CASE STUDY – Flip top caps closing system
Written by: Ying Zhang
Plastic closures incorporating a flip top cap are in high demand in pharmaceutical, processing and packaging industries. The need for quality and cost are driving plastics injection moulding companies to search for improved cap closing solutions.
RNA were contracted to design and manufacture an automated cap closing system for a range of flip top caps. It was developed for flip top caps that are open after going through the injection moulding process, the caps must be closed prior to being used by manufacturers or packaging companies.
The RNA cap closing system incorporates a bowl feeder, a closing system and PLC control system. The project was for a plastic injection moulding company that manufactured a diverse wide range of bottles and closures.
a. Ø24mm x 26mm tall; b. Ø28mm x 24mm tall; c. Ø28mm x 30mm tall
RNA designed and developed an in-line cap closing system complete with vibratory bowl feeder and PLC control. The bowl feeder feeds and orientates components all one way via a conveyor to the closing system. The end of the conveyor is fitted with a counter and stop cylinder.
The closing system operates in 2 stages: pre-close and final close. It is envisaged that the mechanism closes 10 caps at a time – more efficient and reliable than a conventional system does. Closed caps are discharged from the end of the conveyor for collection by the customer’s equipment. The closing system checks for unclosed caps, and these are discharged via a reject chute.
Changeover between components is accommodated via interchangeable tooling to fixed positions within the bowl, and with quick release fasteners on the conveyor and cap closer.
