An automatic sorting machine is a key piece of equipment in an automatic sorting system. It requires a mechanical transmission line ranging from 40-50 meters to 150-200 meters in length, as well as a supporting mechatronics control system, computer network, and communication system. This system not only occupies a large area, but also requires a 3-4 story high-rise warehouse and various automated handling facilities (such as forklifts) to match it.
The automated sorting system operates as follows: The logistics center receives tens of thousands of different goods daily from hundreds or thousands of suppliers or cargo owners via various transportation methods. These goods are unloaded and quickly and accurately sorted according to product type, cargo owner, storage location, or destination in the shortest possible time. The goods are then transported to designated locations (such as designated shelves, processing areas, or shipping platforms). Simultaneously, when a supplier or cargo owner notifies the logistics center to ship goods according to delivery instructions, the automated sorting system accurately locates the goods to be shipped from the vast high-rise shelving system in the shortest possible time and issues the required quantities. Different quantities of goods retrieved from different storage locations are transported to different sorting areas or distribution platforms according to their delivery destinations for loading and delivery.
Equipment Introduction
An automated sorting system generally consists of a control device, a sorting device, a conveying device, and sorting lanes.
The control device's function is to identify, receive, and process sorting signals, instructing the sorting device to automatically classify goods according to product type, delivery location, or owner category based on the requirements of the sorting signals. These sorting requirements can be input into the sorting control system in various ways, such as through barcode scanning, color code scanning, keyboard input, weight detection, voice recognition, height detection, and shape recognition. Based on the judgment of these sorting signals, the system determines which sorting lane a particular product should enter.
The function of a sorting device is to change the direction of travel on the conveyor system and allow goods with the same sorting signal to enter other conveyors or sorting lanes when they pass through the device, based on sorting instructions issued by the control device. There are many types of sorting devices, generally including push-out type, floating type, tilting type, and branching type. Different devices have slightly different requirements for the packaging materials, packaging weight, and smoothness of the bottom surface of the packaged goods.
The main component of the conveying device is the conveyor belt or conveyor. Its main function is to allow the goods to be sorted to pass through the control device and the sorting device. On both sides of the conveying device, several sorting lanes are usually connected so that the sorted goods can slide off the main conveyor (or main conveyor belt) for subsequent operations.
The chute, typically composed of steel belts, belts, rollers, etc., allows goods to slide from the main conveyor to the collection platform. There, workers gather all the goods at the chute and either store them in a warehouse or assemble them for loading and distribution.
The above four components are connected together via a computer network, and together with manual control and corresponding manual processing steps, they form a complete automated sorting system.
The EN620 series distributed frequency converters are suitable for conveyor systems, driving the nearest motor to power the conveyor belt, achieving stepless speed regulation, and meeting the requirements for rapid start-stop and long-term high-speed and stable operation of the conveyor belt. Multiple EN620 frequency converters can be networked with a host computer and controlled via buses such as EatherCAT, Profinet, and CANopen to achieve fast and accurate material transfer, meeting the requirements for multi-section synchronous transmission and rapid sorting, thereby improving sorting efficiency.
