Description

High-precision deviation correcting device

Technical Field

The utility model relates to an automatic control technical field especially relates to a high accuracy deviation correcting device.

Background

At present, the reel material is like the film, cloth, paper, the continuous material of equidimension such as foil, in the processing procedure, because the coiled material itself receives the inhomogeneous situation that the coiled material off tracking can often appear of reason such as traction force or equipment own existence deviation, can influence the processing operation's of coiled material quality when the coiled material takes place the off tracking, need shut down sometimes and carry out the manual deviation correction, and then also influenced the process of the processing operation of coiled material, the efficiency of processing has been reduced, need reset so that carry out the action of rectifying next time after current deviation correcting device rectifies, but deviation correcting device can drive the coiled material small amplitude action together after the process that resets, thereby make deviation correcting device need rectify the coiled material many times and just make it accomplish the action of rectifying.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a deviation rectifying device effectual, the position accuracy that rectifies high accuracy.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a high accuracy deviation correcting device, includes the seat of rectifying, rectifies the roller, rectifies sensor, coiled material deflector roll, guide driving piece and locates the drive disk assembly that rectifies of rectifying the roller both sides respectively, rectify the roller surface include the free surface and with the contact surface of coiled material contact, rectify the roller and include the roll body and locate a plurality of pieces of rectifying on its surface along roll body circumference, rectify the piece and set up along roll body length direction, rectify the piece and connect on the roll body and can be relative roll body length direction horizontal slip through reset part, rectify the piece horizontal slip in order to rectify the coiled material that the drive disk assembly drive of rectifying is on the contact surface.

The utility model discloses a theory of operation: the deviation-rectifying sensor detects whether the monitored coiled material deviates from a preset position in the moving process in real time, and if so, a deviation signal is sent to the deviation-rectifying driving part; the deviation rectifying driving part receives the deviation signal, drives the deviation rectifying sheet on the contact surface to slide left and right according to the deviation signal so as to rectify the deviation of the coiled material, and corrects the deviation of the monitored coiled material until the coiled material is recovered to a preset position.

The utility model discloses a control rectification piece in order to realize the action of rectifying a deviation to the coiled material, compare traditional through controlling whole root rectifying roller action, the driving piece that drives whole root rectifying roller action is great, and corresponding, just can have the problem that the drive precision is poor, control rectification piece action now only need less drive power can realize, overcome former deviation correcting device sensitivity poor, can't eliminate the problem of rectifying roller vibration in the rectifying roller operation process; the piece horizontal slip of rectifying that is in on the contact surface through the drive is in order to rectify the coiled material, when rectifying the piece from the contact surface motion to the free surface, rectifying drive assembly removes the drive power to rectifying the piece, and the piece of rectifying resets under the effect of reset part so that use when rectifying next time, can not contact with the coiled material when owing to rectify the piece and be in the free surface, thereby rectify the piece and can not drive the coiled material and move together when the free surface takes place to reset, and then make the utility model discloses when rectifying the coiled material, only can drive the coiled material and move to the skew direction, guaranteed the precision of rectifying the piece when rectifying to the coiled material, and through rectifying the continuous action of piece, can realize rectifying many times, it is effectual to rectify the deviation.
