Cross Belt Sorter

Cross belt sorter (RKSORT-CBS) provides a reliable solution for efficiently sorting items of various sizes, such as parcels and cartons. The cross belt sorter consists of tracks, carts, cart belts, recognition systems, communication systems, and other components. The carts are connected end-to-end on the track and move in parallel to form the mainline. The mainline intersects with the belts on the carts, hence the name "Cross Belt Sorter." During operation, items to be sorted are placed on the cart belts manually or automatically. When the carts reach the sorting destination, the control system sends a signal to drive the belts, completing the task of sorting and sending out the items. Depending on the layout, cross belt sorters are categorized into circular and linear types. Circular cross belt sorters feature a flat circular layout, with a mainline speed of up to 2 meters per second and a sorting efficiency of 22,000 items per hour. Linear cross belt sorters have a linear layout, with a mainline speed of up to 1.5 meters per second and a sorting efficiency of 8,000 items per hour. Cross belt sorters are widely used in various sorting facilities requiring high efficiency, multiple sorting directions, and strict space requirements, such as express delivery, e-commerce, clothing, food, cosmetics, airports, and pharmaceuticals.

Roller Conveyor

The Realkey Roller conveyor (RKCONV-RC) can be categorized into powered roller conveyors and gravity roller conveyors based on their driving methods. Roller conveyor lines can easily connect and transition with each other, allowing the formation of complex automated logistics conveyor systems when combined with multiple roller conveyor lines and other types of conveyors or specialized machines. RKCONV Roller Conveyors are primarily composed of driving rollers, free rollers, frames, and control system. They are simple in structure, highly reliable, and easy to use and maintain. RKCONV Roller Conveyors are suitable for transporting various items such as boxes, bags, and pallets. For bulk materials, small items, or irregularly shaped items, they need to be placed in containers or on pallets for transport. RKCONV roller conveyors generally come in the following types: Flat Roller Conveyor Flat roller conveyors are flexible to use and cost-effective, making them the most commonly used material transport method. Curved Roller Conveyor The turning angle of a curved roller conveyor can be set to 30°, 45°, 60°, 90°, 180°, or any other desired angle. The turning radius can be specifically designed according to the plan, allowing the creation of more complex conveyor systems when combined with other conveyor lines. Center-Aligning Roller Conveyor Featuring rollers arranged at a certain angle in two rows, center-aligning roller conveyors adjust the position of items to the center of the conveyor line. They are commonly used in the preprocessing section before sorting (usually placed after singulation equipment) or in conveyor sections where the position of items needs to be precisely controlled. Side-Aligning Roller Conveyor Side-aligning roller conveyors adjust the position of items to one side of the conveyor line. They are typically used in conveyor sections where precise positioning of items is required during logistics transport. Accumulation Roller Conveyor Also known as buffer conveyors, accumulation conveyors allow goods to stop and accumulate on the roller line without significantly increasing the overall resistance of the conveyor system. Accumulation conveyors enable automatic and orderly transmission of items, greatly enhancing production efficiency. Merge Roller Conveyor Merge conveyors allow items to be injected into the target conveyor line from different angles, with common merge angles being 45° or 60°. They can form more complex conveyor systems when combined with other conveyor lines. 90° Pop-up Transfer Conveyor The 90° Pop-up transfer conveyors are typically balanced by four support points and can achieve automatic control for 90° turning of items. In limited space conditions, 90° Pop-up transfer conveyors can achieve 90° turning transport, offering the advantage of space-saving.
