Can Filling and Seaming Machine Interface Matrix: Connections and Responsibilities

Author: Mengdi · Technical reviewer: Hanyong · Content updated: 23 September 2026

A can filling and seaming machine interface matrix should identify where each connection ends, the conditions it must meet, who supplies and installs each side, and how both parties will verify it. Use one controlled record for each physical connection or exchanged signal. This turns a broad requirement such as “connect to the existing conveyor” into a checkable project agreement.

The matrix below is a planning template. Connection dimensions, utility limits and control responses come from the approved configuration and project drawings. It does not specify universal pressures, flows or electrical ratings.

Start with the boundary, not a list of utilities

Mark the machine, existing equipment and third-party equipment on the same layout revision. Give each transfer point, pipe connection and control interface an ID. Identify the direction of can flow, product flow or information flow. A connection can cross several supply scopes even when the machines stand next to each other.

For every ID, name the party supplying each end, the party installing the connection and the party responsible for the joint test. “By buyer” or “by supplier” alone is too broad when a pipe, valve, cable, conveyor section or software change is supplied separately.

A practical interface matrix

Use the rows that apply to the selected configuration. Expand a row into separate IDs when its connections, owners or operating conditions differ. On a phone, scroll the table horizontally.

Write utility conditions at the agreed connection point

For a utility entry, record its unit, measurement location, operating state and acceptance source. Distinguish a supply figure stated for the plant from a condition verified at the machine connection. State whether a flow value describes average demand or a peak duty and, for gases, the reference conditions used for the volume.

Utility monitoring can involve flow, temperature and pressure, as described in Endress+Hauser’s utility instrumentation overview. Select the measurements for the actual duty. This does not establish the required utility values for a particular Weichi model.

Agree signal meaning as well as the connection

A matching cable or network connection does not define what “ready,” “run,” “stop” or “fault” means to the adjoining machine. Record the signal sender, receiver, meaning, applicable mode and expected response. Include the agreed handling of unavailable upstream supply, blocked downstream flow and communication loss. Detailed response logic belongs in the approved controls document.

The OPC Foundation’s PackML overview explains standardized machine modes, states and tags for integration. Use an agreed interface standard where the project supports it; a PLC brand alone does not establish PackML or OPC UA capability. Safety-related functions require their own approved design and validation and must not be assumed to follow from ordinary production signals.

Keep options separate from standard scope

Weichi’s premium still beverage filler-seamer product page lists filling-valve CIP and seamer steam injection under optional upgrades and describes compatibility with third-party liquid nitrogen dosing. These entries identify subjects for an application review. The order specification must establish which systems are installed and who supplies their connections and controls.

Close each interface with a traceable record

Before fabrication, confirm the layout and interface revisions. Before installation, check that the supplied ends and site provisions match them. During testing, record the actual conditions, participants, result and any deviation. If a connection or control response changes, update the affected drawing, matrix row and test record together.

A factory test may use a temporary supply or simulated neighboring machine. Record that limitation and carry the actual site connection into the SAT plan. Use the FAT and SAT checklist to define the wider acceptance scope.

Questions to settle before ordering

Does a filler-seamer monoblock include the external conveyors?

The term describes an integrated machine arrangement. The quotation and scope drawing must identify external conveyors, transfer parts, controls and installation work that are included.

Can a utility list replace the matrix?

A utility list is useful input. The matrix adds exact connection boundaries, owners, operating conditions and the evidence required to close each interface.

What should be sent for an interface review?

Send the proposed machine configuration, can and product information, current layout, neighboring equipment details and available site utilities. Mark existing equipment and third-party supply. Use the quotation information checklist for the broader application inputs, then contact Weichi to confirm the equipment and connection scope.

For rate matching and buffer calculations, see line capacity planning. This interface guide focuses on connection and responsibility records.
