Americas: Fowler Products offers gently, high speed inspection/rejection capping solution

Fowler Products, powered by Pro Mach, Inc., has launched its highest speed inspection/rejection system for capping applications.

The system can cap and inspect more than 900 bottles per minute, which is designed for pharmaceutical, personal care and food companies.

In Fowler’s approach to inspection/rejection, bottles failing inspection are shunted off to a reject lane before they leave the capping machine.

The rejected bottle is gently directed off to a reject lane so that it remains upright and does not spill its contents contaminating the packaging line.

“Because the system is integral to the capping machine, we can absolutely assure customers that the proper bottle has been rejected,” says John Artman, VP of sales.

“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.”

The system rejects bottles for improper torque, and missing, high and cocked caps.

It also rejects bottles if the under-cap liners are missing.

Each bottle must pass these quality checks before it is allowed to leave the machine.

The system uses electronic torque control, machine vision, and other sensor technologies.

With failsafe logic, even the sensor hardware is monitored for proper functionality.

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.

Speed is realized using linear motors for high velocity, precise motion actuation of the multi-finger rejection portion of the system.

The linear motor actuators smoothly guide the bottle to the rejection lane without holding up or otherwise interfering with the bottle next in line.

“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,” says Artman.
