ACFS-4000T Automatic Filling Machine
Available from Credence Engineering Inc.
The ACFS-4000T is the most productive Cartridge Filling Machine on the market today. It will fill up to 3600 1.0 gr and up to 4200 .5 gr cartridges per hour. It is based around the CCell and Bold injection-molded tray concept where the cartridges are accurately positioned so the XY motion system can quickly place a needle in each cartridge and fill the cartridge using the Credence Pump, which is the most precise and fastest delivery system available.
The ACFS-4000T has full temperature control through the oil path. The Vessel, the Pump, The Flexible Line to the Needle and the Needle are all independently temperature controlled for the toughest oils.
The XY Motion is a proven design and will give long service with minimal maintenance and downtime. Instead of moving the bulky tray of carts to each position like most array fillers, The ACFS-4000T moves the needle assembly, which is a much lighter load. This keeps the motion load consistent, whereas other array fillers move the Cartridge array, which continually increases in mass as the carts are filled. Another innovation of the ACFS-4000T that affects its speed is the Needle Z motion where the needle will move down and up in 1/3 of a second total. The needle motion is ½ of the total cycle time so it must be fast if the machine cycle time will achieve a 1 second cycle time. It is designed around a fast-acting DC Gearmotor Cam Drive to insure consistent needle entry into the cartridge while clearing the cartridge quickly so the XY motion system can move the needle to the next position.
The tray of cartridges loads onto a stepper motor driven Elevator that will set the top of the cartridges at the optimum height for filling. A simple menu selection will change the cart volume from .5 gr to 1.0 gr which correlates to the height of the elevator for filling.
Another key innovation is the Patent-Pending Credence Cart-Top Alignment tray. It holds the tops of all of the cartridges in the exact location and shields the outer rim of the cart so the needle is guided into the cart automatically.
