Package-following-prevention dynamic scale package feeding control method and system

Abstract

The invention discloses a package-following-prevention dynamic scale package feeding control method and system. The package-following-prevention dynamic scale package feeding control method combines the judgment of the data integration condition and the triggering of a package through a photoelectric sensor to perform the starting control of a cache conveying line, and when the data integration is normal, whether the data integration triggering is completed firstly or the photoelectric triggering is performed firstly, the optimal bag supply efficiency of the cache conveying line can be kept; and when data integration is abnormal, a through hole controls the cache conveying line not to stop conveying, and sends a signal to start the cache conveying line to carry out package loading after abnormity processing is completed, so that the problem of package following is effectively solved, the problem of data confusion of multiple packages caused by continuous package supply of the cache conveying line is avoided, meanwhile, package damage caused by package collision is avoided, and the whole method gives consideration to the package loading efficiency, the timeliness of abnormal condition processing and the security of the package.

Description

[0001] Instructions for Divisional Application [0002] This application is a Chinese invention patent with an application date of October 30, 2019, an application number of 201911045170.0, and a Chinese invention patent titled "Anti-following package dynamic scale package control method, system, and anti-shaped parts false triggering of DWS cross-belt package line" Divisional application of the application. technical field [0003] The invention relates to the field of cross-belts, in particular to a control method and system for dynamically weighing and uploading packages for anti-following packages. Background technique [0004] The cross-belt sorting system is connected by the main drive belt conveyor and the trolley (referred to as "cart") carrying a small belt conveyor. When the "cart" moves to the specified sorting position, it rotates The belt completes the task of sorting and sending out the goods. Because the main drive belt conveyor and the belt conveyor on the ...

Problems solved by technology

[0006] The problem with this control method is that the control device needs to integrate the routing information, weight information, volume information and reserved trolley information of the parcels collected by the DWS conveyor line, and the data integration takes a certain amount of time. If the data integration Abnormal, and the data integration abnormality is only discovered after the package passes through the sensor. The abnormal data of the current package can be handled by stopping the transmission line behind the DWS transmission line, but the abnormal processing time of the package is not certain. At this time, due to the DWS The sensor on the conveyor line has been triggered by the current package, so the upper package conveyor line will start to transport the next package to the DWS conveyor line. When the next package passes the sensor on the DWS conveyor line, the upper package conveyor line will start again and will A package is transported to the DWS conveyor line, so reciprocating, as the package continues to enter the DWS conveyor line, the sensor is continuously triggered, and the package delivery line is also continuously uploaded, causing the problem of tracking the package, which affects the data of the system Processing accuracy, at the same time, there will be collisions between packages due to the stop of the abnormal handling conveyor line, which will easily cause damage to the package and its contents, affecting the safety of the package
