Built-in communications functions allow the MR5500 to be linked to a quality inspection system to reduce total costs (time, labor, and materials)!
Nireco has built this controller based on many years of experience with control technology. The MR5500 detects register marks using high-performance optical fiber detectors, and controls the printing register to a high degree of precision.
Operation is by touch-screen LCD panel. You can set the system up by following the instructions on the screen.
Can be linked to a Nireco quality inspection system to achieve "integrated management" in the gravure printing process
- The automatic MR5500 register control system has built-in communications functions. It can be connected to print quality inspection systems or print still-image devices to achieve integrated information management and smarter operation.
The operation panel can be removed and operated separately from the console
- The operation panel, which is a flat screen LCD, can be removed from the console and operated in a convenient place for the operator, e.g., on the operation desk of the printing press.
FSP (First Search and Preset) substantially cuts down on the amount of waste created
- It has until now been impossible to check for position of initial plate setting before all of the colors start printing. The FSP function makes it possible to check the plate positions after printing only one or two colors, cutting down on the time spend and material wasted during initial set up.
Automatic recognition of registration marks
- The registration marks are automatically recognized on the moving web.
Rapid, optimum corrective action
- The optimum predictive control will be provided for each web type.
Extraordinarily easy for the operator to use
- Every system function can be performed by the operator on the touch screen LCD panel.
- A waveform display gives the operator an immediate representation of the registration, even at very low speeds. The display is switchable between sowing the waveform for one complete plate cylinder revolution or the waveform near the gate. Setting the gate is a one-touch operation.
- The name of each setting point is displayed when data settings are made.
- The icon-based operation is international understandable.
Different types of marks (vertical and horizontal) and web types are handled by one type of sensor
- Registration marks can easily be handled by changing an attachment at the fiber optics scanner.
Failsafe function guarantees stable operation
- When a major error occurs or when there is a large deviation in registration, such as a missing mark, the fail safe functions activated to maintain an extra margin of registration control.
- Parameter settings can be stored and later recalled when running the same product (up to 1000 data sets).
Analog deviation signal output
- Deviations signals are output as analog voltage (+/-5V) to allow recording.
Applicable with a double-sided and split-printing simultaneously
The MR5500 system consists of four main devices: control panel, optical fiber detectors, encoder unit and correction motor.
Only one encoder unit is used, regardless of the number of channels in the system. The encoder is installed so that it turns together with the plate cylinder. An optical fiber detector is mounted on each printing unit. There is one detector for the unit printing the standard color, and detectors for the units printing the second and third colors. The detectors send signals to the control panel. The controlling conditions are input into the setting screen on the control panel in advance. The controller receives these commands, calculates the deviation in the position of the register marks, and outputs correcting signals. The correction motor receives the correction signals from the controller. If the circumferential register control needs to be adjusted, the motor moves the compensator roller to adjust the printing deviation of the color concerned, and ensure that the register mark is in the proper position. In addition, if the lateral register control needs to be adjusted, the correction motor moves the plate cylinder to the left or right to compensate for any lateral shift in the printing position of that color.
