Finishing Machine / Model 120
BD Uniject ®
BD Hypak SCF  and Uniject are registered Trade Marks of Becton, Dickinson and Company, Franklin Lakes, NJ, USA 07417
Function of Machine:

The Uniject™ Finishing Machine processes reels of filled and sealed Unijects. The basic machine performs the following functions:

Inspect for the presence of liquid.
Inspect for the presence of needle shields.
Apply pressure sensitive labels, front and back.
Cut individual Unijects out of the strip.
Reject Unijects that failed inspection.
Dispense finished, accepted Unijects.

The machine will process all Uniject™ in the reel, including the first leading and last trailing one. A new reel can be fed in manually without stopping the machine, and a wheel will pick up and carry in the leading edge of the reel.

Descrition of operation

Continuous motion carries the product through inspection and labeling. Die cutting is done intermittently, producing four products per cycle at 30 cycles per minute, so that 120 Uniject™ are finished per minute. The transition from continuous to intermittent motion is handled internally within the machine, without loss of leading or trailing products. The machine was designed to use a minimum of compressed air, and the cutting press is driven by a stepper motor. The control is by a PLC, and the operator interface is a monochrome touch screen. The machine is self-diagnostic, so that if any problem occurs, such as a material jam, consecutive inspection failures, etc., a graphical message display will explain why the machine stopped to enable prompt operator attention.

An OSHA compliant safety enclosure surrounds the mechanical components, with doors interlocked so that the machine will not run when a door is open. The machine is built of non-corrosive materials, in a design amenable to a pharmaceutical production environment. The base machine will be supplied with tooling for one product size, and one unwind stand for coiled Uniject™ strips.

Optional Accessories

A number of optional accessories are available:
Printing for lot number/expiration date, by thermal transfer.
Print presence detection for lot number/expiration date.

Vision inspection for:
Particulate (subject to testing)
Label verification
Lot number/expiration date verification
Label placement/presence inspection
Position of needle shield (check for premature activation)
Special brand of PLC or control components.
Additional reel unwind stands
Die sets for additional product sizes.
Air Compressor
Automatic Pouching

Operation of Pouching Option:
Finished Uniject™ are transferred from the finishing machine or on-line particulate inspection section, shown on next page, to an infeed conveyor that carries them into the pouch, as it is formed. Two webs of pouch material come together around the Uniject™ to form pouches, which are heat sealed and cut apart. Peelable seals can be made or permanent seals with a tear notch.
The pouching section runs only when product is present so that material waste is minimized.

Optional Wrapping Accessories:
Ink jet printing for lot number/ expiration date.
Hot stamp printer for lot number/expiration date.
Thermal transfer printer to apply any copy, up to 100mm wide,including logo, barcode or instructions.
Registration control for pre-printed film, one side.
Sealing roller lift system to remove heat from the film when the machine stops.
Electronic monitoring system for temperature, web splices, empty pouches and low air supply.
Low film supply warning.
Sensor for product in pouch, with empty pouch reject.
Sensor for incoming product, with empty pouch reject.
Applicator for pressure sensitive labels to web of film including temperature monitoring stickers.
Tear-notch device.
Shingling belt conveyor at discharge.
On-Line Particulate Inspection

Operation of Inspection Option:
Finished Uniject™ are transferred from the finishing section to the inspection machine, which attaches them to a rotary carrier. As the carrier turns, the product is agitated and viewed for particulates. At another station, cosmetic inspection can be done. A reject device is included.
Two inspections systems are available. One uses operators who visually inspect images enlarged and presented on a video monitor. The other uses fully automated vision inspection.
System Integration

A finishing and packaging system can be designed to suit each customer’s needs. Elements of automated and manual operation for each function required can be integrated to create the best result for each application, optimizing investment cost and process control factors.
