Pharmaceutical Packaging Line Upgrade

automated medical soap packaging linePHARMACUETICAL AND MEDICAL DEVICES PACKAGING

A healthcare company approached EPIC Systems with a need to upgrade an existing pail and drum filling line for its pharmaceutical grade products.

CLIENT: A Fortune 500 company

INDUSTRY: Medical

KEY ENGINEERING FEATURES:

    • Complete controls upgrade to an Allen Bradley PLC system
    • Integrated ABB robotic palletizer with packaging line
    • Laser displacement sensor for drum orientation
    • Job storage and intuitive project recall to develop programs for “touch-a-button” quick changeover of line settings for each container size
    • Weigh-cell technology used for filling

 

CORE CHALLENGES:

    • Pharmaceutical grade clean-in-place CIP product
    • Previous equipment efficiency and reliability issues
    • Robotic palletizer could not easily interface with packaging line
    • New equipment could not be purchased due to customer budget constraints

 

AN EPIC SOLUTION

Front-end Engineering

EPIC first completed its front-end engineering approach to assure the most efficient line solution and accurate cost quotation. After reviewing the state of the current packaging line with the client, EPIC’s engineers completed a line analysis and created an implementation plan that included the following elements:

    • Complete controls upgrade to Allan Bradley PLC system
    • Special interface for ABB robotic palletizer
    • Filler upgrade for multiple product flow through one filling machine
    • Customization of a pre-programmed line with filler settings for each container size
    • Line validation

 

EPIC Systems recommended an efficient option for advanced line automation and machine vision inspection for QA checks.

EPIC’s Proven Solution

EPIC completed several packaging line modifications, removed the custom control system and upgraded to an Allen Bradley PLC. A special interface was developed to allow the ABB robotic palletizer to communicate with the packaging line. This also allowed for easier troubleshooting of the robot by line operators.

The line operator selects a program from the operator interface with pre-installed correct line settings for each container size. Manual part switch over was reduced for quick changeover during container sizes change.

A robotic palletizer/de-palletizer lifts empty containers from pallets and places them on the line for filling. Containers are oriented for filling by a rotary alignment tool and a laser displacement sensor. The laser displacement sensor locates the opening in each container by bouncing a laser beam off the surface of the container. When the laser passes over the hole, the sensor does not receive a bounce back and signals the location of the opening to the alignment tool.

Oriented containers move through the line to the filler. The operator selects a pre-set program from the interface, to change the filler settings, dependant on the type of product being filled. EPIC’s programmers automation of the packaging line allow settings for filling parameters, based on product properties such as density, composition and tendency towards foaming. In the previous process, multiple products could not be run on one filler.

To fill the containers a lance is lowered to the bottom of each container. The filler releases fluid into the container, keeping the lance below the liquid level to prevent foaming. A weigh cell rises to weigh the drum and determine when full. A cap is manually tightened and the container travels back to the same robotic palletizer, staking the containers on a pallet for shipping.

After EPIC completed the controls upgrade, the line was validated and checked for compliance.

IMPACT:

    • Product has increased consistency in fill weight
    • Reduce costs through packaging line controls upgrade, increasing line efficiency and reliability and utilizing pre-existing equipment
    • Significantly reduced downtime
    • Created more efficient interface between robotic palletizer and packaging line, allowing for easier troubleshooting
