Tips for Effective Use of Checkweigher: The Photocell Error

Vol.14 Feburary, 2021

Technical Note Vol.14 Feburary, 2021Product inspection equipment use photoelectric sensors that identify each product to be inspected when it is conveyed. Anritsu's customer support center often receives phone calls from our customers regarding the photocell errors. In many cases, these errors can be prevented by proper cleaning and regular inspection.
This paper explains typical causes of the errors and countermeasures, while explaining different types of photoelectric sensors.

Tips for Effective Use of Checkweigher: A Zero-Set Error

Vol.13 December, 2020

Technical Note Vol.13 December, 2020Checkweigher automatically adjusts the system to indicate zero gram when there is no product on the weighing conveyor. However, Auto Zero sometimes fails due to several reasons like big change in temperature and humidity at the production plant, draft from an air conditioner, floor vibrations, etc. This paper explains measures for a zero-set error when using a checkweigher.

Cleaning and Maintenance on X-ray Inspection Systems That Can Be Easily Missed.

Vol.12 July, 2020

Technical Note Vol.12 July, 2020Generally, cleaning of production equipment prevents the growth of bacteria from food residue and stains. In terms of X-ray inspection system, proper cleaning also eliminates the cause of false rejects and extends the service life of the equipment. In addition, regular performance validation and maintenance provides a lot of important benefits.

This paper explains about cleaning and maintenance which users tend to overlook.

Metal Detector-Method for Fixing Test Pieces during Sensitivity Check

Vol.11 October, 2016

Technical Note Vol.11 October, 2016Those who use a metal detector can perform a sensitivity check by attaching a test piece on a product prior to the start of production. Detection of test pieces by the metal detector would vary depending on which position of a detection head (the tunnel where a magnetic field is generated) test pieces pass through. This paper will explain how the detection of test pieces vary and how to fix a test piece on a sample product.

What is Relative Virtual Weight by X-ray Inspection Systems?

Vol.10 May, 2016

Technical Note Vol.10 May, 2016Have you heard of the relative mass measurement by x-ray inspection systems? Many of you may wonder why x-ray systems can virtually measure product weight. Relative mass is the value which the difference of density between x-ray images of the reference master product and the inspected product is converted into the mass. This paper explains the principles of the relative virtual weight measurement, usage, and cautions.

Quality Control with the Use of Checkweighers

Vol.7 July, 2013

Technical Note (For general use) Vol.7 July, 2013The primary purpose of a checkweigher is to measure the weight of products and reject unacceptable under or overweight products. In addition to measuring product weight, checkweighers can be also used for quality control purposes. This paper introduces how to improve the quality of your product using a histogram.

Checkweigher and weighing accuracy

Vol.6 September, 2012

Technical Note (For general use) Vol.6 September, 2012A checkweigher is widely known as an automatic machine that che cks the weight of items as they pass through a production line. Y ou may have one at your facility but if yours is not appropriate for your production line, it may undermine producti on efficiency. There are various technical parameters for a checkweigher including weighing rang e, conveying capacity, measurement accuracy and scale interval, among which this paper explains measurement accuracy along with basic functions of a checkweigher.

Phase and Auto Tracking - Countermeasures Against False Detection Vol.3 -

Vol.5 May, 2012

Technical Note (For general use) Vol.5 May, 2012Technical Note Vol.4 took up product effect as a factor contributes to false detection of metal detector, and introduced Auto-Tracking function of Anritsu duw metal detector, which prevents false detection by compensating for phase shift caused by product effect. This issue will explain what phase is all about and how Auto-Tracking function works on phase.
