Problems solved by technology

It has been found that in order to detect the complete transfer of product from the weighing conveyor to the delivery conveyor, software algorithms of the type currently in use tend to be biased by the inconsistent data provided by the front arches or LED arrays, and by the flat or single pair rear sensor structures described above. disturbed by

Embodiment Construction

[0013] Referring to FIG. 1 , there is shown components configured to make up a self-checkout system 100 of an embodiment of the present invention. The system 100 is equipped with a scale-mounted weighing conveyor 102 for receiving, weighing and moving objects 104, which may be products, items, and the like. The system 100 may be used in stores selling various goods, but the present invention is not limited thereto. In general, the system 100 can be utilized wherever automatic verification or validation of an object as belonging to a particular object type, class or category is desired.

[0014] Typically, a scannable identifier, such as a barcode label 106 , is affixed to each object 104 to be read by a barcode scanner 108 . In one embodiment, the scanner 108 is fixed at a location in front of the conveyor to automatically scan the labels of the individual objects as they move through the scanner before being placed on the conveyor 102 . In another implementation, scanner 10...

Abstract

A vertical sensor array is placed along a weighing conveyer in a self-checkout system. Successive products are scanned and then placed on the weighing conveyer. As a product traverses the sensor array, a firmware control sends a measured height of the product to processor software, and also indicates the time taken by the product to pass the array. From the time, conveyer speed, and distance fromthe array to the end of the weighing conveyer, the software determines the time when the product will be transferred from the weighing conveyer to a location adjacent to the weighing conveyer. Since this transfer time is variable, depending on the product and the particular orientation of the product when it is placed on the weighing conveyer, the software can dynamically enable the scanner inputdevice for the associated system to accept the next following product or item. The software can accurately determine the correct weight of a product, even when multiple products are present on the conveyer simultaneously.

Description

technical field [0001] The invention disclosed and claimed herein generally relates to methods for authenticating a product or other object in which a sensor device, such as a vertical array of sensors, is used to determine the length of the product. More specifically, the invention relates to a method of the above-mentioned type, in which the products are scanned one after the other and then moved by means of a weighing conveyor through an array of sensors. Still more particularly, the present invention relates to a method of the type described above, which is conveniently used to regulate or control the processing speed in a self-checkout conveyor system. Background technique [0002] Self-checkout systems are increasingly being used by stores or other commercial establishments seeking to handle large numbers of customers with greater efficiency and reduced costs. Such a system can be used for many types of products as long as a barcode label or the like can be attached t...
