Description

A conveyor express automatic counting device

technical field

The invention relates to the field of counting express pieces, in particular to an automatic counting device for express pieces of a conveyor.

Background technique

With the rapid development of express delivery and e-commerce, a large number of express shipments are generally transported by conveyors in the warehouse, and can only enter the delivery and distribution link after sorting. With the application of sorting information equipment, operators need to know the number of express items entering the sorting line in real time. These data are very beneficial to the evaluation and adjustment of operation efficiency. Therefore, the express counting efficiency is very important for the operator to improve sorting efficiency, reduce costs, and enhance competitiveness.

At present, the traditional express counting is mainly realized by manual counting, barcode automatic equipment, and visual automatic equipment. Manual counting is to use manpower to count the number of express items entering the conveyor. This method requires a large amount of manpower and has large errors. Barcode automatic equipment is to install a gantry with a barcode reader on the conveyor to automatically identify the barcode on the express, and judge the number of expresses passing through the gantry by the number of barcodes. Manual intervention is required to keep the barcode of the express up. for the device to scan. Vision automatic equipment is to install a gantry with visual recognition equipment on the conveyor. After taking pictures of the express shipments on the conveyor, the software will identify the number of express shipments and output the number of express shipments. This method performs software recognition based on visual images. If the image quality is not good or the express shipments are placed too close together, there will be data error problems, and manual intervention is often required in actual use.

Both barcode automatic equipment and visual automatic equipment have limitations such as high installation and use costs and high environmental requirements (ground, space, lighting, etc.). From a technical point of view, whether it is barcode recognition or visual recognition, there is a problem of recognition depth of field. A single device generally achieves a depth of field of 0-60cm at most, and the cost is very high, and it is impossible to count some high-height express items. The barcode recognition technology with a wide range of depth of field is basically monopolized by foreign countries, which leads to high cost of barcode automatic equipment counting, which seriously restricts its application in the industry.

To sum up, the e-commerce and express logistics industries are in urgent need of a low-cost, easy-to-maintain, quick-to-implement, and accurate counting device on conveying equipment.
