. The high dwell portion of the cam includes a force sensor (20) which generates a signal responsive to strain of the high dwell portion due to applied force. The apparatus further includes a monitor apparatus (28). The monitor apparatus includes a controller (30) which includes a processor and a data store (32), and a host station (38). The monitor apparatus is operative to identify seam fault conditions and to store data concerning seamer conditions. The monitor apparatus also operates a can ejector (26) to divert cans identified as having defective seams.
