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.

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. |
