The PLC design adds an automatic stop device for abnormalities in the photoelectric sensor

PLC design automation system device has always been the strong service of Longzhong Enterprise.

Provide customers with 100% customized PLC automatic control system design, which can achieve conditional triggering of automatic start-stop control device machines, such as adding automatic sensors to automatically stop devices when abnormalities are detected, and to collect equipment automation data records, System alarm reminder and so on. The automation of the machine equipment system can improve the production efficiency of the factory area for the owner, reduce production or operating costs, and reduce emergency losses due to sudden disasters...etc.

Today We want to share with you a case of PLC design customization:The client is a well-known chain company. He hoped to add a chain detection device to the chain testing machine. During the detection process, if an abnormality is sensed, it can be automatically stopped through PLC programming, and the replacement process must be convenient for the tester to replace the chain.

After going to the site to investigate the factory environment, our Longzhong engineers, based on their experience in many customized PLC design programs requiring system automation engineering, sorted out a list of items that need attention for customers. Among them, the most important environmental problems of production equipment: overall The operating space of the machine is limited, and there is a high probability that the chain will spray oil during operation (environmental oil pollution problem). Therefore, while adding chain abnormality detection and automatic stop equipment functions to meet customer needs, it is also necessary to conceive and solve the problem of oil splashing in this case.

Discuss with the owner about the chain of abnormality detection, how to write automatic detection of abnormality through PLC design program, and the adopted method is to add "photoelectric detection" device. Install the photoelectric sensor on the chain wear-resistant machine, and write the automatic detection control program in the PLC programmable controller. When the infrared light detector on the machine does not sense the chain on the running table, it will be judged as abnormal If it happens, the machine will stop automatically. The device of the photoelectric detection switch is a project that does not require a lot of space. The addition of a small and precise photoelectric sensor not only does not take up space in the operating environment, but also improves the efficiency of production and testing processes. At the same time, it can achieve the intelligent function of detecting abnormalities and automatically stopping.

In order to cooperate with the customer's chain to test the size of the wear-resistant machine, the preparatory work of Longzhong's pre-operation:

✦ Hardware part : The photoelectric sensor hardware part needs to be customized
✦ Software part : The sensing signal of the photoelectric detection switch needs to be set into the customer's existing PLC program design so that it can automatically control the sensing chain

The customer's chain machine equipment is located in a small space, and Longzhong installs photoelectric sensor transmitters and receivers on the chain machine for the customer, reducing the procedures for changing the design of the factory space for the customer. Longzhong writes the PLC automation program design, and uses the abnormal data of the photoelectric detection signal to automatically control the operation status of the equipment through the PLC program, so that the chain wear test machine can automatically stop when it detects that there is no chain abnormality, reducing the damage to the machine equipment. In addition, the engineer designed an iron shield directly above the photoelectric sensor to solve the problem that environmental oil may splash and affect the photoelectric sensor.

The photoelectric sensor abnormality automatic stop device added by Longzhong for the owner overcomes the problem of environmental oil pollution and fully meets the special needs of the owner. It can make the chain wear-resistant test machine stop automatically when the running chain has abnormalities. To reduce the chance of damage to machinery and equipment.
