Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, two servomotor translation systems that a kind of precision is high, response is fast, the rolling quality is high are provided.
In order to achieve the above object, the present invention realizes through following technical scheme:
The present invention provides a kind of pair of servomotor translation system; Comprise servomotor, high precision planetary reducer, the ball screw of micron order precision, motion controller, servo-driver; Described two servo-drivers connect through internal bus interface; Described motion controller has constituted the topological structure between controller and the driver jointly with the internal bus interface between the servo-driver; Each servo-driver can drive two servomotors simultaneously; After the ball screw of servomotor described high precision planetary reducer of process and micron order precision links to each other, constituted the outside and inboard sliding turnover mechanism jointly, system also comprises idle condition, on load operation state, the idling of machine.
What the of the present invention pair of servomotor translation system adopted is the method for location positioning, utilizes the synchronizing function of Siemens's motion controller between two motors, ensure two motors to swing in the walking amount of showing and moving back slowly be duplicate.
In the machine idle condition of the present invention, it is to press according to operating personnel to swing in the button of showing and carry out action that the swinging in of machine shown operation, ensures the synchronizing function of two motors.
At the extreme position of machine run at machinery, programmed logic and external travel switch are provided with safeguard protection.
In the machine on load operation state of the present invention, along with the increase of film coil diameter, the rolling arm will be retreated continuously, carries out positioning function.
To be program constantly refresh the position location of diameter value, motor through CPU to positioning function of the present invention, realizes that continuity retreats.
Continuity of the present invention is retreated the stability that can keep on film volume and the pressure roller physical construction, guarantees the reliable and stable of rolling quality.
Machine no-load operation state of the present invention, two servomotor translation systems are to be stationary state.
Beneficial effect of the present invention comprises at least:
1. can reduce pollution;
2. the precision of servomotor, planetary reducer and the ball screw of system's employing all reaches micron order, and system's cumulative errors are minimum, and servo response is exceedingly fast, and can satisfy the stability of cutting at a high speed greatly, has improved the precision and the response of system;
3. through the high precision ball screw mandrel translation system of two driven by servomotor, can optimize the rolling quality, satisfy the requirement of cutting of high-speed, high precision.

Embodiment
Below in conjunction with Figure of description technical scheme of the present invention is described further:
A kind of pair of servomotor translation system comprises that ball screw, Siemens's motion controller, the servo-driver of Siemens's servomotor, high precision planetary reducer, micron order precision formed two servomotor translation systems.As shown in Figure 1, described two servo-drivers are to connect through internal bus interface, and Siemens's motion controller has constituted the topological structure between controller and the driver jointly with the internal bus interface between the servo-driver.Each servo-driver can drive two servomotors simultaneously; After the ball screw of servomotor process high precision planetary reducer and micron order precision links to each other; Constituted the outside and inboard sliding turnover mechanism jointly, system also comprises idle condition, on load operation state, the idling of machine.
That servo-driver of the present invention adopts is SINAMICS-S120; That Siemens's motion controller adopts is the SIMOTIOND425/D435/D445 of Siemens Company; What servomotor adopted is Siemens 1FK7 servomotor; What the high precision planetary reducer adopted is APEX high precision planetary reducer, and what the ball screw of micron order precision adopted is the FFZD series of Nanjing technology.
What two servomotor translation systems adopted is the method for location positioning, utilizes the synchronizing function of Siemens's motion controller between two motors, ensure two motors to swing in the walking amount of showing and moving back slowly be duplicate.Two servomotor translation system control flow charts are as shown in Figure 2; Swinging under the machine idle condition shown operation; Be to press according to operating personnel to swing in the button of showing and carry out action, at this moment just ensure the synchronizing function of two motors, do not carry out positioning function; But at the extreme position of machinery, programmed logic and external travel switch all are provided with safeguard protection.When machine in the on load operation process; Along with the increase of film coil diameter, need to guarantee retreating continuously of rolling arm, what carried out this moment is positioning function; Program refreshes diameter value through the scan period of CPU Millisecond; According to the increment of diameter value, constantly refresh the position location of motor, thereby the realization continuity is retreated.Continuity is retreated the relative position on the physical constructions such as can keeping film volume and pressure roller, thereby guarantees the reliable and stable of rolling quality.During the machine no-load, translation system is to be stationary state.
Traditional rolling upset and translation mechanism, employing be hydraulic control system.The translation system that servomotor adds ball-screw can reduce pollution by comparison: in most industries of film, all be the field that is applied to high cleanliness such as food and medicine, hydraulic oil exists and pollutes, so and be not suitable for using; Improved the precision and the response of system: the precision of servomotor, planetary reducer and ball screw all reaches micron order, and system's cumulative errors are minimum, and servo response is exceedingly fast, and can satisfy the stability of cutting at a high speed greatly; Improve the rolling quality: there is greater impact in the hydraulic valve action, and is bigger to film volume quality influence.
The problems that the hydraulic pressure translation mechanism exists can solve through the high precision ball screw mandrel translation system of two driven by servomotor, reach and optimize the rolling quality, satisfy the requirement of cutting of high-speed, high precision.
It should be noted that; What more than enumerate only is a kind of specific embodiment of the present invention; Should be pointed out that to those skilled in the art, do not breaking away under the core technology characteristic prerequisite of the present invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
