Technology according to Fig. 3 constitutes below, the control method of automatic reverse winding when the press mold temperature and the method for control speed of plastic packaging machine being described and blocking film.
Fig. 4. be the press mold temperature of plastic packaging machine of the present invention and the flow chart of method for control speed.
The first step of this method is determined the step S410 of press mold thickness.
Determine press mold thickness by control part 320, according to press mold thickness setting press mold temperature, and the actuating speed of setting heated rollers 340.Heating part 330 begins to heated rollers 340 heating, and the temperature of perception heated rollers 340 is with the step S415 of minimum speed CD-ROM drive motor 350.
Second step, but judge whether the temperature of heated rollers 340 has reached the minimum temperature S420 of press mold.
But do not reached the minimum temperature of press mold by the temperature of temperature sensor 360 eddy-current heating rollers 340, control motor 350 is driven into minimum speed, continues heating for heated rollers 340 by heating part 330.
But reached the minimum temperature of press mold by the temperature of temperature sensor 360 eddy-current heating rollers 340, control part 320 is just controlled motor 350 can compensate the speed operation S425 with the temperature difference of design temperature.
Control part 320 control motors are heated to design temperature for the temperature of heated rollers 340, and the temperature difference of CD-ROM drive motor compensation and design temperature and speedup are to setting speed S425.
Third step judges whether the temperature of heated rollers 340 reaches design temperature S430.
Temperature by temperature sensor 360 eddy-current heating rollers 340 reaches design temperature, and the actuating speed of control part 320 control heated rollers 340 and motor keeps S435 within the specific limits.
The 4th step in the press mold process, judges whether the press mold temperature changes S440.
Control part 320 judges that design temperature is to change to high temperature by low temperature, still changes to low temperature S441 by high temperature.
If design temperature is a high temperature by low-temperature transformation, continue to make the temperature after its temperature increases to setting to heated rollers 340 heating; Simultaneously constantly compensation temperature is poor, and the actuating speed that makes motor increases to setting speed S443 by-α.If design temperature is a low temperature by high temperature transformation, end to give heated rollers 340 heating, make the temperature after its temperature is reduced to setting; Simultaneously constantly compensation temperature is poor, and the actuating speed that makes motor is reduced to setting speed S445 by+α.
The 5th step judges whether the temperature change reaches design temperature S450.
Temperature by temperature sensor 360 eddy-current heating rollers 340 reaches design temperature, and the actuating speed of control part 320 control heated rollers 340 and motor keeps S435 within the specific limits.
When Fig. 5 is the design temperature change, the corresponding flow chart of contrary rotation automatically of motor drive speed.
At first set the press mold thickness S510 of plastic packaging machine.
Set the press mold thickness by control part 320, the temperature of heated rollers 340 during according to the required press mold of press mold thickness setting, and set the actuating speed of motor.And set the time radix (time-base) of automatic reverse winding (auto-reverse) according to the actuating speed of motor.
Begin to heated rollers 340 heating by heating part 330.The temperature of perception heated rollers 340 is with the step S515 of minimum speed CD-ROM drive motor 350.
Next judges but whether the temperature of heated rollers 340 reaches the minimum temperature S520 of press mold.
But do not reached the minimum temperature of press mold by the temperature of temperature sensor 360 eddy-current heating rollers 340, control motor 350 is driven into minimum speed, continues heating for heated rollers 340 by heating part 330.
But reached the minimum temperature of press mold by the temperature of temperature sensor 360 eddy-current heating rollers 340, control part 320 is just controlled motor 350 can compensate the speed operation with the temperature difference of design temperature.
Control part 320 control motors are heated to design temperature for the temperature of heated rollers 340, and the temperature difference of CD-ROM drive motor compensation and design temperature and speedup are to setting speed S525.
Secondly again along with variations in temperature, time radix (time-base) S530 of revisal automatic reverse winding (auto-reverse).
Promptly according to temperature difference, the actuating speed of conversion motor, revisal time radix (time-base) automatically automatically.
If motor drive speed increases thus, T=(T_after-β); If motor drive speed reduces, then T=(T_after+ β).Here T_after refers to for setting speed after changing, the time radix of automatic reverse winding after changing (auto-reverse).
Be that motor drive speed increases, then the time radix reduces β, and motor drive speed reduces, and then the time radix increases β.Here β refers to proportional with motor drive speed and time change.
But the temperature of next heated rollers 340 arrives the minimum temperature of press mold again, and CD-ROM drive motor drops into the plastic packaging film and carries out press mold S535.
Input pickup 380 perception of plastic packaging machine also judge whether film imports S540, if can perceive film, the internal timer S545 that picks up counting is if can not perceive film, then timer is not-time, the temperature of the heated rollers that control is set and the actuating speed S585 of motor.
The plastic packaging film that drops into carries out press mold operation S550 in heated rollers 340 and 370 heating and bonding of bonding roller.(at this moment, Nei Bu timer continues counting.)
Behind the input film, heated rollers 340 is to the film heating in plastic packaging machine, and the heating caudacoria becomes cohesible soft condition, through bonding roller 370 pressings.
Subsequently, output transducer 390 perception of plastic packaging machine and judge whether film exports S555.
After being entered by input pickup 380 perception films, when output transducer 390 perception film output in T second (time-base), then judge it is that the plastic packaging machine operation is normal, timer restarts timing S575, continues normal operation.
After input pickup 380 perception films enter, when not perception film output in T second (time-base) of output transducer 390, then judge card film (JAM) has taken place, timer begins reclocking, stop heating, CD-ROM drive motor 350 contrary rotations drive heated rollers 340 and bonding roller 370 contrary rotation S565.Behind the card membrane removal, heated rollers 340 and bonding roller 370 positive rotation S570.
The contrary contrary rotation of time radix that is rotated in according to the automatic reverse winding (auto-reverse) of S530 step revisal of thermo roll 340 and bonding roller 370.
Judge at last whether design temperature changes S580.
If temperature sensor 360 is measured the design temperature change of heated rollers 340, then the actuating speed of motor is also along with automatic change S525, and the time radix (time-base) of automatic reverse winding (auto-reverse) also changes thereupon simultaneously.
If temperature sensor 360 is measured the not change of design temperature of heated rollers 340, temperature and the motor drive speed of then controlling heated rollers keep within the specific limits.
Embodiment 2.A kind of press mold temperature and speed control unit of plastic packaging machine, as shown in Figure 3.The heating part that this device comprises control part, is connected with control part and is installed in the heated rollers place is connected with temperature sensor, with control part and can drives the motor of heated rollers and bonding roller respectively, is connected with control part and is installed in the input pickup below the fixed part of input port and be connected with control part and be installed in output transducer below the delivery outlet fixed part.The function of control part is that CD-ROM drive motor arrives minimum speed when but the temperature of heated rollers does not have to arrive the minimum temperature of press mold, and continues to heat to heated rollers; When but the temperature of heated rollers reaches the minimum temperature of press mold, continue CD-ROM drive motor, poor with compensation minimum temperature and design temperature; When the temperature of heated rollers reached design temperature, control heating part and motor kept within the specific limits the temperature of heated rollers and motor drive speed.Control part is also connecting can be according to the setting/changing unit of the thickness setting of film or change heated rollers temperature and motor speed.
