1、Beer filling, Gland machine PLC control system 1. Intorduction Malt beer production process is divided into manufacturing, manufacturing wort, before fermentation, after fermentation, filtration sterilization, packaging, and so few procedures. Beer filling, Gland part of a packaging machine processe

2、s. The membrane filtration of beer after the pipeline into the rotary Jiugang, then the valve into the bottle of wine, Gland, was bottled beer. Beer filling, Gland machines efficiency and degree of automation direct impact on the level of beer production. Chinas beer industry to meet the increasing

3、scale of production and the demand for beer modern high-speed filling machinery filling the requirements of domestic beer manufacturers are actively seeking to transform the unit or the filling of beer production equipment, making it a good use Performance, advanced technology and high production ef

4、ficiency and operating a safe and secure, low maintenance costs of the modernization of beer filling machine. 2. Filling beer, Gland principle and control aircraft parts Liquid filling machine by filling principle can be divided into atmospheric filler,filling machines and vacuum pressure on the fil

5、ling machine. Beer filling,Gland-filling method used pressure is higher than the atmospheric pressure under the filling, storage of the cylinder pressure than the pressure of the bottle, beer bottle into the liquid on pressure. Technology at home and abroad to achieve the filling line is basically:

6、The Rotary Jiugang the rotating movement, placed in Jiugang slots on the empty bottles through the machinery will be fixed at the upper Jiugang vacuum valve to open, closed Vacuum bottles for good treatment, Bozhuan stem from operating, open the valve of the bottle filling CO2 gases, vacuum convex .

7、Round to open the vacuum valve, the bottle will air mixed with CO2 out of gas, open the valve again, the CO2 gas bottle filling, the filling valve on the pressure valve in the bottle close to back-pressure gas pressure at the open-Jiuye Pingbi into the bottle, through pneumatic or electrical control

8、 filling valve to achieve the filling of beer. Todays advanced international beer filling, Gland machine control system mainly by the photoelectric switch position detection part and take the bottles with, Jiugang speed part, dominated by the PLC, touch screen and other components. Filling, Gland of

9、 the mechanical structure and PLC programmable control devices, frequency stepless speed regulation, human-computer interface, and other modern means of complete automatic control technology, the combination of a mechanical and electrical integration. 3. Controlled part of the programme Many domesti

10、c beer manufacturers are now using the filling, Gland of the control system of uneven degree of automation； button and all the manual switch technology have set up operations in a box on the panel, PLC controller for the majority of Japanese companies or OMRON Mitsubishis early products, equipment c

11、hain of control, less protection settings, plus the beer filling the scene poor environment, humidity, such as contact with the switch contacts serious corrosion, the systems signal detection of the high failure rate, resulting in equipment control system Operation of low reliability, the normal ope

12、ration of equipment, such as short-cycle phenomenon. To the actual transformation of the Dandong Yalu River Brewery Co., Ltd. of filling, Gland machine control system as an example, the transformation of methods to clarify the control of such equipment thinking and ideas, according to the scene of t

13、he actual process conditions, to prepare the operation of the PLC Procedures. For beer filling, Gland control system of the actual situation and in accordance with the actual process conditions at the scene, re-design of the equipment of the PLC control system. This transformation of the same method

14、s and ideas can be applied to other liquids and the transformation of filling equipment. 3.1 system hardware configuration Japans Mitsubishi Corporation to use the FX2N128MRPLC use the system to replace the original 2-OMRONs C60P PLC, the original system of the PLC is due to old models, and computer

15、 on-line communications need to configure special converters, the system need to increase the external I / O input points , The extension of spare parts more difficult to find. FX2N128MRPLC is an integrated 128-point I / O controller of the box, a computing speed, command rich, high-cost performance

16、, on-line programming simple and easy extension of the advantages of the Mitsubishi FX series, features the strongest small controller .
