      The double-layer staggered groove is a structural optimization and spatial upgrade based on the traditional single-layer groove. Through the innovative design of upper and lower double-layer layout+left-right staggered layout, it achieves significant improvements in sorting efficiency, site utilization, package safety, and operating costs. Compared with ordinary groove, it has the following outstanding advantages:
1、 The space utilization rate has been significantly improved, and the number of sorting compartments of the same area has doubled
      Ordinary chutes only adopt a single-layer layout, and the number of grid openings is strictly limited by the width of the site.
      The double-layer staggered chute fully utilizes the vertical space, and can achieve independent discharge gates on the upper and lower layers under the same footprint. The density of the gates is nearly doubled, effectively solving the problem of tight space and insufficient number of gates in the sorting center, and significantly improving the sorting capacity per unit area.
2、 Misalignment structure avoids package interference and significantly reduces the risk of jamming, stacking, and collision
      If the upper and lower layers of the ordinary chute are arranged facing each other, it is easy to encounter problems such as overlapping package falling paths, air collisions, and package stacking blockages.
      The double-layer staggered chute adopts a left and right staggered drop position, completely separating the downward trajectory of the upper and lower layers of packages without interfering with each other, structurally eliminating package crossing, jamming, and stacking, ensuring a continuous and smooth sorting process, and improving the overall stability of the system.
3、 The package slides more smoothly and has a lower damage rate
      The double-layer staggered chute adopts a reasonable inclination angle and circular arc transition design, combined with staggered buffering to reduce the drop distance, resulting in less impact and more stable posture during gravity sliding.
Compared to ordinary chute direct discharge, it can effectively reduce package impact, deformation, damage, and scratching, especially suitable for high protection requirements such as fragile goods, soft bags, and express small items.
4、 Higher sorting efficiency, significantly increased hourly processing capacity
      Ordinary chutes are limited by the number of grid openings, which can lead to congestion and queuing for material discharge.
      The double-layer staggered chute can achieve independent discharge of both upper and lower layers simultaneously, and can process more orders and packages per unit time. With the design of a centralized packaging area, it reduces the distance for operators to move and improves the efficiency of the entire sorting, packaging, and loading process.
5、 More flexible layout, suitable for high-density, multi category intelligent sorting systems
      The ordinary chute layout is single and difficult to meet the needs of multiple SKUs and high grid density scenarios such as e-commerce, express delivery, and pharmaceuticals.
      The double-layer staggered chute structure is modular and has strong expandability. It can flexibly adjust the width, inclination angle, and displacement distance according to the type of sorting machine (cross belt, balance wheel, slider), and is suitable for mixed sorting of multiple categories such as small items, large items, soft bags, and irregular items. Its applicability is far superior to traditional chutes.
6、 Reduce site and infrastructure costs for better economic benefits
      On the premise of achieving the same number of grid openings, double-layer staggered chutes can save about 50% of the horizontal occupied space, reduce the width of the factory building, steel structure, floor and supporting facilities investment.
At the same time, the system has high stability, low maintenance, and long service life, significantly reducing later operation and replacement costs.
