Abstract

Air cylinder A moves carrier B and pusher C, thus moving cartridge D through marker position E to position F where it is held in place with a retainer spring G, preventing cartridge F from moving back into the path of the next cartridge, possibly causing deformed printing. The spring also holds cartridge F directly over the reject chute H, so that it may be rejected down the chute by retracting gate J. The distance between cartridges E and F permits cartridge E to be completely marked before it hits cartridge F since such an impact could cause deformed printing. The ink jet marker K is clamped in an adjustable V-block behind and perpendicular to cartridge E. A transparent PLEXIGLAS* safety shield L covers marker station K and E to prevent damage from an accidental ink discharge.

Cartridge-Marking Mechanism

Air cylinder A moves carrier B and pusher C, thus moving cartridge D through marker position E to position F where it is held in place with a retainer spring G, preventing cartridge F from moving back into the path of the next cartridge, possibly causing deformed printing. The spring also holds cartridge F directly over the reject chute H, so that it may be rejected down the chute by retracting gate J. The distance between cartridges E and F permits cartridge E to be completely marked before it hits cartridge F since such an impact could cause deformed printing. The ink jet marker K is clamped in an adjustable V-block behind and perpendicular to cartridge E. A transparent PLEXIGLAS* safety shield L covers marker station K and E to prevent damage from an accidental ink discharge. During operation, cartridge D is moved through position E, thus actuating photocell (PC) 1. This tells the control system that there is a cartridge in the marking chamber. Photocell 2 actuates the ink jet, to start printing. Air cylinder A has an adjustable velocity control to get the required printed length. Photocell 3 indicates that the cartridge has arrived at position F. The system immediately sends pusher C back, triggering photocell 4 to await the next cartridge. * Trademark of Rohm & Haas Co.
