First, the control system design

The mechanical system part is designed only to design the mechanical part of the fully automated magnetic surround machine system. The complete fully automatic winding machine system also includes an electrical control part. In the automatic control system of the automatic winding machine we designed, the main function of the electrical control is to realize the motion planning of the whole system, including: motion control of the actuator, information processing of the sensor and human-computer interaction of the field personnel. It is mainly divided into the following units to complete:

PLC control unit, human-machine interface unit, sensing detection unit, execution unit and alarm device unit.

Second, automatic winding machine system flow chart

The PLC flow chart is also called a sequential function chart. The so-called sequential control is to automatically and orderly operate the various actuators in the production process according to the order of the internal state and time according to the pre-specified order of the production process.

The electrical control part of the fully automatic winding machine system we designed is relatively complex, and the entire system control is the responsibility of the company's experienced electrical engineers. In order to facilitate the smooth preparation of the PLC program, we have given a systematic flow chart of the overall motion of the fully automatic winding machine, and the flow chart is relatively long.

Third, automatic winding machine pneumatic system design

1. Pneumatic system composition

A typical pneumatic transmission system consists of four parts: a pneumatic generating device, an actuator, a control element, and an auxiliary component.

1) Gas source

The air source is the power source of the pneumatic transmission system and is the compressed air generated by the air compressor. In order to ensure the normal operation of the pneumatic system, the compressed air must be cooled, purified, decompressed, stabilized, and supplied with oil mist. Therefore, a compressed air purification device must be provided, including a cooler, a water separator, and a gas storage tank. Wait.

2) Actuator

The actuator is an energy conversion device that uses compressed air as a working medium and converts the pressure energy of compressed air into mechanical energy. The actuator includes: a cylinder that performs linear reciprocating motion, a gas motor that performs continuous rotary motion, and a non-continuous rotary motion. Rotate the cylinder, etc. The actuators we are involved in are linear reciprocating cylinders and rotary cylinders and slewing cylinders.

3) Control components

Control elements, also known as steering, arithmetic, and detection components, are used to control the pressure, flow, and direction of flow of the compressed air to allow the actuator to perform predetermined motion patterns. Control components include: various pressure valves, directional valves, flow valves, logic components, fluidic components, stroke valves, converters, and sensors. The control elements we use are directional valves and sensors.

4) Auxiliary components

Auxiliary components are some of the equipment needed to purify, lubricate, silence, and connect components between compressed air. Auxiliary components include: water separators, oil mist, muffler and various piping accessories.
2, automatic winding machine system electromagnetic reversing valve selection

The reversing valve is a very important type of valve in pneumatic control, which is used to change the direction of the airflow and control the on and off of the airflow in the pipeline to control the direction of movement of the actuator. The electromagnetic reversing valve utilizes electromagnetic force to complete the movement of the spool to realize the reversing function. Since the solenoid valve is electrically operated, it is easy to cooperate with control devices such as PLC, and thus has been widely used.

According to the requirements of the automatic winding machine system, there are two types of solenoid valves, three-position five-way solenoid valves, and the other two-position five-way solenoid valves. In the selection, the three-position five-way solenoid valve uses the SY5340 series solenoid valve produced by Japan SMC Company, and the two-position five-way solenoid valve model is the SY5140 series solenoid valve.

Features of the reversing valve:

1) Low power consumption: 0.5W;

2) Small, large flow;

3) High-speed response: less than 15 milliseconds;

4) Can be assembled in multiple places;

5) Maximum operating frequency: 10 times / sec.

When one end of the reversing valve is energized, the electromagnetic force generated at this end pushes the pilot valve to open, and the air source is turned on, thereby pushing the main valve to move and completing the designated work. There are manual switches on the valve body to mechanically move the valve core in the event of a power failure.
