Problems solved by technology

In this method, the height alignment and width alignment are performed separately. The height alignment requires a lifting cylinder with a displacement sensor, which is relatively expensive, and the outer diameter of the steel coil needs to be input in advance, and there is a deviation between the input value and the actual value, so alignment low precision
The width centering sensor is placed on the ground, and the sensor is easily damaged

Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] refer to figure 1 and figure 2 , a swing arm type automatic winding centering device, including a pair of swing arms 1, the swing arms 1 are connected together through the shaft 2, the bearing seats 3 supporting the shaft 2 are fixed on the bracket 6, and the middle of the shaft 2 is fixed The swing rod 4 which forms 90° with the swing arm 1 is connected with the swing cylinder 5, and the swing cylinder 5 pushes the swing rod 4 to rotate 90°, drives the shaft 2 to rotate, thereby drives the swing arm 1 to swing up and down.

[0017] refer to figure 1 and image 3 , the front end of the swing arm 1 is a T-shaped structure, and four groups of opposite-beam photoelectric switches are symmetrically arranged in the vertical direction centered on the T-shaped center. The distance between the second group of photoelectric switches 8 and the third group of photoel...

Abstract

The invention discloses a swing-arm-type automatic winding and centering device which comprises a pair of swing arms, wherein the swing arms are linked together through a shaft; bearing seats of two support shafts are fixed on a support; a swing rod which forms an angle being 90 degrees with the swing arms is fixed in the middle of the shaft; a swing oil cylinder pushes the swing rod to rotate so as to drive the shafts to rotate, so that the swing arms are driven to swing up and fall off; four groups of correlation-type photoelectric switches and a group of laser ranging sensors are installed on the swing arms, and the height centering and width centering of steel coil winding can be realized at the same time, so that the automatic winding function of steel coils is realized. The swing-arm-type automatic winding and centering device has the characteristics of simple structure, low cost, high accuracy, high reliability and the like.

Description

technical field [0001] The invention relates to the field of an automatic coiling device for a steel coil coiling trolley in a production line of a cold rolling mill, in particular to a swing arm type automatic coiling centering device. Background technique [0002] The automatic coiling device is widely used in the reversing cold rolling unit and the production line of the full continuous cold rolling unit. It is a manifestation of the automation level of the unit, which can reduce labor costs and shorten the coiling time, so it is widely used. [0003] The realization of automatic winding is achieved by the height center of the steel coil being equal to the height center of the reel, and the coincidence of the width center of the steel coil with the center of the unit, that is to realize the height alignment and width alignment of the steel coil. The traditional automatic coil height centering measures the distance from the outer diameter of the steel coil to the sensor by...
