Capping machinery specialist Fowler Products has introduced a new inspection/rejection system for capping applications.
The new system, which is primarily targeted at pharmaceutical, personal care and food companies, seeks verification that every cap is properly applied.
With a capacity to cap and inspect more than 900 bottles per minute, Fowler's new failsafe system rejects bottles for improper torque, missing cap, high cap and/or cocked cap.
The linear motor actuators used in the system guide the rejected bottle to the rejection lane without holding up or otherwise interfering with the bottle next in line.
Fowler Products sales vice-president John Artman said: "The bottle identified as failing one or more quality conditions remains in positive control all the way from its station within the machine to the reject lane.
"This incorporation of linear motors in place of previously used pneumatic cylinders has allowed us to reach a new level of performance in speed and accuracy."
The system employs electronic torque control, machine vision and various other sensor technologies.
Fowler claims that by using failsafe logic, all bottles are tagged as "faulty" entering the machine and each inspection criteria must be satisfied as "good" before the system will allow a bottle to be discharged from the machine to the next downstream operation.
The system's high speed is due to advanced linear motors used for high velocity and precise motion actuation of the multi-finger rejection portion of the system.
