Uniformly linear winding speed governing system
Technical field
The utility model belongs to control convenience technical field, relates to uniformly linear winding speed governing system.
Background technology
Reel system is a kind of conventional control system, is widely used in the production processs such as plastics rolling, iron and steel, packaging, papermaking, printing, dyeing and weaving.It requires that system can control linear velocity when material strip runs on equipment continuously, and can effectively will control in the speed range of regulation, comprises acceleration, slows down and travel at the uniform speed.
Commercial production often adopts closed loop control system, by the actual (real) thickness value of thickness transducer direct-detection material strip, then tachometer value is converted to speed feedback signal to controller, by comparing with the tachometer value preset, calculate control signal, even if automatic control performance element actual speed value is equal with given rotating speed value, thus reaches the stable object of linear velocity.
At present uniformly linear winding is must be obligato aborning, and the current uniformly linear reel system precision of enterprise is low, poor for different adaptability for materials.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the utility model is described in detail.
The utility model as shown in Figure 1, comprise micro controller system 1, micro controller system 1 connects touch-screen 2, rolling DC speed regulator 3 respectively by circuit, unreel DC speed regulator 4, rolling coder 5, unreels coder 6, rolling DC speed regulator 3 and rolling coder 5 are connected winding motor 7 pairs of DC motor speed regulatings respectively by circuit and to rotating speed coding, unreel DC speed regulator 4 and unreel coder 6 and to be connected respectively by circuit and to unreel motor 8 pairs of DC motor speed regulatings and encode to rotating speed.
Described micro controller system 1 model is Siemens Company 200 series of PLC, and CPU is S7-222; Described touch-screen 2 is that prestige human relations MT6070I touch-screen is as operation interface; Described rolling DC speed regulator 3 is Continental Europe DC controller 512c with unreeling DC speed regulator 4 model; Described rolling coder 5 is ASP40-1200-C3 with unreeling coder 6 model.
Winding motor 7 and unreeling motor 8 has all been installed rotary encoder and has been carried out actv. to rotating speed and measure and feedback, the control by permanent velocity of take up roll: micro controller system 1 controls rolling DC speed regulator 3, unreel DC speed regulator 4 carries out a speed governing every the t time to winding motor, realizes the control by permanent velocity to take up roll.
Micro controller system 1 adopts SIEMENS PLC S7-222, and touch-screen 2 adopts capacitive touch screen, has both met industry spot reality, can represent advanced manufacturing industry developing direction again, is easily understood and is easy to operation.First on touch-screen 2, carry out running velocity (linear velocity) setting, be provided with " unreeling coil diameter ", " rolling coil diameter ", " material thickness ", " running velocity " 4, namely feasible system uniformly linear winding runs.
The application be also advantageous in that by PLC micro controller system of the present utility model, saves the investment of frequency converter.And select PLC micro controller system as controller, when selecting other hardware, only needing the equipment selecting international standard interface, being convenient to the change of the expansion of system.
The above is only to better embodiment of the present utility model, not any pro forma restriction is done to the utility model, every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
