Device and method for feeding and discharging of LNG cylinders in processing area

Abstract

The invention relates to a device and method for feeding and discharging of LNG cylinders in a processing area. A roller type conveying line for feeding and a roller type conveying line for discharging are arranged on the two sides of a processing station in parallel. A claw type jacking translation mechanism is arranged between the roller type conveying line for feeding and the roller type conveying line for discharging and located at the processing station. The roller type conveying line for feeding and the roller type conveying line for discharging are of the same structure and each comprise an installation frame and a row of conveying rollers installed on the installation frame. The structural form of each installation frame is one of the following two types that in the first type, a channel is reserved in the installation frame, and in the second type, no channel is arranged on the installation frame, and the feeding position of the roller type conveying line for feeding and the discharging position of the roller type conveying line for discharging are each provided with an LNG cylinder jacking mechanism. The device is wide in application range, simple in structure, convenient to operate and capable of effectively reducing the occupied area of production lines, and the purposes that workpieces on one production line can be rapidly transferred to another production line, and the production efficiency is improved are achieved.

Description

technical field [0001] The invention relates to LNG gas cylinder processing equipment, in particular to a device and method for feeding and discharging LNG gas cylinders in a processing area. Background technique [0002] As a pressure vessel for storage of cryogenic liquids, LNG cryogenic insulating gas cylinders have been widely used at home and abroad. LNG gas cylinders are used as the core equipment of raw material supply systems in many industries. It has the advantages of light weight, large filling capacity, pure gas and liquid, convenient transportation and loading and unloading, and safety and reliability. [0003] At present, there are many automatic production lines for LNG cylinders put into use in China. After a detailed investigation of the solutions for the automatic production lines of LNG cylinders disclosed in the market, it is found that the general rule is that the processing equipment often needs a long time. The transfer line usually adopts a unified p...

Problems solved by technology

[0003] At present, there are many automatic production lines for LNG cylinders put into use in China. After a detailed investigation of the solutions for the automatic production lines of LNG cylinders disclosed in the market, it is found that the general rule is that a long time is often required between processing equipment. The transfer line usually adopts a unified plane and multi-row parallel layout structure. There are only 1 or 2 processing equipment in a single line of production line, and the workpiece enters the processing equipment line from the main conveying line. The processing area has a long turnaround time period and scattered equipment structure, which occupies a large area, greatly reducing production efficiency and profit output

There are some equipment used for pipe transportation in the prior art, such as the patent with the authorized notification number CN106626153B, which discloses a support transfer platform for pipes, which is suitable for the transmission of long pipes, but it is not suitable for LNG gas. Transfer of bottles between processing stations and infeed and outfeed conveyor lines
