Abstract

A double-row roller position detection device belongs to the application field of automatic intelligent control technology. The device installs laser rangefinder sensor on the sensor support, and laser rangefinder sensor is connected with analog input module, and analog input module is connected with programmable controller. The laser ranging sensors detect the distance between the end parts of the rollers on the roller frames on the two sides, the programmable controller calculates the offset of the rollers according to the detected distance, then the offset of the rollers is transmitted to the programmable controller of the half gantry crane, and the position of the rollers is accurately corrected according to the offset of the rollers when the half gantry crane is hoisted, so that the rollers are accurately positioned when being loaded to the grinding machine. The device conveys the roll offset to half gantry crane controller, and half gantry crane carries out the accuracy correction to the roll position according to the offset when hoist and mount roll, satisfies the roll and loads to the accurate positioning requirement of grinding machine, can detect both sides roll position simultaneously, effectively reduces mechanical injury, improves the intelligent level of mill.

Description

Double-row roller position detection device

Technical Field

The utility model belongs to automatic intelligent control technique is used, detects the roll tip distance row on the roll stand of both sides through laser range finding sensor, and programmable controller calculates the roll offset according to the distance that detects, conveys half gantry crane programmable controller with the roll offset again, and half gantry crane carries out the accuracy correction to the roll position according to the roll offset when hoist and mount, realizes that the roll loads the accurate positioning to the grinding machine.

Background

A crown block is manually operated between the cold rolling grinding rollers to place the rollers on the fixed roller frame, and then the rollers are automatically hoisted to the grinding machine by a half gantry crane which can be accurately positioned by servo control. Because the self inertia of the crown block is large and the uncertainty of manual operation causes the control precision of the crown block controlled by the frequency converter to be low, the condition that the deviation between the roller center and the roller frame center is overlarge when the crown block puts the roller is frequently generated. The traditional solution is to manually operate a mechanical device to push the roll end to the proper position locking device when the overhead travelling crane lowering roll is about to contact the roll stand, and then the roll falls completely on the roll stand. The mechanical device has simple structure and higher positioning precision. The defect is that the labor intensity is high, the risk of mechanical striking of an operator is high, the positioning precision can be gradually reduced along with the mechanical abrasion caused by the use of the device, and the later maintenance cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a reduce artifical intensity of labour, reduce mechanical striking risk, improve positioning accuracy simultaneously, improve the intelligent level of production efficiency and mill, provide a double roll position detecting system.

The utility model mainly relates to the technical content is the detection technology of the end position of the roller and the application of industrial PLC (programmable Logic controller) knowledge.

A double-row roller position detection device comprises a laser ranging sensor 1, a sensor bracket 2, an analog input module 3 and a programmable controller 4; laser rangefinder sensor 1 installs on sensor support 2, and laser rangefinder sensor 1 is connected with analog input module 3, and analog input module 3 is connected with programmable controller 4.

The laser ranging sensor 1 mounted on the sensor holder 2 transmits the detected position signal to the programmable controller 4 through the analog input module 3.

The laser ranging sensor 1 is aligned to the end position of the roller to realize the detection of the end position of the roller; and the programmable controller is connected with the half-door hanger controller so as to transmit the offset of the roller to the half-door hanger controller.

The end position of the roller is detected by a laser ranging sensor which is the main detection element of the system, and the accuracy of the laser sensor directly influences the detection of the end position of the roller. The industrial PLC is a core control component of the system, the roll offset is calculated by receiving signals of the laser ranging sensor, and the half gantry crane achieves accurate positioning of loading of the roll to the grinding machine according to the roll offset detected by the double-row roll position detection system through the servo control system.

The device conveys the roll offset to half gantry crane controller, and half gantry crane carries out the accuracy correction to the roll position according to the offset when hoist and mount roll, satisfies the roll and loads to the accurate positioning requirement of grinding machine, can detect both sides roll position simultaneously, effectively reduces mechanical injury, improves the intelligent level of mill.
