The NERI SL 400V automatic labeling machine is fed with cartons via a conveyor belt or feeding device. The system detects the presence of the product using photocells, applies the label with the stepper motor, and verifies correct application. In the event of an error, the system automatically rejects the product.
All adjustments—roll changes, printing ribbon, and formats—are accessible from the control panel for easy operator intervention. Operations are performed safely, thanks to CE-certified devices.
To calculate the optimal speed:
Case length \text{Line speed} = \frac{\text{Number of products/hour}}{3600} \times \text{Cases length}
For example, if you want to label 7200 pieces/hour and the carton is 60 mm long:
frac{7200}{3600} \times 60 = 120 \text{ mm/s}
Thermal or thermal transfer printers
Power and transport devices
Vision systems for quality control
Upper labelling machines for secondary labels
The machine is equipped with devices compliant with CE regulations , but for used machines, an inspection by a qualified technician is still recommended. If certification is not available, it can be adapted by:
Physical protections on moving parts
Visual and acoustic signals
Electrical system check according to Machinery Directive 2006/42/EC
Proper maintenance significantly extends the useful life:
Daily cleaning with antistatic cloths
Weekly check of roller wear
Monthly lubrication of mechanical components
Periodic check of photocells and rewinding system
No corrosion on the steel structure
Perfectly readable and operational display
Wiring intact and untampered with
Smooth movements without abnormal noises
Presence of original manuals and electrical diagrams
Buying a used NERI SL 400V is a smart investment for those looking for a robust, precise, and easily integrated machine at a reasonable cost. It's ideal for small and medium-sized businesses looking to automate their labeling without sacrificing quality.
