Weidmüller I/O solutions are used in the automated logistics sorting industry

In order to cope with the two-layer pressure brought about by e-commerce and the epidemic and ensure the efficiency of logistics and distribution, the express group urgently needs to rapidly expand the logistics production lines of its sorting centers and improve the logistics induction and processing capabilities, especially to ensure that the sorting equipment can always run firmly without stopping in the sudden logistics sorting and transportation. It can be said that in the time-sensitive logistics sorting, it is particularly important to deal with emergencies temporarily.

　　In detail, the distributed I/O products next to the conveyor are mainly responsible for on-site signal acquisition and data transmission, which has the advantage of saving wiring and labor costs. However, for distributed I/O, on the one hand, it needs to ensure a stable supply of data input and output in a relatively small space, and on the other hand, it needs to have a certain degree of fault tolerance to support rapid recovery and fault finding.

For this reason, the sorting equipment supplier of the Express Group has fully adopted the overall processing plan of Weidmüller's industry-leading UR20 long-distance I/O and customized interface boards for the cooperative I/O in its logistics sorting system.

In the logistics sorting and transportation system, UR20 long-distance I/O is used to convert the collected field signals into data and send them to the PLC, and then output the PLC control instructions to drive the inverter and motor to transport the express mail to the designated storage location.

Weidmüller's IP20-rated UR20 and customised interface boards offer a range of innovative value benefits for the sorting system, including:

The first is high reliability and fault tolerance. According to this plan, in the face of problems such as downtime caused by relay failure, it is allowed to allow the operator to simply flip the interface board switch and continue the delivery process without causing a rapid backlog of goods.

Since the logistics sorting center is located in the north and south cities that cross the large temperature difference, the I/O product needs a wide temperature planning, Weidmüller UR20 can maintain normal operation in the environment of -20-60°C, and its IP20 protection level can also easily cope with the on-site environment.

The second is to simplify the operation and maintenance operations, especially to easily deal with the high misconnection rate of the electrical wiring of the sorting equipment, repeated line checking and other high-frequency error-prone problems. When there is a problem with the module or the terminal point, the UR20 is prompted by the LED light, and each module supports online hot swapping, which is convenient to split and does not affect the normal operation.

The third is to improve the efficiency and accuracy of wiring. The on-site construction of the production line requires the access of many sensors, and Weidmüller UR20 adopts the PUSH IN wiring method, which can greatly improve the wiring efficiency, and is color-coded to ensure error-free wiring, which helps users to identify each signal channel more intuitively, saving the manpower and cost of wiring and debugging. Compared with the original wiring method, the equipment manufacturer's device timeliness can be improved by more than 50%, and the review and calibration operation time can be reduced by more than 20%.
