Method and apparatus for verifying stack size

摘要

A method and apparatus for verifying stack size are disclosed wherein measured length and width dimensions of a stack of paperboard sheets are compared with length and width values of a label associated with the stack. The dimensions are typically measured as the stack travels along a conveyor. A no-match indicator is produced if there is not a match between the dimensions and values, and may include an alarm or a display on a video screen. The stack may be diverted to allow application of a correct label whereby the stack will be shipped to the correct customer.

主权项

1. A method comprising the steps of:
providing a first label associated with a stack of paperboard sheets, the first label comprising length and width values; applying the first label to the stack; measuring length and width dimensions of the stack with a measuring assembly; reading a machine readable code on the first label to access the length and width values; determining whether there is a match between the dimensions and values such that if there is a match, the first label is a correct label which includes correct customer shipping information and if there is not a match, the first label is an incorrect label which includes incorrect customer shipping information whereby using the incorrect label would result in shipping the stack to a wrong customer; if there is a match per the step of determining, shipping the stack to a correct customer in accordance with the correct customer shipping information of the first label; and if there is not a match per the step of determining, applying to the stack a second label which includes correct customer shipping information and shipping the stack to a correct customer in accordance with the correct customer shipping information of the second label.
