Abstract
The utility model relates to a plastic machinery, in particular to a control system of a rolling machine, which aims at providing a plastic rolling machine electric control system which has reliable control and rapid and good rolling. The plastic rolling machine electric control system comprises a touch screen, a PLC module, a frequency converter, a motor, an angle instrument and an approaching switch; the touch screen is connected with the PLC module through a RS-232 communication, and the PLC module is connected with the frequency converter in double directions, and the motor is connected with the frequency converter in double directions, and the angle instrument is connected with the PLC module, and the approaching switch is connected with the PLC module. The plastic rolling machine electric control system overcomes the problems of the prior art that the coiled edge is not tidy, is non-uniform and is too tight to be crinkled during the rolling process; at the same time, the rolling speed is greatly improved and the yield is increased.
Description
Technical field
The utility model relates to plastics machinery, relates to the wherein control system of winder especially.
Background technology
We adopt Torque Control substantially at homemade rolling, and the relative simple cost with electric part of machinery is also done low.And external winder adopts the AC servo motor cost quite high substantially, as the about Renminbi of German Kang Fu winder more than 4,000,000; The about Renminbi of Japanese fuji winder is more than 2,000,000.
Winder originally mainly adopts torque motor to carry out rolling, and main defective and the deficiency that exists is that the rolling limit is irregular, and degree of tightness differs, or the too tight a series of problems such as wrinkling of product.Adopt tension control and tapering to control to overcome by the electric part transformation and deposited defective and deficiency.
The utility model content
The purpose of this utility model provides a kind of control reliable, the faster and better plastics winder electric-control system of rolling.
The technical scheme that realizes the utility model purpose is as follows:
A kind of plastics winder electric-control system, said system comprise touch-screen, PLC module, frequency converter, motor, position, angle instrument and near switch; Touch-screen and PLC module adopt RS-232 to communicate to connect, and the PLC module is connected with frequency converter is two-way, and motor is connected with frequency converter is two-way, and position, angle instrument is connected with the PLC module, is connected with the PLC module near switch.
The model of above-mentioned touch-screen is Eview-MT510, and PLC module model is FX2N-128, and the model of frequency converter is MD330, is PRL18-5DN near the model of switch.
The utility model control system has increased position, the angle instrument of following the tracks of material volume tension and has controlled to carry out tension on the basis of original Torque Control, adds near material coil diameter on the switch monitoring winder to change to carry out the motor speed adjustment.It is irregular that above measure has overcome crimping, and degree of tightness differs, and some problems in rolling such as too tight wrinkling grade have improved rolling speed greatly simultaneously and improved output.Because this control system adopts touch screen human-computer interface, greatly enrich, made things convenient for control operation in addition, both improved production efficiency and also reduced the cost of labor of producing.
Description of drawings
Fig. 1 is the utility model control block diagram.
Embodiment
See Fig. 1, the utility model electric-control system comprises touch-screen, PLC module, frequency converter, motor, position, angle instrument and near switch; Touch-screen and PLC module adopt RS-232 to communicate to connect, and the PLC module is connected with frequency converter is two-way, and motor is connected with frequency converter is two-way, and position, angle instrument is connected with the PLC module, is connected with the PLC module near switch.The model of above-mentioned touch-screen is Eview-MT510, and PLC module model is FX2N-128, and the model of frequency converter is MD330, is PRL18-5DN near the model of switch.
The PLC module is the native system Central Control Module, and the operation of being responsible for receiving from touch-screen requires and send corresponding execution command.Comprise D/A converting unit and A/D converting unit in the PLC module, the digital signal that PLC sends sends to frequency converter through converting simulating signal to, carries out Torque Control, promptly allows motor torque constant as far as possible, makes the rolling stable working.In addition, be used for monitoring the variation of material coil diameter on the winder, and a corresponding diameter signal is sent among the PLC, send by the PLC module again and adjust signal and give frequency converter near switch.When material coil diameter was less on the winder, motor rotated with fast speed.When coil diameter becomes big, the PLC module sends the instruction that slows down motor speed, and frequency converter makes motor speed slack-off by reducing the out-put supply frequency, and the photoelectric encoder that is installed in simultaneously on the machine shaft is being monitored motor speed constantly, and feed back to frequency converter, make motor keep stable rotating speed as early as possible.
Position, above-mentioned angle instrument is installed on the roller of winder, and the tension that is used for following the tracks of material on the roller changes.When the variation of material tension causes that roller relatively rotates, position, the angle instrument that is installed in roller can be transformed into this change in location electric signal and send to the PLC module, through the conversion of A/D converting unit, the PLC module can be sent corresponding instruction and give frequency converter, adjusts rotating speed of motor.When the material tension becomes big, need the PLC module to send the instruction that slows down motor speed, opposite then need the PLC module to send to accelerate the instruction of motor speed.Same photoelectric encoder can make motor speed remain to as soon as possible on the rotating speed of instruction setting.
Calculate the turnout of material for convenience and realize automatic cutter control, the utility model also is provided with meter counter, after configuring meter numerical value, when the outflow material reaches this setting value, meter counter sends signal can for the PLC module, the PLC module can be suspended material rolling work and carry out cutter and cut, and also can be other operations that need.
Claims (2)
1, a kind of plastics winder electric-control system is characterized in that: said system comprises touch-screen, PLC module, frequency converter, motor, position, angle instrument and near switch; Touch-screen and PLC module adopt RS-232 to communicate to connect, and the PLC module is connected with frequency converter is two-way, and motor is connected with frequency converter is two-way, and position, angle instrument is connected with the PLC module, is connected with the PLC module near switch.
2, plastics winder electric-control system according to claim 1, it is characterized in that: the model of above-mentioned touch-screen is Eview-MT510, and PLC module model is FX2N-128, and the model of frequency converter is MD330, is PRL18-5DN near the model of switch.
