The stage amounts to the application of mechanical and electrical products on packer of automatic pillow type

Packer of introductive pillow type is a kind of package machine with the wider application in the packing industry such as food, medicine, we are in what many every day object and provision use in daily life to pack is pillow type packer mostly enclose and become. The rapid development as our country economy and flowing water of person the people's livelihood rise smoothly, brought good development good luck to packer industry, applied range is broader and broader also, also raised taller requirement to the character of packer and manufacturing efficiency at the same time. Traditional pillow type packer basically uses difference fast the structure of gear case, the advantage is moving stability; Defect is noise bigger, machinery allows easy damage, the adjustment that encloses precision is very troublesome. As the development of microelectronics technology, computer technology, sensor technology, PLC technology is increasingly mature, application is more wide also. System of this packer lead plane uses PLC to regard control as systematic core, can make the rate that pack high, location is exact, the system is more reliable, stable, accord with, satisfy the development requirement that packs now. Appearanceofpackagingmachine1 of packer whole exterior.

The system is summarized 1.

Packer of type of pillow of 1 system composition basically is finished shape, fixed position, pack and the function such as heal. Basically include share of the following systems: (1) seal those who cut packer of systematic pillow type cut a system to seal a knife by the horizontal stroke (on, below) even if seal,mix (two or so) composition, its action undertakes to packing namely transverse and enclose fore-and-aftly. (2) heat even if Feng Dao undertakes heating,systematic system need is mixed to horizontal Feng Dao, undertake temperature is controlled, use a stage to amount to the temperature that thermometer is collected and controls a cutting tool. (3) knife of transversely of drive of transducer of frequency control system achieves a cut goal, its speed decides the packing rate of this packer. (4) even if seal,send makings system send makings system by servo drive feeding roller, send makings system to cooperate with transversely, wait for technical index to achieve according to packing velar bag to grow accurate send film and can achieve cut accurate (transversely arrives the color patch position of the film that pack) requirement. (5) power source of electric control system uses single-phase 220V/50Hz power supply, the electrical system of lead plane is main wait for composition by interface of PLC, transducer, servo, man-machine. Install to be close to switch on axis of horizontal Feng Dao, the position is horizontal point of tangency; Sending velar axis jacket one photoelectricity switch, effective when cursor of the black on the film that pack is passed; Even if seal the main shaft that sends makings system to install coder of a 360 lines,be in, to bag progress travel plan grows (come true through computation of PLC high speed) . 1.

System of principle of 2 electric control delimits through the correspondence on man-machine interface face setting bag grows (the film that pack the distance between two cursor) , bag long set also can pass bag of the system that start to grow to measure implementation automatically. Press bag is long when measuring pushbutton automatically, servo is started with fixed rate, even if drive seals a system to send makings. Detect when photoelectricity switch the first cursor of the film that pack when begin plan long, stop when running next cursor to come plan long, show the length that computation comes out to man-machine interface. When pressing next memory button, send this length into PLC, as seal the length that film packs when cutting currently, if pursue,1 is shown. The command frequency F that the system uses PLC communication means to collect transducer and output frequency H, through begging the average of these two frequency (the delay time when avoid to collect onefold output frequency according to this) , as the current frequency of transducer. Get the V of current traversal speed of electric machinery through computation, the rotate speed coming back that gives current transversely knife than can be being calculated according to the drive of rigid structure spends R (turn / cent) , as the basis of speed sending film. Graph 1 man-machine interface is installed 2.

Control system is designed 2.

The control of system of 1 control block diagram used a stage to amount to PLC partly, integrated stage amounts to man-machine interface, servo, transducer to wait for those who will realize packer to send expect and accurate enclose, if block diagram is shown 2 times,the system controls a share. Graph 2 systems control block diagram among them, PLC is the core of whole system, undertake signal, data processing, its function decided the character of whole system. The system chose a stage to amount to DVP-20EH, this type has count of high speed of 3 AB photograph (among them two single-phase frequency are wide for 200K) reach pulse of two high speed to output (frequency is wide for 200K) , have function of powerful operation of float check the number and rich circumjacent statement collect [1] . Man-machine interface is given out with the input at parameter and control jussive. The system chose DOP-A57GSTD, its have 16 ash rank show, structure of high-speed strong put oneself in another's position, can come true online / emulate from the line, present what to the user a true just enough uses, the input interface that can plan [2] . Coder is used at providing feedback signal of the position, with transducer (choose a stage to amount to AFD-015S23) , servo (choose a stage to amount to 750W servo controller) , PLC makes system of a closed-loop control [3] . 2.

2 functions come true (1) alignment of automatic transversely position is moved through the dot (even if seal,mix to transversely knife respectively send material point to move) the cursor position that cuts transversely knife just in time in the film that pack, press education mode begins pushbutton next, servo is started with fixed rate, even if drive seals a system to send makings. At the same time PLC begins plan long, when running cursor place, servo sends film to stop, and current plan long data sends man-machine interface current page on. When pressing relative position stores, PLC undertakes packing with current relative position, if pursue,3 are shown. Graph interface of man-machine of 3 automatic transversely is installed (2) when the hand moves transversely position to aim a hand to move an operation, can input relative position on man-machine interface directly; The value of Zun Yihe right shift in moving picture can be carried when moving inputs pushbutton to adjust cutting tool position directly. If pursue,4 are shown. Graph 4 hands move transversely man-machine interface to install (3) cut dog when functional equipment is moving, every run transversely knife a week, point of tangency is close to switch to pass PLC exterior interrupt, collect current coder computation to be worth, undertake comparative with the relative position of the memory in PIC, the size of difference value mixes the basis to be being lost, will calculate the frequency that gives PLC place to give out command pulse. (4) other function passes face plate or man-machine interface can come true start, stop, send material point to move, cutting tool dot is moved, bit more overall move wait for a function, when move, can detect current movement speed, record processes an amount, can realize to clear. 2.

This system can satisfy the last word the moving requirement that the user issues in a variety of circumstances, resolved a few weakness of traditional and mechanical equipment, moving stability, cut accurate, the operation is simple. Amount to the integrated program that dominates a field in labour plus the stage ((used a stage to amount to DVP-EHPLC, stage to amount to VFD-M transducer, stage to amount to servo, coder and stage to amount to) of DOP-A man-machine interface, make this system had very good gender price to compare again, have better market to popularize value.
