Raw tobacco gunny bag unloading, collecting and storing device based on machine vision

Abstract

The invention discloses a raw tobacco gunny bag unloading, collecting and storing device based on machine vision. The raw tobacco gunny bag unloading, collecting and storing device comprises a feedingconveying line and an automatic stacker crane arranged on the feeding conveying line, a rotary conveying line closely attached to the feeding conveying line is arranged at one end of the feeding conveying line, the rotary conveying line is U-shaped, a support frame is arranged between the horizontal ends of the rotary conveying line, and a cross beam is arranged on the support frame in a slidingmanner; and a visual positioning camera is arranged at the middle point of the cross beam, sliding frames capable of sliding along the central axis of the cross beam are arranged on the two sides of the visual positioning camera, clamping assemblies capable of moving up and down to clamp gunny bags are arranged on the sliding frames, and a bearing conveying line communicating with the rotary conveying line is arranged below the clamping assemblies. The beneficial effects of the raw tobacco gunny bag unloading, collecting and storing device is mainly reflected in that the quality and weight detection of the raw tobacco gunny bags one by one is achieved, the mastering and monitoring degree of the raw tobacco quality condition is greatly improved, and reliable data support is provided for tobacco storage safety, subsequent processing technology quality control and production scheduling arrangement.

Description

technical field [0001] The invention relates to storage and framing equipment in the tobacco leaf industry, in particular to a machine vision-based unloading and storage device for raw tobacco sacks. Background technique [0002] At present, the warehousing of raw tobacco in tobacco leaf redrying enterprises is divided into the traditional and conservative manual unloading, sampling and testing methods and the automatic unloading, testing and sorting system of raw tobacco packs. [0003] The schemes and disadvantages adopted in each link of manual unloading and sampling inspection: [0004] Manual unloading method: it takes a lot of manpower (about 6 to 10 people are needed to unload a car), because it is laborious to carry a pack of about 50KG cigarette packs, the unloading workers usually take the cigarette packs directly from a height of 4 to 5 meters. The trucks were thrown to the ground, and then carried away by the workers under the truck. This method directly caused ...

AI Technical Summary

Problems solved by technology

The existing problems are: chemical data detection takes a long time, the detection process requires the use of toxic chemical reagents, the representativeness of sampling is not strong, the hardware equipment configuration is lacking, the management methods are relatively backward, and the level of informatization is not high

Disadvantages: poor sampling representativeness, 30% sampling rate cannot represent the real weight of the whole car of cigarette packs, large weight error introduced by weighing with a trolley, and slow weighing speed and low efficiency
