Multi-sensor counting device and counting method for detecting concave plate-shaped objects

Abstract

The invention discloses a multi-sensor counting device for detecting recessed plate-shaped member and a counting method thereof. The multi-sensor counting device comprises a processing module, an interface module and a plurality of sensors. The plurality of sensors are equidistantly arranged below a plate-shaped member conveying device and detect whether the plate-shaped member exists above the sensors. The processing module successively reads state values of all sensors and records corresponding sensor numbers every spacing time deltat, and constructing a 1-area data logarithm set. Then the processing module performs overlapping determining on the 1-areas which are detected in two adjacent times of the spacing time deltat and stores a counting value. The steps are repeated until counting of all plate-shaped members is finished. The multi-sensor counting device is suitable for the counting operation for all convex plate-shaped members, recessed plate-shaped members and combination of the convex plate-shaped members and the recessed plate-shaped members, thereby preventing counting omission and repeated counting in an existing counting device and counting method, and greatly improving counting precision. Furthermore the multi-sensor counting device has advantages of low cost, low use environment requirement and wide application range.

Description

technical field [0001] The invention relates to a counting device and a counting method, in particular to a multi-sensor counting device and a counting method for detecting concave plate-like objects. Background technique [0002] At present, in the industrial production process, it is often necessary to count and count the concave plates. For example, in the glass processing process, it is necessary to count and count the glass on the conveying roller to achieve precise management of the production process. [0003] The existing counting and statistical methods for concave plate-shaped objects mainly include the following: [0004] 1. Manual counting. [0005] The traditional manual counting method greatly consumes human resources, increases the labor intensity of the staff, and has the defect of inaccurate counting. [0006] 2. Single sensor counts independently. [0007] When a single sensor is used for independent counting, since each sensor is in a fixed position and...

Problems solved by technology

[0007] When a single sensor is used for independent counting, since each sensor is in a fixed position and always detects a row of glass in the same moving direction independently, when a large piece of glass covering two or more rows passes by, it will be detected by multiple sensors. The sensors detect it at the same time, causing repeated counting; when a small piece of glass with a coverage area smaller than the gap between the two sensors passes by, it may pass between the two sensors but cannot be detected by any sensor, directly resulting in a missing count. ; Therefore, single-sensor independent counting cannot meet the multi-station counting requirements of different glass sizes in the actual production process, and the counting accuracy is very low, which cannot meet the actual use needs

[0008] The patent "a multi-sensor counting device and counting method" with the application date of January 22, 2013 and the application number 201310022573.X discloses a multi-sensor counting device and a counting method, which can detect different Regular arrangement for accurate counting, but in the case of concave glass, there will be under-counting or over-counting phenomenon, resulting in inaccurate counting, which cannot meet the counting requirements of fully concave or convex-concave mixed glass
