The BG Sorter CB (cross belt) offers a reliable solution for sorting a wide variety of items such as parcels or bagged goods. With the so-called full cross belt design, the cross belt conveyors are designed in such a way that a maximum belt width is achieved. The advantage for customers: More usable belt area is available for the same sorter size. This means that a wide variety of goods can be handled easily and safely. The risk of products remaining between the belts is reduced. The E-tray design (tilting tray) also offers advantages. An improved tilting tray design prevents the conveyed goods from becoming trapped between the trays. This prevents collisions and even system downtime.

"Our new series is based on proven technologies with key components such as the steel sorter frame or contactless energy transmission instead of the usual conductor lines," explains Stephan Heessels, global director of the Logistics Systems business field at Beumer. This allows users to reduce the maintenance effort on the machine and wear. The dust that occurs with conductor rails is also avoided. The permanent, wireless communication based on W-Lan enables data transmission in real time - in contrast to infrared communication, where data is only sent when an infrared sensor point is passed.

With the BG Sorter, the communication time can therefore be limited to milliseconds and discharge profiles can be adjusted in real time. W-Lan communication also enables gentle handling of very different products: The operator can add, select and change discharge profiles at any time without having to adapt the hardware. In addition, ejection at different ejection speeds is very precise.

With the BG Sorter, Beumer has placed great emphasis on low maintenance and servicing costs. With the condition monitoring and the extended diagnostic tools, the responsible employee recognizes impending faults at an early stage. This has a positive effect on life cycle costs. The sorter is easily accessible for maintenance. However, the developers have not only designed the new system to be compact. The design allows users to make effective use of the space above and below the system.

Innovative carriage kinematics

For the carriage system of the BG Sorter, a completely new type of carriage with two pivot points per carriage and rollers and guide rollers permanently mounted on the axles was developed. The advantage of this patented solution is, on the one hand, the possibility of smaller curve radii with the same pitch compared to conventional carriage geometry and, on the other hand, a significantly reduced polygon effect in the curves, which leads to lower vibrations in the system. This reduces noise emissions and increases the service life of the system.

The BG Sorter also features larger rollers specially developed for it than for comparable systems. On the one hand, they have significantly reduced the rolling resistance, which is directly reflected in lower energy consumption, and on the other hand, they increase smooth running and reduce noise emissions.

Energy-efficient drive

The series is available with the Optidrive based on servo drives or with the contactless linear synchronous motor (LSM) as the drive system. Both reduce energy requirements and_{CO2 emissions}. Optidrive is a patented friction-locked drive solution that offers an economical alternative to the asynchronous linear motor drives often used in high-performance sorters. The special feature: The contact pressure of the drive wheel adjusts automatically depending on the required drive force - even when braking. This increases efficiency to up to 85 percent and extends the service life of the drive wheels. The synchronous linear motor drive (LSM), which is also energy-efficient, offers the advantage that the moving parts do not come into contact with each other, meaning that there is no wear and tear without sacrificing speed, performance and reliability.

Cross-belt design increases performance and safety

As a cross-belt sorter in the CB version, the BG Sorter achieves a high throughput with a speed of up to three meters per second. The load capacity is up to 50 kilograms per cross-belt conveyor. "Depending on the throughput and product mix, we can configure the system with one cross-belt conveyor per carriage or with two or three conveyors," explains Stephan Heessels. "This allows us to sort different product ranges up to a size of 1,500 by 1,000 millimetres." Particularly with different product sizes, the system's performance can be increased by configuring it with several cross-belt conveyors compared to a conventional configuration of the sorters with just one cross-belt conveyor per carriage.

The full cross-belt design takes particular account of the increasing proportion of non-dimensionally stable conveyed goods. Thanks to the maximum belt width, these are safely picked up, transported and accurately discharged.

The piece goods are fed onto the cross-belt conveyors with extreme precision by the new infeed unit. The position of the unit loads on the system is checked after infeed and corrected if necessary so that the products are always optimally positioned.
