AI Technical Summary

Technical Problem

Existing weight sorting devices with integrated metal detectors require a long conveyance line due to the serial arrangement of metal detectors and weight sorters, necessitating a large installation space.

Method used

A weight sorting device with a metal detector that integrates a weighing conveyor and a metal detector along the transport path, using item detection sensors to determine the start and end of the weighing process, allowing simultaneous weight measurement and metal detection, with adjustable inspection modes for items of varying lengths.

Benefits of technology

This configuration enables efficient weight measurement and metal detection without a long conveyor line, reducing installation space and allowing for quick sorting of items based on weight and metal presence.

Abstract

To provide a weight selection device with a metal detector capable of simultaneously performing weight measurement and metal detection for an article without providing a long conveyance line.SOLUTION: A metal detector 5 is arranged in the middle of a conveyance path of an article by a weighing conveyor 4 so that a conveyor belt 9 of the weighing conveyor 4 is inserted through a detection space s of the metal detector 5; at the timing based on the output of first and second photoelectric sensors 35, 36, which are installed on loading and unloading sides of the article on the conveyance path of the weighing conveyor 4 and detect the article, a weight of the article is measured and a weight value is calculated; and the presence or absence of metal mixed into the article is determined to determine the quality of the article.SELECTED DRAWING: Figure 2
