Intelligent Semi-Automatic Case Sealing for Small, Medium, Large and Very Large Cartons
The SIAT Nastro-SB-L is a high-performance semi-automatic case sealer designed for businesses that need reliable, high-speed sealing of uniform-size cartons, with the added benefit of on-board Logic and intelligent machine control.
Available in L5, L6 and L8 configurations, the Nastro-SB-L can handle cartons ranging from smaller boxes through to very large cartons up to 800 × 800 mm, depending on configuration.
Unlike conventional semi-automatic case sealers, the Nastro-SB-L incorporates electronic control, photocells and patented variable-speed technology. SIAT states that this Logic system can increase total machine capacity by up to 70%, while providing operators with production information and machine diagnostics.
The machine can also be connected to SIAT’s OptiRun IoT platform, allowing businesses to monitor machine performance, productivity, operating time, tape consumption and other production information.
What Is the SIAT Nastro-SB-L?
The SIAT Nastro-SB-L is a semi-automatic case sealer for fixed or uniform-size cartons.
The operator manually adjusts the machine to the required carton dimensions. Cartons are then fed into the machine, where side drive belts transport them through the sealing section while adhesive tape is applied to the upper and lower flaps.
Why Is the Nastro-SB-L Different?
What distinguishes the Nastro-SB-L from a conventional semi-automatic case sealer is its integrated Logic system. The “L” in Nastro-SB-L stands for Logic. The machine uses an electronic board and photocells to detect cartons and control the sealing process, including patented variable-speed operation. SIAT designed the system to increase productivity while giving operators greater access to machine and production information.
SIAT’s patented variable-speed technology can increase total machine capacity by up to 70%, depending on operating conditions.
This makes the Nastro-SB-L particularly suitable for businesses looking to improve carton sealing productivity, machine visibility and operational efficiency without moving immediately to a fully automatic case sealing system. For businesses running significant carton volumes, this can translate into more productive use of the same machine footprint.
Production Monitoring and Machine Diagnostics
The Nastro-SB-L provides operators with instant access to machine diagnostic information through its display.
This can help operators identify problems more quickly and access useful information without immediately requiring service intervention.
- Production and diagnostic information can help businesses:
- Identify machine stoppages
- Understand production performance
- Troubleshoot operating issues
- Reduce unnecessary downtime
- Improve machine utilisation
- Make better-informed maintenance decisions
Optional IoT Connectivity with SIAT OptiRun
For businesses wanting greater visibility across their packaging operations, the Nastro-SB-L can be equipped for connectivity with SIAT OptiRun. OptiRun provides access to machine and production information through a connected platform. Depending on the configuration, businesses can monitor information including:
- Machine performance
- Productivity
- Working time
- Machine downtime
- Tape consumption
- Production data
- Alarms
- Machine status
This provides an opportunity to move from simply operating a case sealer to having greater visibility of how that machine is performing within the production environment.
Why Does This Matter?
For higher-volume operations, machine data can help answer important production questions:
- How many cartons are we sealing?
- How much time is the machine actually running?
- How often is the machine stopping?
- How much tape are we consuming?
- Where are production losses occurring?
This information can help businesses make more informed decisions about production, maintenance and future automation.
Smart Energy-Saving Operation
Energy efficiency is incorporated into the Nastro-SB-L as standard. The machine includes an energy-saving system, and the machine motors and conveyors can stop after a defined period when no carton is detected. This means the machine is not simply designed for high throughput; it is also designed to avoid unnecessary operation when cartons are not being processed.
