Package handling facilities strive for efficiency. The faster they can move parcels through their system, the more packages they can process. One way they achieve this is with automated sorting systems like cross-belt sorters. This innovative technology offers a host of benefits for high-volume package handling operations.
What is a Cross-Belt Sorter?
A cross-belt sorter is a type of automated sorting system designed for the needs of large package handling facilities. It consists of a long series of narrowed conveyor belts positioned perpendicular to the main flow of packages. The individual belts can move left and right to divert packages to the appropriate destination chute or conveyor line.
Cross-belt sorters provide high-speed diverting capabilities not found in belt curves and other simpler sorting equipment. With their narrow perpendicular belts, a cross-belt sorter can handle irregular-shaped objects and varying package weights. The computer-controlled belts swiftly divert each item to its assigned destination without slowing down the overall product flow.
Benefits Of Cross-Belt Sorters
Cross-belt sorters offer numerous advantages for high-volume distribution centres and parcel handling facilities:
1. High Throughput Rates
Cross-belt sorters are designed for speed. With their closely spaced divert belts, they can handle a high volume of packages. Cross-belt sorters can achieve throughputs of over 19,000 packages per hour. This allows facilities to rapidly process large volumes of parcels.
2. Flexible Sorting
Each perpendicular belt on a cross-belt sorter can independently divert packages left or right. This allows for flexible sorting to many different destinations. A single cross-belt sorter machine can have over 190 divert belts and sort to over 450 unique destinations.
3. Handles All Package Types
With their narrow perpendicular belts, cross-belt sorters can handle a wide range of parcel shapes, sizes, and weights. From small envelopes to large irregular boxes, a cross-belt system takes it all in stride. This makes them ideal for facilities with diverse package types.
4. Gentle Handling
The closely spaced belts prevent packages from reaching high speeds. This inherently gentle handling protects merchandise from damage while sorting. Fragile contents arrive safely at their destination.
5. Small Footprint
Cross-belt sorters provide very high throughput for their size. They require significantly less space than other sorting systems with comparable capabilities. This compact footprint makes them ideal for facilities with limited space.
6. Low Noise
With no hard impacts or sharp directional changes, cross-belt sorters operate with minimal noise. This creates a safer, more comfortable environment for facility employees.
7. Easily Reconfigured
Software controls make it simple to reconfigure a cross-belt sorter’s divert assignments. Operations can adapt the system to changing needs with no rewiring or mechanical changes.
When Should Facilities Use Cross-Belt Sorters?
Cross-belt sorters excel in high-density distribution centres and large package handling facilities. They are the ideal solution when:
- Package volumes exceed 10,000 per day
- Multiple diverting destinations are needed
- Package sizes and shapes vary significantly
- Operations require reliable speed and throughput
- Facilities have limited space for equipment
Cross-belt sorters provide the flexibility, speed, and reliability needed in demanding environments. They are the go-to option for high-volume parcel sorting and distribution applications. With cross-belt technology, packages smoothly flow to their destinations.
Frequently Asked Questions About Cross-Belt Sorters
Here are answers to some common questions about cross-belt sorter systems:
Q: What sizes of parcels can a cross-belt sorter handle?
A: Cross-belt sorters can handle a wide range of package sizes, generally from 6-inch x 6-inch small envelopes up to 30-inch x 30-inch larger boxes. Weight ranges run from just a few ounces up to 70 pounds.
Q: How fast can a cross-belt sorter operate?
A: Cross-belt sorters can achieve throughputs of 10,000 to 19,000 packages per hour, depending on the belt length and number of divert destinations. High-speed cross-belt systems are significantly faster than traditional tilt tray or belt curve sorters.
Q: What conveyor widths are available?
A: Cross-belt sorters come in standard widths ranging from 24 inches to over 60 inches. The most common widths are 24, 30, and 36 inches. Wider units handle larger packages.
Q: Can cross-belt sorters handle irregular shapes?
A: Yes. The closely spaced perpendicular belts easily accommodate irregular and uneven shapes. The narrow belts conform to the items rather than forcing them into channels.
Q: How are diverting destinations programmed?
A: A computer control system programs the belt diversion patterns. Engineers can reprogram the destinations as needed for new package routings or seasonal variations.
