Pharmaworks introduces TF1pro blister machine

Published: 29-Oct-2020

Suitable for pharmaceutical and biotech manufacturers and contract packers that frequently changeover, the servo-driven blister machine runs up to 100 indexes (200 blisters) per minute

Pharmaworks has introduced the TF1pro, the most advanced system in its TF1 family of compact blister machines.

The TF1pro has cGMP features for product safety and cleaning, while also achieving “fast changeovers, superior accuracy and extreme versatility,” the company says.

Suitable for tablets, capsules, softgels, vials, syringes, liquids and more, the intermittent-motion TF1pro supports both thermoforming and cold forming applications and is compatible with all corresponding materials including polypropylene. The usable forming area is 120 by 165 mm with a depth of 25 mm. Optional product vision inspection and print vision inspection are available, as well as full serialization if needed.

The TF1pro includes cGMP features. Sloped surfaces throughout eliminate the chance of cross-contamination from trapped product. The reject / transfer station uses a vacuum arm to lift the ‘good’ blisters onto the outfeed conveyor while ‘bad’ blisters drop down into the reject bin. The overload detection capability automatically stops the seal station if out-of-tolerance pressure is detected. Base material is handled via a specialised dolly designed to enhances sanitation, speed changeover and improve operator ergonomics. On the machine, the base material is enclosed to protect it from particulate matter.

Designed for manufacturers and contract packers running medium and small batch sizes such as clinical trials, the TF1pro changes over in less than 10 minutes with no tools required. It features slide in and lock components, including the guide track on the feeding station. Quick release covers on each station improve access. The heat area automatically retracts when not in use for operator safety and convenience during changeovers and maintenance. A colour touchscreen HMI, up to 50 cm in size, shows the user interface.

By using sensors instead of pendulum rollers to handle the web, material drag and necking is eliminated. A die cut laser registration system aligns the index so the materials are correctly placed and cut every time, Pharmaworks claims. Contact heating is available at the preheat station to improve heat transfer for improved efficiency, less wear and lower energy costs. The dynamic seal pressure adjustment feature allows the TF1pro to change the amount of seal pressure without stopping the line.

The modular device accommodates different feeders, accessories and floor plans. When feeding is done manually, operators can work from either side of the machine. The frame accommodates a containment system at the feed area, when needed. Multiple outfeed options allow blisters to be transferred out the front, the rear or the side of the machine. All stations are independently driven and can be turned on and off separately.

The TF1pro is available with various options. Selective forming enables specific pockets to be turned on and off within the same tool. Low level detection alerts operators before a new base or lidding roll is needed. Pinhole detection for the lid material and/or the base material is available for cold forming. Additional options include a lid material splice table, a splitter, servo plug assisted cold forming and both helium and nitrogen gas flushing.

An Allen-Bradley PLC controls machine functions and the HMI is PC-based to maximize operator ease of use.
