Novel steel cylinder steel stamp number marking device and method

Abstract

The invention relates to the technical field of steel cylinder marking machines, in particular to a novel steel cylinder steel stamp number marking device. The marking device comprises a fed cylinderconveying line, a steel cylinder rotating mechanism and a marking machine, wherein the steel cylinder rotating mechanism is arranged at the position, close to a fed cylinder, of the fed cylinder conveying line, the steel cylinder rotating mechanism comprises a support, a driving wheel arranged on one side of the support and driven through a motor, and a driven wheel arranged on the other side of the support, the marking machine is installed on the support, a pressing air cylinder is arranged at the top of the support, and a pressing head is arranged on a piston rod of the pressing air cylinder. According to the novel steel cylinder steel stamp number marking device, steel cylinder numbers are not pre-impressed on a steel plate of a steel cylinder protective cover, while in the movement process of the conveying line, steel cylinder number marks are formed on the steel cylinder protective cover in a etched or struck mode by means of laser or other methods when the steel cylinder is closeto a detection machine, meanwhile, through the method through which steel cylinder number information is directly transmitted to a computer, the steel cylinder steel stamp numbers are prevented fromrusting and being polluted in the heat treatment and transferring processes, the errors in the processes of photographing, computer recognition and the like are avoided, and the requirements of rapidly and accurately recording the steel cylinder numbers are met.

Description

technical field [0001] The invention relates to the technical field of steel cylinder marking machines, in particular to a novel steel cylinder stamp number marking device and method. Background technique [0002] TSG R0006-2014 "Gas Cylinder Safety Technology Supervision Regulations" stipulates that the hydrostatic test of gas cylinders must "automatically record the bottle number, test time and test results in real time". Before the present invention, the marking and recording of the steel cylinder stamp number used a machine to print and press on the steel cylinder shield steel plate, and manually observed and recorded manually. The detection equipment produced by our company in the early days used the method of manually inputting PLC records on the touch screen, and later used By rotating the code reader to take pictures and then machine (computer) identification. [0003] The applicant found the following disadvantages during use: [0004] 1) The method of manual obse...

AI Technical Summary

Problems solved by technology

[0004] 1) The method of manual observation and manual recording does not meet the requirements of the automatic detection line

The automatic detection line can automatically record and store the detection data in the hydrostatic test process and store them in the database. Only the cylinder number cannot be automatically recorded and stored, resulting in the detection data not corresponding to the cylinder number, so it is impossible to realize the cylinder number Query the test results

[0005] 2) Although the method of manually inputting the cylinder number into the PLC on the touch screen can realize the simultaneous storage of the cylinder number and test data, the speed of manual input cannot keep up with the detection speed. Under normal circumstances, the detection line detects a cylinder within 10 seconds , it is very tiring for people to keep up with this speed, and it will also produce a large error rate

[0006] (3) Although the rapid identification and input of the steel cylinder number is realized through the method of taking a photo of the rotary code reader and then machine (computer) identification, it also puts forward high requirements for the clarity of the steel cylinder code printed on the steel cylinder shield. Due to the different materials of steel cylinder shields in steel cylinder manufacturers, different printing depths of steel codes, pollution and corrosion of steel cylinders in the heat treatment process and subsequent transfer process, the recognition rate of steel cylinder numbers has been greatly affected and cannot meet the requirements. Requirements for real-time automatic recording and continuous testing of the production plant
