PLC-based Control of Automatic Production Line Teaching Equipment

In order to adapt to the needs of teaching, to make students master the application of PLC in the industrial automatic production line, Dolang developed many PLC-based teaching equipment of production Line. Our automation production line integrates a variety of technical knowledge, such as pneumatic control technology, mechanical technology, sensor application technology, PLC control and networking, stepper motor control and inverter technology to simulate a very close to the actual production control process. Now we introduce the automatic production line teaching equipment structure, working process and PLC control realization. With PLC to control the automation of production lines such a more complex production equipment, is the ideal choice. (More PLC trainer information, please visit http://www.dolangeducation.com/plc-training-series/)

The structure of the automatic production line teaching equipment. Automatic production line installed in the aluminum alloy rail training platform, from the supply station, assembly station, processing station, transmission station and sorting station composed of five workstations, the composition of the structure such as Figure 1 shows. The workstation are set up a Siemens S7-200 series PLC to assume its control tasks, the specific model of the PLC marked on the map. In addition, the aluminum electrolytic capacitor assembly automation production line equipment is a set of semi-open type of equipment, the user to a certain extent, according to their own needs to select the number of units composed of equipment, type, up to five workstations, Can be self-contained as a separate control system.

The workstations in the equipment are placed on the training platform to facilitate the demolition and installation of various mechanical parts and pneumatic components, control wiring, pneumatic solenoid valves and tracheal installation. Among them, the conveyor station uses the most flexible disassembly module structure: the composition of the unit button / indicator module, power module, PLC module, stepper motor driver modules are placed in the drawer module placed on the shelf between 1 modules , The module and the training platform between the terminal block connection using secure wire connection, to meet the requirements of a comprehensive training to the maximum.

Automatic production line training teaching equipment work flow: feeding station for the material, the aluminum shell (by the black and white two colors of plastic parts instead) automatically sent to the material table, by the transport station of the robot will be caught aluminum shell To the assembly station of the material table, the assembly station will be prime (replaced by small cylindrical plastic parts) embedded aluminum shell after the assembly, and then by the transmission station of the robot will be assembled with a good workpiece to the processing station under the stamping mechanism to complete a stamping After the machining operation (the closing of the colloidal particles), and then the workpiece is picked up by the robot of the conveyor station. The conveyor belt sent to the sorting station is sorted. The finished product is sorted to make the finished black and white workpieces From different troughs. The conveyor station is an automated production line that is important and is also responsible for the work of the complex value of the workstations, the robot is a can achieve four degrees of freedom movement (ie, rise and fall, out of retraction. Clamping release and rotation) Which is mounted on the slide plate of the stepper motor drive unit and is reciprocated by the drive assembly to precisely locate the material table of the designated workstation. The workpiece is transported to the designated location on the material table. lay down. The stepper motor is driven by a stepper motor driver. The pulse signal and the driving direction signal are controlled by the PLC of the conveying station. In the sorting station, the asynchronous motor is used to drag the conveyor belt to convey the material. The speed and direction of the asynchronous motor are controlled by the integrator, and the start and stop of the inverter is controlled by the sorting station PLC.

Automatic production line teaching equipment control system using STEP Micro / WIN V4.0 programming software. This is a programming tool designed specifically for the Siemens S7-200 series of small PLCs, providing a good programming environment for users to develop, edit and monitor their own applications. It is easy to learn, to solve the complex automation tasks, while supporting STL, LAD, r, '8D three programming language officer, the user can according to their own preferences at any time between the three switches, the package provides no room to help Function, even if the beginner can easily get started, including multi-language official package, you can easily switch between the language version, with password protection, to protect the code from others operation and destruction. The use of the software can be prepared according to the requirements of the control system to complete the control program with the PLC real-time communication, the program download and upload and online monitoring.

PLC control system communication

S7-200 communication interface for the RS-485, the communication protocol using the PLC comes with standard PP! Protocol for data communication. In the use of PPI protocol for communication, only a PLC or other equipment as a communication initiator, known as the master station, other PLC or equipment can only passively pass the meal or receive data, called the slave. In the aluminum electrolytic packed container assembly automation production line, 5 PLC control 5 workstations, so need to set up five PLC network, to achieve 5 PLC data transfer between the completion of automated production line automatic control. In the network, specify the rotation station as the master station, the remaining stations for the station. Each PLC through the RS-485 serial communication to achieve interconnection, constitute a distributed control system.
