Case Study

Metering for a Leading Supplier of Vision Inspection Solutions

Operating Speed: 150 CPM

Container: 30 oz

Customer Container Handling Challenge 

A leading supplier of vision inspection solutions required a reliable way to space 30-ounce round PET containers prior to entering an inspection system on an existing high-speed production line. The containers—empty, uncapped, and warm—needed to be accurately metered at a throughput of 150 containers per minute. Tight line spacing and a 90-degree turn just before the inspection area presented additional challenges for maintaining consistent product flow and orientation.

Morrison Solution 

Morrison provided two custom-engineered Metering Drive Systems—one configured for left-hand (LH) operation and one for right-hand (RH) operation. These systems were developed to accommodate the unique needs of the customer’s line, with careful consideration given to spacing requirements, line geometry, and the physical properties of the containers.

Each system included an inline AC gearmotor and a mechanical overload clutch to drive a precision-engineered timing screw designed to provide 1.5× container spacing. Electrical control systems were delivered in NEMA 12-rated enclosures, built to Morrison’s standard specification and equipped with PLCs, HMIs, VFDs, and Ethernet communication capabilities. The design also included integrated photo eyes and E-stop functionality to support safe and efficient operation.

Construction 

Built from anodized aluminum, each Metering Drive System was designed for long-term durability and compatibility with the customer’s existing conveyor setup. Key construction features included:

Mechanical overload clutch and inline gearmotor drive

Stainless steel weldment stand for HMI and control enclosure

Lift-off guarding with a top cover configuration for ease of access

Full mounting hardware and support legs tailored to the line’s footprint

36” long, 5” OD timing screw for smooth, controlled container handling

Controls were configured for 480/230V operation and aligned with the customer’s plant standards, with some flexibility in component brands as needed.

Results

Morrison’s solution offered dependable metering and spacing of warm PET containers at full line speed, supporting optimal performance of the downstream inspection system. The customized timing screw geometry and system layout addressed the spatial constraints and provided the precise discharge spacing necessary for inspection readiness.

The combination of mechanical reliability and user-friendly controls enabled smooth integration into the customer’s existing line. Morrison also supported the installation with robust documentation, including 3D assembly drawings, bills of materials, and detailed operations manuals, helping ensure a confident transition into production.
