Spherical label continuous bidding device applied to coal conveying belt coal quality identification

Abstract

The invention provides a spherical label continuous bidding device applied to coal conveying belt coal quality identification. The spherical label continuous bidding device comprises at least two label pipes, a rotary disc, an index plate, a fixed disc, a counter, a ball ejecting electromagnetic valve, a ball blocking electromagnetic valve, a label reader, a bidding material channel, a recycling bin, a judging part and a control part, wherein the label pipes are arranged at intervals in the circumferential direction of the rotary disc in a penetrating mode; the index plate drives the rotary disc to rotate by a preset angle; the fixed disc is arranged below the rotary disc, ball falling openings corresponding to the outlet ends of the label pipes are formed in the peripheral area, and spherical labels which rotate to the positions along with the rotary disc can fall off; the counter is arranged towards the ball falling openings; the ball ejecting electromagnetic valve is arranged besidethe rotary disc, and an ejector pin faces an operation opening of the label pipe located above the ball falling openings; the ball blocking electromagnetic valve is arranged beside the fixed disc, and an ejector pin faces the bottoms of the ball falling openings; the label reader moves to the position under the ball falling openings when in a label reading state; the bidding material channel moves to the position under the ball falling openings when in a bidding state; the recycling bin moves to the position under the ball falling openings when in a recycling state; and the judging part judges whether the label information is correct or not.

Description

technical field [0001] The invention belongs to the field of intelligent equipment for power plants, and in particular relates to a spherical label continuous bidding device applied to coal quality identification in coal conveying belts. Background technique [0002] The Internet of Things refers to the real-time collection of any objects or processes that need to be monitored, connected, and interacted through various devices and technologies such as information sensors, radio frequency identification technology, global positioning systems, infrared sensors, and laser scanners. The network access realizes the ubiquitous connection between things and things, things and people, and realizes the intelligent perception, identification and management of objects and processes. With the further advancement of my country's economic restructuring and transformation and upgrading, the Internet of Things technology based on radio frequency identification (RFID) has been widely used in...
