Introduction to the Vormek Converix VLM-500
Increasing production capacity consistently brings new challenges in product transfer. Many automatic tray sealers, designed to achieve higher throughput, package and discharge products in two or more parallel lanes. While this method improves packaging efficiency, downstream equipment—such as automatic labelers, jet printers, quality control systems, checkweighers, cartoners, and palletizing robots—typically require single-file product input with uniform spacing.
Consequently, many factories still rely on manual labor to convert multi-lane output into a single lane. This creates bottlenecks, increases costs, and introduces contamination risks.
At the same time, physical space constraints in many facilities make straight-line (in-line) expansion impossible. In such cases, technology that can simultaneously perform lane merging and directional changes is essential.
The Converix VLM-500 is an advanced engineering solution developed to address both challenges simultaneously. This system can convert multi-lane packaging machine output into a single-file flow while simultaneously redirecting product movement by 90 degrees. The result: reduced floor space requirements, elimination of manual operations, increased productivity, and a foundation for complete packaging line automation.
The Industry Challenge – The Hidden Cost of Manual Product Merging
In many food production lines, transferring output from packaging machines to downstream equipment is still performed semi-manually. Operators collect products from multiple lanes and place them onto the next conveyor in single-file order. While this may seem simple, at industrial scale it creates far-reaching consequences:
| Consequence | Description |
|---|---|
| Increased labor costs | Multiple operators required per shift |
| Line dependency on operator | Performance tied to operator availability and skill |
| Fatigue and quality decline | Performance drops during late shift hours |
| Bottlenecks during peak production | Slows overall line output |
| Unplanned stoppages | Disruptions from manual handling errors |
| Reduced downstream equipment efficiency | Inconsistent feed affects labelers, printers, and checkweighers |
| Increased contamination risk | Hand contact with products and containers |
Studies in packaging lines show that a significant portion of short-duration line stoppages are caused by product transfer and sorting issues.

Space Utilization – The New Manufacturing Constraint
One of the most significant limitations in today’s factories is available floor space. Rising expansion costs mean many production facilities cannot extend their packaging lines in straight configurations. Designers are increasingly turning to L-shaped, U-shaped, and multi-path layouts. However, changing product flow direction without disrupting output order requires specialized equipment.
The Engineering Solution – The Pop‑Up Concept
The Converix technology is built on a simple yet highly effective engineering principle: controlled product flow redirection combined with multi-lane convergence into a single path.
Unlike conventional mergers that only perform lane consolidation, the VLM-500 simultaneously:
- Receives multi-lane output
- Accommodates various container heights
- Redirects flow by 90 degrees
- Delivers single-file output
- Synchronizes speed with downstream equipment
System Architecture
Primary Roller Transfer Module
The first section is positioned along the tray sealer’s discharge. It features transfer rollers that receive products from the machine. The Pop-Up mechanism lowers the product by approximately 4–5 cm, enabling smooth, controlled transfer to the new path.
Polycord Conveyor Module
The second section features a conveyor equipped with Polycord belts. This technology offers multiple advantages:
| Advantage | Description |
|---|---|
| Controlled friction | Smooth, non-slip movement |
| Gentle product transfer | Suitable for sensitive or lightweight containers |
| Minimal wear | Long Polyurethane belt life |
| High washability | Resistant to water and detergents |
| Debris drainage | Contaminants pass between belts rather than accumulating |
Adjustable guide rails ensure precise product guidance.
