Recently Jornen supplied a well-known pharmaceutical manufacturer a Blister Packaging Line with cutting-edge features.
Adopt a vibratory-drum feeder. This rolling drum structure is typically used in continuous-motion Blister Packaging Machines, but its design in this line also makes it ideal for intermittent Blister Packaging Machines.
In continuous-motion Blister Packaging Machines, the rolling drum rotation is synchronized with the web index of the machine in a continuous motion, and the product remains in the drum pocket until it is released into the blister pocket. However, in an intermittent Blister Packaging Machine, the web index moves intermittently, and the speed of the index may be too fast for the feeding plate to guide the tablets to the rolling drum, causing the pills to dump out of the pockets or get damaged. The drum’s motion and structure were innovatively designed to address this issue. The drum’s system was modified to have pockets divided into several groups distributed at an angle around the circumference of the roller. Moreover, the roller has two different speeds, enabling the feeding plate to smoothly guide the capsules or tablets to the drum. The feeding system runs in cycles like this.
To ensure quality assurance, the blister line has a camera inspection system before the sealing station to inspect defects such as wrong color or size, broken or chipped tablets, and empty pockets in the blister packaging. Additionally, the blister line can equip a camera inspection system after punching to detect defects such as sealing wrinkles, unclear sealing grid linear (rotary sealing Blister Machine) or unclear sealing dot (platen sealing Blister Machine), crushed or damaged tablets in the pocket caused by incorrect sealing position, human hair or other objects sealed between lidding and forming material, unclear embossed letters and numbers, and no embossing or wrong embossing position.
For further quality assurance, the blister line has an X-ray inspection system that detects contaminants such as metal, glass, and plastics and checks for anomalies such as inaccurate feeding, missing or broken components, and incomplete items.
The connection unit is equipped with a delta robot that picks up blister cards and transfers them to the cartoning machine synchronously for one or more blister cards in one carton (according to customer requirements). These servo control systems ensure stable and flexible operation of blister transfer from one unit to another.
