客車箱體磷化加工處理程控搬行車電氣控制系統(tǒng)

摘 要

繼電器接觸控制系統(tǒng)是應用最早的控制系統(tǒng)，是由按鈕、接觸器、繼電器等組成的控制系統(tǒng)。作為工廠設備的電氣控制，它具有結構簡單、容易掌握、維修方便、價格低廉等優(yōu)點，多年來在各種生產機械的電器控制領域中，一直獲得廣泛的應用。這種控制系統(tǒng)的特點是：設計、安裝、調整、維修方便，價格低廉，運行可靠。如果要使繼電-接觸器控制線路達到簡便、接線短、元件少、控制速度較快的目的，可利用三菱FX1N系列可編程序控制器來控制磷化自動生產線。磷化過程用PLC控制搬行車來進行磷化加工處理，行車在前后運行及停車時采用能耗制動，以保證準確定位，并且搬行車在每個槽位停留的時間由定時器控制，可根據工藝需要由外部設定。搬行車有多種操作方式，便于實際生產的需要，主要有：自動循環(huán)、單周期、單步操作、手動操作，這四種操作方式。采用PLC對搬行車的工作過程進行控制的方法，簡化了控制系統(tǒng)的接線，提高了系統(tǒng)的可靠性和靈活性，在實際生產中減少了勞動力，提高了工作效率。

BUS BOX PHOSPHATE PROCESSING PROGRAM-CONTROLLED ELECTRIC CONTROL SYSTEMT TO MOVE TRAFFIC

ABSTRACT

The relay touch control system applies the earliest control system, is by the button, the contact device, the relay and so on control system which is composed. As industrial plant equipment's electric control, it has the structure simply, easy to grasp, the service to be convenient, merits and so on low in price, for many years in each kind of production machinery's electric appliance control domain, have obtained the widespread application. This kind of control system's characteristic is: The design, the installment, the adjustment, the service are convenient, the low in price, the movement is reliable. If must enable following the electricity - contact device control wiring to achieve, the wiring to be short easily, the part are few, the control speed quick goal, may control the galvanization automatic production line using the Mitsubishi FX1N series programmable controller. The galvanization process controls with PLC moves the driving carries on the galvanization, the driving when the around movement and the parking uses the dynamic braking, guarantees the accurate localization, and moves the driving to control in each trough position pause time by the timer, may need by exterior to establish according to the craft. Moves the driving to have many kinds of operating modes, is advantageous for the actual production the need, including: Autocycle, monocycle, single-shot operation, manual operation, these four operating mode. Uses PLC to move the driving the work process to carry on the control the method, simplified control system's wiring, enhanced system's reliability and the flexibility, reduced the labor force in the actual production, raised the working efficiency.

KEY WORDS: Relay, Mitsubishi FX1N series, driving, operating mode
