Control System Description控制系统描述The film press control system is part of the hardware and soft ware which provide theoperator controls and the orderly control of the pape

4、r machine functions. The system is based on a control strategy which employs the use of a distributed control system (DCS)along with a programmable logic controller (PLC). In general, the PLC will control machine sequencing, interlocking, and other discrete functions while the DCS will control proce

5、ss loops and tasks of an analog nature. 施胶机控制系统是提供纸机设备功能命令控制及操作控制的硬件和软件设备的一部分。该系统是基于DCS和PLC的一种控制方式。一般说来，PLC是控制机器程序、联锁和其他分离功能，然而DCS是控制流程回路和执行自然模拟量的。The film press has one control desk, where the different functions of the film press can be controlled as per following explanations. 施胶机有一控制操作台，其上的功能控制按

6、键以下有说明There are two working modes for the film press: the production mode and the maintenance mode. The selection is made by the operator on the DCS (or with a key switch). 施胶机有两种运作模式：生产模式和维护模式。可以由操作人员在DCS上选择（或者是用转换开关）- The maintenance mode allows to move the press and heads while the press rolls ar

7、e at Zero speed for maintenance purpose. 在维护模式下，一旦为了维修使施胶辊停止后，可以移动施胶辊和涂布头- In production mode, the presses must rotate and the paper must be full width to allow press and heads to go in waiting and working position. 在生产模式下，施胶辊必须运转及纸页必须是全幅时，才允许施胶辊和涂布头进入等待和工作位置1.1 HYDRAULIC UNIT液压单元The hydraulic unit

8、is used to move the metering heads and the movable press.A screen page is dedicated to the part of the hydraulic unit dedicated to the film press.液压单元是用来移动涂布头和施胶辊的。作用于施胶机的液压单元部分在DCS上有一显示画面1.1.1. Oil temperature油温The oil heating in the tank is turned on by the general ON/OFF switch of the film press

9、located on the control desk. 油箱里的液压油加热是由施胶机操作台上的ON/OFF按钮来打开的The management of the temperature thresholds is done by the temperature sensor acquisition together with some functional thresholds given by hydraulic unit thermostats: 油温界限值操纵是由温度变送器和液压单元恒温器给定的温度界限值共同来实现的- 1st threshold temperature 20 第一界限

10、值 温度20- 2nd threshold temperature 35 第二界限值 温度35- 3rd threshold temperature 60 第三界限值 温度60The key panel (KP) “start ” will be effective only when the oil temperature is high enough (T20). 仅仅当液压油温度高于20是，关键“开始”开关才起作用If the temperature of the oil tank is below 20, the heating will start. It will stop onc

11、ethe temperature is over 35. When the temperature is over 20, the first heating element will stop, only the second one will continue until the second threshold is reached. 假如油箱液压油温度低于20，加热装置工作。一旦温度超过35则加热停止。当起始温度超过20，第一加热元件停止工作，第二加热元件工作至油温达到第二界限值。The minimum low level of the oil tank and the second

12、threshold temperature forbid the heating start-up (th2 60). 油箱的低限液位和第二温度界限值阻止加热元件启动The start-up of the selected pump is obtained by pushing the key panel ( KP) “s tart ”of the hydraulic unit screen page. 通过液压单元显示画面的面板“启动”按钮来实现油泵启动选择1.1.2.Hydraulic pump液压油泵The pump start-up is interlocked by a minimu

13、m temperature of 20C to preserve them. 油泵的启动与20低限油温联锁It will be put out of service by pushing the key panel “s top ” or eventually depending on the fault management错误的操纵和按面板上“停止”按钮将使该联锁失效.The starting of this pump is visualized on the screen by a dynamic symbol.A very low level, or a low pressure re

14、sults in the stopping of the pump.油泵在液压单元画面上有形象动态运行显示。低低限液位，低压力将使油泵停止In case of a pump fault the operator can select the spare pump in the same screen page and operate it the same way as the main pump. An adequate signalization is associated with this selection. 一旦主油泵出故障，操作人员可以选择启用备用油泵，并以操纵主油泵那样启动备用

15、油泵。有一恰当的信号作用与该选择相联系1.1.3 Status状态The 3rd threshold temperature (t60), the tank low level, a plugged filter are indicated to the operator by an alarm.第三温度线，低油位，过滤器堵塞都会有报警信号显示给操作者-The status of the hydraulic unit pump and temperature can also be read from the film press” screen page. 可以通过“施胶机”画面读取液压单元

The press can go from the service to the waiting position only if the presses are in rotation.在等待位置下，可移动施胶辊接触固定辊。只有当施胶辊处于运转状态时，其才能从

18、维护位置进入到等待位置- In working position the hydraulic micrometric stops FS/DS retract to put the Nip at the target pressure (10 to 60 daN/cm). 在工作位置下FS/DS液压测微站动作使压区压力达到目标值（1060daN/cm）- The status of three electrovalves related to the press motion/loading canbe read at the bottom of the ”electrovalves film
