Abstract

The utility model relates to a float glass cold side rate tracking and adaptive control device, which is composed of a touch screen (1), a programmable logic controller (PLC), a high speed counting module (3), a 1# rotary encoder (4), a frequency changer (5), a roller way synchronous motor (6) and a rotary 2# encoder (7). The 1# rotary encoder is connected with a last roller of an annealing kilnroller way through a transition gear, transmits detected pulse signals to the high speed counting module, conducts a series of calculation and conversion with the PLC, transmits speed signals to the frequency changer, is connected with the roller way synchronous motor and drives a cold side roller way to rotate. Simultaneously, the rotary 2# encoder is arranged on the cold side roller way, feeds back actual detected rotating speed signals to the frequency changer and conducts speed verification. The two encoders are respectively used for measuring original speed value and speed value after execution, synchronous rotation of a front roller way and a back roller way is achieved through comparison operation of the PLC and the frequency changer. The float glass cold side rate tracking and adaptive control device is simple and reliable in control theory, strong in adaptive capability and convenient to operate.

Description

Float glass cold junction speed Tracking and adaptive controller

Technical field

The utility model relates to float glass equipment electrical control field, specifically is float glass cold junction speed Tracking and adaptive controller.

Background technology

The combined workshop's cold junction rollgang that uses in the float glass process is one of equipment special of float glass moulding, a kind of float glass cold junction rate servo that present domestic glass factory uses, generally be to use a rotary encoder to be installed on the floatation glass production line annealing kiln roller-way, be used to gather the speed of annealing kiln, its shortcoming is because velocity error and the synchronous motor coil error that frequency converter itself exists, and machine error such as wheel box, there is deviation in the actual speed of roller-way before and after making, cause the glass wearing and tearing, even it is damaged, influence ordinary production, its Technological adaptability is restricted.Extensively retrieve at the problems referred to above, still find no improvement project this problem.

The utility model content

The purpose of this utility model is for the bigger shortcoming of error that existing floatation glass production line annealing kiln roller-way control device exists, a kind of float glass cold junction speed Tracking and the adaptive controller that provide are provided.

To achieve these goals, the utility model has been taked following technical scheme:

Float glass cold junction speed Tracking and adaptive controller, it is characterized in that it is made up of PLC, high speed counting module, frequency converter, 1# rotary encoder, 2# rotary encoder, the 1# rotary encoder links to each other by the gear on last root roller of transition gear and annealing kiln roller-way, and the signal output part of 1# rotary encoder links to each other with high speed counting module; The 2# rotary encoder is installed on the cold junction roller-way, and the signal output part of 2# rotary encoder links to each other with frequency converter, and the output of frequency converter is connected to roller-way and carries out synchronous motor.Touch-screen is set to link to each other with PLC.

Float glass cold junction speed Tracking and adaptive control system, it is by touch-screen, PLC, high speed counting module, the 1# rotary encoder, frequency converter, the roller-way synchronous motor, the 2# rotary encoder is formed, the 1# rotary encoder is installed on last root roller of floatation glass production line annealing kiln roller-way indirectly by transition gear, help to improve the stability of measurement data like this, the pulse signal that records is passed to high speed counting module, after PLC process series of computation and conversion, rate signal is passed to frequency converter, after the inner commutation inversion control of frequency converter, be connected to roller-way and carry out synchronous motor, drive the cold junction roller-way and rotate; The 2# rotary encoder is installed on the cold junction roller-way simultaneously, is used to measure the actual speed of roller-way, gives frequency converter with signal feedback, carries out the speed verification, and from motion tracking annealing kiln speed, touch-screen can be revised technological parameter, makes this system's adaptive faculty stronger.

The utility model adopts technique scheme, and its advantage is:

1. the utility model uses two rotary encoders, separately measures, and control principle is simple and reliable, the tracker velocity-stabilization.

2. realized avoiding because the roller table speed inconsistent glass that causes in front and back weares and teares even be damaged, the speed synchronization stable performance.
