Abstract
The utility model discloses a multi-pole synchronous frequency-conversion speed-regulation drive control device, which is composed of a control cabinet, a driving motor, a speed feedback device, a programmable controller and a frequency converter. The frequency converter can output control signals to the driving motor; feedback signals can be fed back to the A/D input end of the programmable controller through a current feedback device; the D/A output end of the programmable controller outputs the feedback signals to the frequency converter. Having the advantages of strong versatility, simple maintenance, convenient operation and perfect protection functions, the utility model can drive and control a plurality of postal machines and can complete a plurality of multi-pole drive control working according to needs of use.
Description
The utility model relates to the multipole synchronous frequency conversion speed governing driving control device that uses on a kind of mailing machine, belongs to Mechanical Driven control field.
At present; in existing mailing machine field; its driving control device generally all is that one pole drives; and need the mailing machine of the two poles of the earth or multipole driving for some; existing multipole driving control device but exists shortcomings such as not high, the synchronous adjustment of synchronization accuracy is inconvenient, driving defencive function imperfection, and its scope of application is very narrow.
The purpose of this utility model is: a kind of multipole synchronous frequency conversion speed governing driving control device that can be applicable to multiple mailing machine is provided.
The utility model is to constitute like this: it is by switch board (1), drive motor (2), speed feedback device (3), Programmable Logic Controller (4) and frequency converter (5) are formed, Programmable Logic Controller (4) and frequency converter (5) are housed in switch board (1), frequency converter (5) outputs a control signal to drive motor (2), the feedback signal of frequency converter (5) feeds back to the A/D input end of Programmable Logic Controller (4) by current feedback unit (6), the D/A output terminal output signal of Programmable Logic Controller (4) is to frequency converter (5), speed feedback device (3) is made up of speed measuring motor F or rotary encoder TR, the turn signal of drive motor (2) passes to speed feedback device (3) by the rotating shaft of gear train or controlled machinery (7), the signal of the speed measuring motor F of speed feedback device (3) passes to another A/D input end of Programmable Logic Controller (4), the rotary encoder TR output signal of speed feedback device (3) is to the counting mouth terminals of Programmable Logic Controller, three input end A/D5 of Programmable Logic Controller (4), A/D6, A/D7 respectively with potentiometer R1, R2, the adjustable side of R3 links to each other, R1, R2, R3 also connects direct supply E, drive motor (2), speed feedback device (3) is contained on the controlled machinery (7).
Owing to adopted technique scheme, the utility model is compared with existing mailing machine driving control device, machinery for the multipole drive controlling of needs is easy to realize multipole control, and adjusts easily, has the advantage of higher synchronous precision and stronger versatility.During use, as required one or more drive motor (2) and speed feedback device (3) are installed on the machinery (7) that needs to drive and control, to be installed in drive motor (2) on the machinery (7) again is connected the back and is connected with Programmable Logic Controller (4) with the frequency converter that is mated (5), speed feedback device (3) is connected on the Programmable Logic Controller (4), and the action that will finish according to this machinery parameter of adjusting current feedback unit (6) and potentiometer R1, R2, R3 respectively can reach the purpose of multipole drive controlling then.The utility model not only has can drive and control the advantage of multiple mailing machine, safeguards the advantage simple, easy to use, that defencive function is fairly perfect but also have, and it can finish the work of multiple multipole drive controlling according to the needs that use.
