Available envelope
Measure conveyor width, height, services, guarding and maintenance access.
Existing-line vision projects
Retrofit label inspection to an existing production line
Add label presence, position, identity, print and code checks without replacing the complete packaging line—where space, handling and controls allow a reliable solution.
✓ Site and line survey✓ PLC and reject interfaces✓ Planned installation window
Can label inspection be added to an existing line?
Usually, yes. A retrofit can use the existing conveyor when product presentation, space, structure and controls are suitable, or add a dedicated inspection conveyor when spacing, orientation or rejection needs more control. A survey confirms the inspection point, camera views, lighting enclosure, tracking distance, reject route, guarding and electrical interfaces before the design is fixed.
Retrofit survey
Check the complete production function, not only camera space
The smallest visible feature may set camera resolution, but handling and reject distance often determine whether a retrofit can work reliably.
Product presentation
Observe pitch, orientation, vibration, rotation, stops and changeovers.
Controls
Define triggers, encoder tracking, PLC signals, recipes and fault behaviour.
Failed product
Provide enough distance and containment for reliable rejection or line stop.
Mechanical and controls scope
A compact retrofit still needs controlled presentation
Camera brackets alone are rarely the complete answer. The station may require guides, side belts, spacing control, an enclosure or a dedicated conveyor section.
- Camera, lens, lighting and protective enclosure
- Product guides, spacing, orientation or controlled rotation
- Encoder-based tracking from inspection to rejection
- PLC handshakes, interlocks and recipe selection
- Reject confirmation, bin monitoring and fail-safe responses
- Operator access, cleaning and maintenance clearances
Installation planning
Reduce production disruption with agreed boundaries
Survey data, off-line build and factory testing allow site work to focus on planned mechanical, electrical and software interfaces.
- 01
Survey
Record products, faults, speed, space, interfaces and the existing risk assessment.
- 02
Prove
Trial representative samples and confirm the camera and lighting concept.
- 03
Build
Prepare the station, interfaces, recipes and challenge tests before site work.
- 04
Install
Complete the planned shutdown, commission, train and test the reject sequence.
Practical answers
Retrofit label inspection questions
Do I need a new conveyor for a retrofit?
Not always. The existing conveyor may be suitable when it presents products consistently and provides enough space for lighting, tracking and rejection. A dedicated section is recommended when greater control is needed.
Can the vision system connect to an existing PLC?
Yes, where the signal list, protocol, ownership of recipes and behaviour during faults or communications loss are defined with the line integrator.
How much line space is required?
It depends on camera working distance, enclosure, product spacing, orientation and reject distance. A site survey provides the dimensions needed for a real layout.
Can installation be completed during a planned shutdown?
Projects can be designed around a shutdown window, but the duration depends on mechanical changes, wiring, controls interfaces, guarding, testing and production handover.
