Detection display method and detector for inspecting book label on collating machine

Abstract

When each copy is delivered, the copy is measured and calculated with measuring inductor; and measurement data are compared with those in the N times of fore measurement. The deviation value is calculated for each measurement and based on the comparison between the deviation value and the set value, the copy is judged in being qualified or not. The present invention adopts automatic detection to replace available manually detection and can raise the work efficiency of collating machine and avoid misoperation.

Description

Technical field [0001] The invention relates to a detection method and a detection device used on a collating machine to detect whether a signature is qualified. Background technique [0002] In the past, the allowable value range of the pass or not of the collating machine was set by the operator based on the paper quality, printing type, density and other conditions of the signature, and the allowable value was manually set as the test standard. However, even a skilled operator cannot accurately determine and set the most appropriate allowable value for a variety of signatures. Not only the changes in the signatures, but also the characteristics of the collating machine itself will cause the signatures to shift. Therefore, it is very difficult to manually set the most appropriate allowable value. If the manually set allowable value is too small, even normal signatures will frequently display abnormalities, and the collating machine will frequently stop, which will reduce the pr...

Problems solved by technology

[0002] In the past, the setting of the allowable value range of whether the collating machine is qualified or not is all judged by the operator according to the paper quality, printing type, density and other conditions of the signature, and the allowable value is set manually as the detection standard. However, even for skilled operators, it is difficult to accurately judge and set the most appropriate allowable value for various signatures.

Not only the change of the signature, but also the characteristics of the collating machine itself will cause the signature to shift, so it is very difficult to set the most appropriate allowable value manually

If the allowable value set manually is too small, even normal signatures will frequently display abnormalities, and the collating machine will stop frequently, which reduces production efficiency. On the contrary, if the allowable value is set too wide, it will not be able to An unqualified section is detected, so a false detection occurs
