Monitors materials that are susceptible to stretching or web slippage
Applications:
Inspecting, monitoring and reporting in post-printing applications
Benefits:
Easy to Install
Move from one production line to another
Identify errors before they become scrap
Repeat Length Measurement System
The concept of the system is simple. Define the min/max repeat length that is considered “in-tolerance” for the job being inspected. Use a scanner to detect the registration mark on the material and make relative comparisons to the rotation of the press using an encoder. The Scanning Devices System Console compares the two measures, computes a ratio and alerts the press operator if the length between registration marks is out of specification. The system uses scanner and encoder data to calculate the actual length of the Repeat and accepts any unit of measure.
The system sends captured data to a computer using Scanning Devices software which can be exported to Excel for analysis and quality control reporting.
System Features/Capabilities:
- System includes, Electronic Console, Registration Scanner, Encoder, and Scanning Devices Software
- Measures variances in milliseconds for precision tolerance reporting
- Operator warning/indicator lights on Electronic Console illuminate green when material is in spec., red when pre-established min/max tolerances are exceeded
- Dimensionless system reports proportional variances without the need to convert to metric or imperial measures
- 110 volt system with 3 prong line cord allows the electronic consol to be easily moved from one press to another
- 15 to 50’ scanner and encoder cables available
- Console includes
- 16 Digit keypad
- 2 line display
Operating Console/Software:
- Two line display, presents measurement status (in or out of tolerance)
sequence number and measurement result
- Red and Green indicator lights indicate inspection error or in-tolerance measurements
- 16 digit keypad makes for fast system set-up
- RS232 interface transfers inspection parameters and results between PC and System Controller
- Scanning Devices software is easy to use and captures process data that can be displayed and analyzed in Microsoft Excel
Three different scanners work with Repeat Length Measurement Systems , covering many applications:
- CX6A - general purpose mark scanner for most scanning situations.
- CX7 - special purpose color contrast scanner for low contrast labels.
- CX8 - fiber optic scanner for small marks or hard to reach places.
