LM in the application of firecrackers drum machine control system

LM in the firecrackers drum machine control system, the application of Zhou Zijian welcome to e hall exhibition hall 3 PLC controller PLC programmable controller, PLC programming cable. 。 。 1 introduction in China is the world's fireworks production country, products are exported to more than 100 countries and regions, only in the 'township of fireworks liuyang, the output value of 2008 is as high as more than 100 hundred million, one of more than 10 billions, become the pillar industry of local economy. Yet as such a long history, huge traditional industries, the present state of production is very backward. As firecrackers industry into the high speed development period in our country, accelerate the fireworks production mechanization, automation production, is the basis of the fireworks industry to increase production and safety in production. China currently firecrackers drum machine control system has two ways, one kind of the gun barrel machine dedicated controller, another kind of PLC control. Due to the special controller is based on single chip microcomputer development, its anti-interference ability and stability than the PLC, and this is particularly important for the continuity and stability of the firecrackers production. 2 system design of firecrackers drum machine action mainly include: paper, pressure roller, paper, roll, add water, add glue, paper cutting, cutting drum, into the tube lamp series of working procedure. According to the characteristics of the process, the PLC control program has manual and automatic control of two control modes. In manual control mode, can be individually control action of every working procedure; When the switch to automatic control mode, the PLC program will be according to the preset process to control the reel machine work, don't need human intervention. All of these manual/automatic signal and hand switch is carried out by the touch screen. System working process: 1: electricity, Electricity check, tube original place, pushing tube withdrawal limit, lower limit roller bit, whether paper lower limit in the original position) 2: start ( Condition: electricity check is normal, manual/automatic switch in the automatic position) The first paper (3: Requirements: speed is adjustable, can achieve 500 mm in length, delay) 4: press roller ( Requirements: first paper length, delay) Hold paper (5: Requirements: roller action is completed, delay) 6: the drum, the second paper ( Requirements: hold paper action is complete; The roll of paper and paper are required to have delay, feed length to set the length of the roll of paper machine stops running; Paper length request reaches more than 3000 mm, the second feed speed adjustable) 7: paper cutting, Condition: paper length to set length, stops feeding motor and roll of paper; There are time delay; Time is adjustable, time within 1 s, accurate to one decimal places) 8: drum ( Condition: paper cutting action is complete; Time is adjustable, at about 5 s, accurate to one decimal places) 9: cutting drum, paper ( Condition: drum is complete; Paper action completed paper electromagnetic valve action and the lower limit of carry paper cylinder in a magnetic switch is triggered, cut cylinder action; Requirements: the action time of the cutting drum is adjustable, time around 9 s, generally as an integer, cutting drum action delay) 10: roller ( Condition: cutting drum action is complete, cutting drum original magnetic switch light) 11: push the tube into the, the first paper ( Condition: action is complete, under the roller cutting drum original position and press roller floor in situ) 12: push cylinder refund or Condition: push the tube into the limit light) 13: roller: ( Cut tube original place, pushing tube withdrawal limit, roller lower limit, lower limit of a paper in the original position, the length of the first paper reach) Has been in the circulatory system control process is as follows: in the flow chart of 'paper' refers to the length of the paper roll into a gun barrel, in the process of actual control, each node long paper from the paper feed motor ( Stepper motor) To control. Hollysys LM series PLC with pulse output function, can according to the regulations of the PLC controller program output pulse sequence number ( 美国专利商标局) Or the pulse width adjustable periodic pulse signal ( 脉宽调制) , the output pulse sequence through precise control of motor drives stepper motor operation, so as to achieve the control node paper long purpose. In addition, the LM series PLC controller high-speed count function, which can monitor the stepper motor feedback pulse signal, through simple transformation, can monitor in the process of paper long reality. In PLC program, put each pneumatic valve, the operating status of each motor and the running state ( Including the start times and operation time) Recorded and uploaded to the human-computer interaction interface. Man-machine interface design is based on the characteristics of the four application LM series PLC of firecrackers drum machine control system has the following characteristics: stability and safety of PLC and touch screen are passed the CE, EMC testing and can work at the scene of the relatively poor industrial production, a better ability to resist all kinds of bad conditions, it provides the necessary guarantee for continuous production. In addition the system to provide a key emergency stop button, when the scene or equipment failure need to stop production accident can quickly when I was a key to stop operation. Simple operation of the touch screen operation interface is a personal, the operation of the link of each device has a prompt, each step has a corresponding operation instructions, interlock action button will lock each other, enhance the operation safety, reduces the threshold operation. Maintainability for each device in the system to do the failure state, running state and operating state records and save, daily accident tracking and equipment maintenance is easier.
