The sea - for PLC application in the grinding machine production line design Industrial control -

One, the application background due to industrial labor costs rising all over the country, the machine substitution process steadily, in response to national policy, promote the development of industrial automation, our company decided to develop a yituo 2, which has the function of automatic up-down material grinding machine production line, for production of saw blade industry workers 'increase' mechanism reform to provide equipment foundation. The set of grinding machine production line has been by the custom, is a set of grinding production line fully adapt to the needs of customers. Because the workpiece products across the country have a lot of companies in the production, and they all have some business with our company, so the prospects are very broad.

second, the application field of the current equipment has entered the stage of debugging finally, each part of the interlocking interlocking, action has finished debugging, running workholder material detection part appears uncertain factors, running a little slow, mechanical part is still in improvement. The device can realize a manipulator for both material grinding machine. Implementation artifacts during cleaning, flip, measurement, sorting, etc. Equipment has three servo axis, one step shaft and through the switch output control of a three seven asynchronous motor and cylinder. Each action according to the predetermined order, in order to realize the two grinding machine processing at the same time, reduce the pause time, improve work efficiency, reduce the waste of manpower.

3, the solution for this equipment is divided into three parts, two grinding machine and a truss type manipulator, a total of three sets of control system, two sets of grinding machine control system respectively connected to the robot control system, the connection way for the relay switch signals and 485 bus communication, two-way connection to ensure equipment reliability. Each control system for PLC + HMI mode respectively, grinding machine man-machine interface to set parameters, the machining process manipulator with man-machine interface to set operation processes, and displays the current position, and through the RS485 ( Modbus) Share the measurement data information to the corresponding grinding machine, so that grinding machine for purpose of processing, implementation artifacts one-time processing molding.

6, 5, the software design for PLC application summary sea very attentively on the production, from the terminal line of design in order to avoid the connection in sequence when the need to have tight connection circuit solve again to install wiring trouble, directly to wiring in accordance with the order. Removable terminal row, the replacement at the time of trouble. Terminal blocks to remove redundant COM point, the actual use process, there are quite a few COM point is need series together, the sea for PLC is done this in the past, brings great convenience to connection. Input of wide voltage design to save the cost, the transformer without the use of isolation transformer can make PLC stable job. Used for network programming style, clear and easy to do, more readable. Instruction type of module, the register can be in the same picture shows, easy to monitor debug, brought great convenience to the debugging process

Yaskawa inverter wiring diagram to sea for the British witten PLC application in the grinding machine production line design of elevator control system design in the automation control system in the application of IC burning
Wow, this sounds like a bit of a cruel question, but it is a vitally important question to ask yourself if you are struggling with your plc controller price and you would like to stop the plc manufacturers problem.
For more tips and strategies on effective programmable control systems solutions, get your choice at Coolmay PLC.
plc manufacturers allows users to apply in different ways for satisfying their needs.
People tend to want what they perceive they cannot have. Making Coolmay seems exclusive or as if it will go out of stock if they don't act quickly often makes it more enticing to the consumer and increases the likelihood that they will buy in.
The rising plc controller price consciousness observed worldwide are expected to be key factors driving the demand for programmable control systems plc manufacturers.
