In the modern society with a wide range of goods, plastic products have become a common product in people's lives. Therefore, the machines for manufacturing plastic products, injection molding machines, are increasingly appearing in various types of factories. Dedicated robotic arms have also been used more widely. The robot arms for injection molding machines are very complicated to sort according to the types of materials they pick up, the shape of the materials, and the needs of the process. It is mainly composed of four mechanisms: the main arm, the auxiliary arm, the lead puller, and the horizontal traveler. The lower end of the main arm is connected with the tray for gripping the main part of the plastic product, and the lower end of the auxiliary arm is connected with the fixture for gripping the material part of the plastic product (material head: the surplus part left over from the injection molding product). The function of pulling and pulling is to extend the main arm and the auxiliary arm into the working surface of the injection molding machine, and then to transport the formed product to the designated position by the transverse section. The control system uses Yaskawa Motion Controller MP2300 and Pro-face man-machine interface GP/ST3000 series. See the system diagram. In addition, when users use Pro-face products to connect with Yaskawa Electric products, they can also use very effective functions: Pro-face designed a wide range of example components for a wide range of controllers on the market for users to download from the Pro-face website during screen programming, such as the example components of the Yaskawa Electric MP2300 (see Figure 1), Pro- Face configures the communication parameters related to the MP2300 and GP/ST3000 series. The customer can select the MP2300 part directly during screen programming, which can greatly shorten the time of screen programming and directly read through the GP/ST3000 series human-machine interface without programming. Write or monitor the corresponding parameters of the MP2300 series (see Figure 2 and 3). Fig. 1: Yaskawa Electric MP2300 Series Example Parts Figure 2: Yaskawa Electric MP2300 Series Example Parts Figure 2: After reading through the pre-designed example components, you can directly read the values ​​of the registers of the MP2300 series registers and modify the data of the registers that are allowed to be written. Figure 3: Yaskawa Electric MP2300 Series Example Parts Fig. 3: The MP2300 series status and alarm error messages can be directly monitored by pre-designed example parts. Fig. 4: PLC program without PC transfer Pro-face's “Through Function†(see Figure 5) enables easy commissioning of the PLC ladder program through the GP/ST3000 series human-machine interface, thus enabling PLC commissioning to be performed at any location, with Yaskawa Electric products. For example, Pro-face's GP/ST3000 series human-machine interface is used to connect the MP2300 series controllers of Yaskawa Electric. The engineers can directly debug the ladder diagrams of the MP2300 series controllers through the man-machine interface through Ethernet on the office computer. Real-time adjustment of data changes due to changes in production plans. Figure 5: Pro-face "Through Function" In this application case, the Pro-face HMI and Yaskawa Motor Controller were used to make the electrical system simple and uniform, complete in function, and the machine also had better maintenance for the customer, which greatly improved work efficiency. Floating Ball Level Controller The floating ball liquid level controller is composed of floating ball, plug rod, etc. It is installed on the top of the container through the connecting flange, and the floating ball floats on the liquid level according to the principle of equal volume of liquid. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry spring of the floating ball liquid level controller is magnetically attracted to change the liquid level position into an electrical signal, and the actual position of the liquid is digitally displayed through the display instrument, Floating ball liquid level controller to achieve remote detection and control of liquid level.

The floating ball liquid level controller is designed according to Archimedes' buoyancy principle. When the liquid level of the container changes, the floating ball also moves up and down. Due to the magnetic effect, the dry reed of the floating ball liquid level controller is magnetically attracted, so that the resistance in the sensor changes linearly, and then the converter converts the change of the resistance value into 4mA ~ 20mA standard DC signal output, Realize the remote detection and control of liquid level.
