Description
Technical field
The utility model relates to a kind of automation control system of cutting machine, the automation control system of specifically a kind of automatic guidance cutting machine home roll and secondary roller rotating speed.
Background technology
At present, the main portion of some cutting machines is made up of a home roll and two secondary rollers, during work, drive by home roll, the paper of the regulatory specifications after cutting is rolled onto respectively on the tube core of two secondary rollers, along with the increase of obbbin radius on the secondary roller, the relative rotation speed of home roll and secondary roller also need change in the scope of setting along with changing the obbbin speed discrepancy that keeps between home roll and the secondary roller.Therefore, have only to keep cutting machine home roll and the corresponding change of secondary roller relative rotation speed, could guarantee in the cutting process that obbbin is smooth and do not rupture along with the increase of obbbin radius.The speed governing system of tradition cutting machine adopts the silicon control Direct Current Governor System, its control element is a breakaway-element, number of elements is many, the trouble point is many, after long-term use, stable equipment operation and precise decreasing, obbbin often ruptures in the cutting process, finally cause yield rate to decline to a great extent, productive costs is increased.
The utility model content
For overcoming the deficiency that above-mentioned prior art exists, technical problem to be solved in the utility model is to provide the automation control system of a kind of automatic guidance cutting machine home roll and secondary roller rotating speed, increase operation stability of equipment by it, improve the yield rate of product.
The technical scheme in the invention for solving the technical problem is: a kind of automation control system of cutting machine, comprise PLC, the home roll frequency converter, with home roll bonded assembly home roll motor, the first secondary roller frequency converter, with the first secondary roller bonded assembly first secondary roller motor, the second secondary roller frequency converter and with the second secondary roller bonded assembly second secondary roller motor, described PLC respectively with the home roll frequency converter, the first secondary roller frequency converter is connected with the second secondary roller frequency converter, described home roll frequency converter is connected with the home roll motor, the described first secondary roller frequency converter is connected with the first secondary roller motor, the described second secondary roller frequency converter is connected with the second secondary roller motor, it is characterized in that, also comprise position transduser, described position transduser is arranged on the roller arm of the roller arm of the first secondary roller or the second secondary roller, and is connected with PLC.
During work, be arranged on the variation that position transduser on the roller arm of the first secondary roller or the second secondary roller detects the obbbin radius, increase along with the obbbin radius, the roller arm slowly opens, the moveable part that drives position transduser outwards stretches, difference according to stretched length, convert the signal of certain limit to, and the signal that obtains passed to PLC, PLC calculates by in-to-in PID control, and control signal sent to the home roll frequency converter, the first secondary roller frequency converter and the second secondary roller frequency converter are controlled corresponding home roll motor respectively, the rotating speed of the first secondary roller motor and the second secondary roller motor.
The beneficial effects of the utility model are, adopt converter technique to combine with PLC, utilize position transduser to detect the variation of obbbin radius, and detected signal sent to PLC, after PLC calculates control signal sent to the home roll frequency converter, the first secondary roller frequency converter and the second secondary roller frequency converter, in order to control corresponding home roll motor respectively, the rotating speed of the first secondary roller motor and the second secondary roller motor, make relative rotation speed corresponding change of cutting machine home roll and the first secondary roller and the second secondary roller along with the increase of obbbin radius, and the speed discrepancy between the home roll and the first auxilliary roller and the second auxilliary roller changes in the scope of setting, increase operation stability of equipment, improved the yield rate of product effectively.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified:
Fig. 1 is a functional block diagram of the present utility model;
Wherein, 1PLC, 2 home roll frequency converters, 3 home roll motors, 4 home rolls, 5 first secondary roller frequency converters, 6 first secondary roller motors, 7 first secondary rollers, 8 second secondary roller frequency converters, 9 second secondary roller motors, 10 second secondary rollers, 11 position transdusers.
The specific embodiment
