Applications on Sorting Machines for Express Delivery
Cross-belt sorting system is made up by connecting the main driving belt conveyor and a trolley (aka small car) that carries a small belt conveyor. When a small car moves to an assigned sorting spot, the belt rotates to complete the sorting task and sending out items.
Cross-belt sorting system is suitable for sorting various types of small items, such as food, cosmetics, clothing, and more. It is mainly used for e-commerce supermarket, express delivery, and postal system.
The length of the system loop is equally assigned based on the amount of the small car. Once the system is operating stably, it then positions a fixed point on the loop. During the operation, 5 I/O's are used to real-time monitor the operating speed of the loop, so that the system can record current location of each small car.
When the sorting starts, two cameras at the placement station monitor two areas and the placed items. The control system marks and moves the empty small car to the designated spot, and the placement station controls the placement conveyor that transports items to the accelerated conveyor belt. Then the accelerated conveyor further sends the items to the constant-speed conveyor belt. Finally, the conveyor belt shifts to the meeting point along with the small car to complete the placement task at the delivery station.
At this time, the belt on the small car runs and receives the sent items that are moved to the middle of the belt. When the belt on the small car stops going further and arrives at the sorting spot, it runs forward/reverses to transport items to the sorting spot and completes the sorting task.
