AI Technical Summary

Technical Problem

Existing sorting systems face inefficiencies and reliability issues when handling unstable products like bags, as they often displace during sorting, leading to reduced sorting capacity and reliability.

Method used

A sorting system with a central control server and conveyor system that includes elongated carriers and controllable extruding bodies, using sensing elements to position extruders between consecutive products, ensuring precise sorting by controlling the extruder movement based on product dimensions and orientation, and utilizing a modular design with controllers for each combination.

Benefits of technology

The system achieves high sorting capacity and reliability by minimizing product displacement, allowing for efficient sorting of a large number of products per unit time, particularly unstable items like bags, by positioning extruders within the width of consecutive products.

Abstract

The present invention relates to a sorting system for sorting products. The sorting system comprises a central control server, a conveyor having successive movable combinations of elongated carriers and extruded bodies, and a product feeder. Each combination further comprises an extruded body moving device having a drive for moving the extruded body along the carrier. The sorting system comprises a controller for each combination or group of combinations. The central control server and the controller are configured to ensure that, during operation, the feeder and the conveyor are controlled such that a carrier associated with an intermediate combination located between two successive products is released from the two successive products and the extruded body moving device moves the extruded body to a position located within the width of the two successive products.
