Method for achieving full-automatic packaging of cold-rolled deformed steel bar production line

Abstract

The invention relates to a method for achieving full-automatic packaging of a cold-rolled deformed steel bar production line. The method is realized on an existing semi-automatic packaging machine andan existing cold-rolled deformed steel bar manual conveying system. A, a length measurement roller is arranged; B, a waiting position proximity switch and a hoisting position proximity switch are arranged on the manual conveying system; C, information exchange communication between the conveying system and the semi-automatic packaging machine is achieved; D, the distance from each wire binding position to the head of a material bale during packing is calculated, Ln=(Lc-Lh-Lt) / (n-1)+Lh, in the formula, Lc is the total length of a bar product to be packaged, Lh is head turn distance, Lt is thetail turn distance, n is the total number of turns, E is the real-time measurement length of the part, passing through the center line of the semi-automatic packaging machine, of the material bale, and the semi-automatic packaging machine runs to conduct wire binding when the length is equal to the length of a certain one in the previous n-1 turns. The method can achieve automatic packaging.

Description

technical field [0001] The invention relates to packaging of cold-rolled wire rods, in particular to a method for fully automatic packaging of a cold-rolled threaded steel bar production line, and belongs to the technical field of cold-rolled wire rods. Background technique [0002] In the hot-rolled wire and bar production line, the disc baler and the bar baler developed on the basis of it have basically achieved localization, the degree of automation is not lower than that of similar foreign products, and the gap in durability and stability is also large. Getting smaller and smaller. However, the packaging process on the domestic cold-rolled rebar bar production line has not been fully automated for the following reasons: [0003] 1) Cold-rolled rebar bar production enterprises are mostly small and medium-sized enterprises. Operators are unwilling to invest too much money in purchasing expensive balers and supporting automation equipment. In their opinion, the ratio of in...

Problems solved by technology

[0003] 1) Cold-rolled rebar bar production enterprises are mostly small and medium-sized enterprises. Operators are unwilling to invest too much money to buy expensive balers and supporting automation equipment. In their opinion, the ratio of investment and income is not cost-effective.

[0004] 2) The speed of the existing cold-rolled rebar bar production line is low, and the demand for full automation of the packaging process is not so strong

[0005] 3) The baler supplier can only provide the main machine of the baler, and the supporting feeding and conveying system often requires the enterprise to solve it by itself, and these small and medium-sized enterprises do not have the technical ability to design an automatic conveying and feeding system that is matched with the baler, and cannot realize the packaging. fully automated

The advantage of the semi-automatic packaging method is that the equipment investment is small, the electronic control system is relatively simple, and the entire packaging operation can be completed on an operation box, the labor intensity is not large, and it can adapt to a higher production speed; the disadvantage is that it is still inseparable from the operation. personnel, and the packing speed is relatively limited, which does not adapt to the development trend of the continuous speed-up of the rebar bar production line
