A method and device for counting and bundling bar rolled pieces

Abstract

The invention relates to a bar rolled piece counting and bundle separating method and device. A counter arranged at the tail end of a cooling bed is used for counting the number of aligned bar rolled pieces passing through the tail end of the cooling bed, a first counting value is obtained, and when the first counting value reaches a first threshold value, the counted bar rolled pieces conforming to the first threshold value are determined as a set; the bar rolled pieces determined as the set are conveyed to a shearing line to be sheared; the sheared bar rolled piece sets are conveyed to a chain transfer part; the number of the bar rolled piece sets passing through the tail end of the chain transfer part is counted through a counter arranged at the tail end of the chain transfer part, a second counting value is obtained, and when the second counting value reaches a second threshold value, it is determined that the bundling counting of the bar rolled pieces is over; all the bar rolled piece sets obtained after the bundling counting is completed are transferred and conveyed out; the transferred and conveyed-out bar rolled piece sets are bundled, wherein the product of the first counting value and the second counting value is the number of the bar rolled pieces corresponding to bar rolled pieces with the preset weight. The bar rolled piece counting and bundle separating method and device can improve the accuracy of counting and bundle separating of the rolled pieces.

Description

Technical field [0001] The present disclosure relates to the field of metallurgical machinery, and in particular to a method and device for counting and bundling bar rolling stock. Background technique [0002] In the traditional technology, the bar rolling pieces cut to length on the transmission line need to be counted manually, which is often inefficient. [0003] In order to improve the counting efficiency of rolling stock, the imaging principle can be used for counting in the prior art. Specifically, light is used to irradiate the end surface of the sheared rolled sheet bundle and counted using reflected light. However, this method has very high requirements on the shearing end face of the rolled piece and the conveying position and speed of the rolled piece. Due to the fixed length of the bar and the relatively small diameter, the rolled pieces are prone to bending and lamination during the conveying process, resulting in insufficiently clear imaging of the end surface of t...

AI Technical Summary

Problems solved by technology

However, this method has high requirements on the shear end face of the rolled piece and the conveying position and speed of the rolled piece.

Due to the long length and relatively small diameter of the bar, the rolled piece is prone to bending and stacking during the conveying process, resulting in the image of the end face of the rolled piece bundle is not clear enough, and the final counting and bundling is not accurate enough

[0004] It can be seen that under the existing counting and bundling method of bar rolled pieces, there are still defects of inaccurate bundling
