Automatic overturning and conveying device and method for cartridge cases

Abstract

The invention belongs to the technical field of bullet assembling, and particularly relates to an automatic overturning and conveying device and method for cartridge cases.The cartridge cases are pushed into an inlet guide hanging plate in an inverted hanging mode after the opening painting procedure is completed on associated equipment, a radial feeding air cylinder stretches out, a front push plate is inserted into the gap between the cartridge cases, and a push-in air cylinder stretches out before overturning. The front push plate pushes the cartridge cases into the overturning hanging plate, a servo motor drives the rotating shaft to turn over through a synchronous belt, the rotating shaft rotates by 90 degrees every beat, the cartridge cases are turned over by 180 degrees after being rotated twice, the push-out air cylinder stretches out after turning over, the rear push plate pushes the cartridge cases onto an outlet guide plate, and the cartridge cases are driven by the conveying chain to enter a drying conveying line. According to the device and method, bullet assembly production equipment is organically connected into an automatic production line, automatic continuous operation of bullet assembly production is achieved, and the production efficiency is effectively improved. Meanwhile, the cartridge cases are hung upside down by utilizing a cartridge case shifting groove, and the opening part of each cartridge case is not in contact with equipment in the overturning process, so that the pollution of paint liquid to the cartridge cases and the equipment is avoided.

Description

technical field [0001] The invention belongs to the technical field of bullet assembly for weapons and equipment, and in particular relates to a device for automatically turning over and conveying bullet casings, and a method for automatically turning and conveying bullet casings based on the device. Background technique [0002] During the bullet assembly process, in order to ensure the stable performance of the propellant and improve the shooting accuracy, it is required to coat the inner wall of the shell with 5-8mm wide bitumen paint for sealing. The painting process is generally carried out by hanging the mouth downward. To facilitate the drying of the paint liquid and the subsequent charging, it is necessary to turn the cartridge case over 180° so that the mouth is upright and enters the drying transmission line. The traditional production method puts the painted shells directly into the product turnover box, and after 12 hours of natural drying, they are placed on the...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the traditional production method of painting shell casings is inefficient and the shell casings are often polluted by hanging paint liquid; based on this, the present invention provides a kind of automatic flipping and conveying device for bullet casings, and the automatic flipping and conveying of bullet casings based on the device method, the purpose is to improve work efficiency, and avoid the contamination of the cartridge case by the hanging paint liquid, and save the workload of subsequent appearance cleaning
