Each Checkrite is installed with a scanner and sensor, and the choice will be determined by the particular characteristics of each production line. More details are available from Axicon.
Before starting a production batch, a correct barcode is scanned and all subsequent barcodes must match this first one. A constant green light means that all the barcodes scanned match the stored barcode. If a different barcode is scanned, a red warning light will show, and the system can trigger an audible warning or line-stop. Missing or unscannable barcodes will prompt an amber warning light. The normal functions are set by the key-operated three-way switch which means that only key holders can operate the system. The system can be switched off for non-barcoded products. Ethernet communications can be provided as an option on Checkrite 7 units.
Recording the barcode to be matched is very simple. The three-way switch is set to ‘Learn’ and the barcode is passed in front of the scanner. The barcode data is recorded automatically.
The switch is set to ‘Run’, and if subsequent barcodes are identical to the first one, the green light will switch on and stay on until the next product passes the scanner
If the barcode being scanned does not match the stored barcode, the red light will switch on, and stay on until the switch is set to ‘Reset’. A relay with isolated contacts will also be activated, and this may be used to stop the conveyor or activate an ejector arm.
If a barcode is missing or unreadable (for whatever reason) the amber light will switch on and stay on until the next read cycle. After a programmable number of consecutive no-reads (usually five) both the amber and red lights will switch on and stay on until the switch is set to ‘Reset’. The relay, as with mis-match, will also be activated.
