Sitma launches Symphony sorting system

Sitma Machinery is launching Symphony, a sorting system with cutting-edge technology that takes up the baton of its Easy Sort and Speedy Sort predecessors.

According to the Italian manufacturer, Symphony can be configured in both a "tilt tray" and "cross belt" mode responding to changing customer needs for faster throughput.

The first example of this technological evolution was created for an important operator in North America, where it is currently being installed, with testing expected by autumn of this year.

Multiple configurations

Sitma said it has put in place “the know-how accumulated in over 40 years of activity in the logistics sector” to launch a system that is able to support particularly complex configurations.

Symphony can in fact be set up with straight or curved modules, suitable for supporting upward or downward movements and preserving the packs from the risk of falling and damage — even at high speeds. “All of this is achieved in incredible silence,” it noted.

A single modular base structure allows the use of both a tilt tray and cross belt technology, depending on the specific needs. Symphony can also support multi-output and multi-directional configurations, helping to increase production capacity and line efficiency.

The chutes for unloading products allow for maximum flexibility, giving customers the opportunity to manage different outlet configurations and container positions for collecting the products. Even for large dimensions, the outputs can be dynamically configured according to the changing production needs.

Top speed and capacity performance

Symphony is also a fast worker, being able to manage up to 14,000 products per hour in the tilt-tray configuration and up to 20,000 with cross-belt configuration. The system also boasts an increased load capacity compared to previous solutions, being able to sort larger and heavier products. In the tilt-tray configuration it reaches up to 15 kg per tray, while in the cross-belt configuration, it can manage up to 30 kg.

These performances require a handling system that guarantees operational fluidity and maximum reliability, Sitma pointed out. Symphony runs on polyurethane wheels, specifically designed to minimize noise (which is below 70 decibels) providing add-on value in the work environment.

The system is also gearless and equipped with standardized transport cells, which are very light and highly technological. The brushless motors are installed on-board and each cell is powered by electricity; being interconnected via Wi-Fi with the PLC, to communicate its positioning in real time.

These features are not only useful for purposes of planning sorting activity (for example to send and receive inputs from PLC for unloading) but also for the constant monitoring of the line. To be more precise, it’s possible to know where the products are at any given moment in time.

Finally, Symphony minimizes maintenance activities by using a high number of identical parts. Sitma has also turned its design efforts towards a solution that is completely "Maintenance Free:" a goal that can be achieved by equipping the sorter as an alternative to mechanical traction systems, with electromagnetic traction solutions. In this case, linear motors and magnets are used, which are installed directly on the cells. In addition to the total elimination of maintenance activities, this also entails a further reduction in noise.
