Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] In the example of the present invention, an RP fast manipulator is controlled to realize fast picking and handling of metal and iron workpieces. The pick-up fixture selects the electromagnet, and relies on the on / off of the electromagnet to realize the pick-up and discharge of the work material.

[0025] In the embodiment of the present invention, Yaskawa servo motors are used for the rotating shaft pair, electric cylinders are used for the moving pair, and Siemens S7-200 serie...

Abstract

The present invention discloses a PLC-based multi-working procedure universal control method. The PLC-based multi-working procedure universal control method is characterized by carrying out the PLC model selection based on the IO statistics number, gathering the number of the sensors used in each working procedure and writing a PLC address distribution table, wherein a condition relationship of starting the sensors adjacently and orderly is that when the states of some sensors are ON, the corresponding control contacts act to start the next working procedure. According to the present invention, in order to be suitable for the production lines and the automatic processing tasks of different complexities, a shift register-based PLC universal control program is established, all working procedure ladder diagrams are simple and are easy to understand, and the sensor contacts involved in each working procedure are classified; during a control process, and by using a software to observe the ladder diagrams, the action sequence and states of the contacts can be monitored, thereby being visual and being easy to understand.

Description

technical field [0001] The invention belongs to the technical field of numerical control, and in particular relates to a multi-process general control method based on PLC. Background technique [0002] PLC is the most commonly used control device nowadays, and it can complete almost all tasks in the field of industrial control. In fact, the current PLC also has a strong processing ability for analog quantities. Therefore, in most industrial control systems, PLC has replaced industrial personal computer (IPC) as the main controller to complete complex industrial automatic control tasks. At present, the famous PLC manufacturers in the world include AB General Electric Company in the United States, Mitsubishi and Omron in Japan, Siemens in Germany and Schneider in France and so on. Since the PLC was produced, manufacturers have emerged continuously and the varieties have been continuously refurbished, bringing a new round of revolution to the control industry. Since the 1920...
