Non-contact Flange Detecting System FA
Non-contact Flange Detecting System FA
The Uhing non-contact flange detecting system (FA) automates the correction of reversing points in rolling ring drives, enhancing efficiency and reducing operational costs in industrial applications by eliminating manual adjustments during spool changes or winding processes.
The system employs a sensor (light barrier) to detect coil flanges and trigger the reversal of the traversing unit. As the coil fills and the traversing shaft speed decreases, the stroke length is reduced. A PLC can compensate for this reduction, ensuring consistent performance.
- Power Supply: 85 - 264 V A.C., 47 - 63 Hz
- Compressed Air: 4 bar
- Uhing Rolling Ring traverse with pneumatic reversal mechanism
- Load carrier for sensors and material guide systems
- Light barrier with adjustable lead and telescoping swivel arm
- Relay controller for constant shaft speed
- Optional PLC for variable shaft speed control
The system is based on the Uhing rolling ring drive, converting constant shaft rotation into a traversing motion. It features a pneumatic system activated by a light barrier, which is interrupted by spool flanges to trigger reversal, automatically adjusting to spool variations and adapting reversal points.
- Constant traversing speed with a drive motor and bistable relay controller.
- Synchronization with decreasing coil speed using a belt drive, eliminating the need for a separate motor.
- Optional PLC for a standstill phase to prevent material dropping into gaps.
- Electric: 230 VAC, 50/60 Hz
- Pneumatic: 4.5 to 6 bar
- Mechanical: Proper alignment of the swivel arm and light barrier with the coil axis is required.
Ensure all connections are established. The system should switch over when the light beam is interrupted. Adjustments may be needed if the system does not operate as expected.
- Basic: Adjust the slide to match the flange diameter.
- Fine: Adjust the swivel arm angle for precise traversing stroke.
- Different flange diameters: Adjust by displacing the slide without changing the stroke setting.
The relay controller allows for time adjustments between flange detection and reversal, ensuring smooth operation and preventing errors during switching.
The document describes a bistable relay controller used in systems with constant speed and a separate drive motor. It alternates a 24 VDC voltage at two output terminals, switching based on a control signal at input E1. The relay retains its last position when de-energized.
1. Time Adjustment: The time 'ta' can be adjusted from 0 to 2 seconds using a 1 MOhm potentiometer. After 'ta' expires, the relay switches, changing the solenoid valve output from 24 VDC to 0 V or vice versa. Time 'tb' is adjustable from 0.2 to 2 seconds and starts after 'ta'.
2. PLC Operation: The PLC records speed changes on the traversing shaft and delays the switchover pulse to maintain constant traversing width. An optional pulse counter can be used for precise control.
3. Testing Inputs and Outputs: Set the PLC to 'RUN' mode to check signal status via LEDs. Inputs include speed capturing and light barrier interruption.
1. Light Barrier Sensor: Ensure proper installation and sensitivity adjustment as per the manufacturer's instructions.
2. Function Test: Verify the system by moving the traversing system to the middle and checking the output changes when the light barrier is interrupted.
Details on electrical connections for the PLC and relay controller are provided, including terminal designations and voltage requirements.

1. General information Your Benefit: -No readjusting of reversal points after spool change-No readjusting during winding -Easy to install -Low price The Uhing non-contact FA flange detectingsystem provides a cost-effective means to automate required corrections of rolling ring dri- ve reversing points tried and tested in conti- nuous industrial application.The traversing system incessantly distributingthe material between the spool flanges is only rarely regarded as a cost factor. This only occurs when a conversion to new material dia- meters or coil widths is necessary. The setting then remains...

Nimmt die Drehzahl der Verlege- welle mit zunehmendem Fllgrad der Spule ab, verkrzt sich der Hub, da die Umschaltzeit kon- stant bleibt. Um diese Hubverkrzung auszu- gleichen, kann eine SPS mitgeliefert werden. Function: A sensor (light barrier) detects the coil flanges and trips the reversal of the traversing unit.

This traversingsystem variant features a drive motor of its own and a bistable relay controller allowing the time between flange detection and reversing impulse to be adjusted. For notes on the relay controller refer to item 7.1. 2. Description 3.3 To prevent profiled material from droppinginto the gap between the last winding and the flange a brief stop of the traversing system before reversal is often useful.

Reversal system (6)and swivel arm (1) must switch over when the light beam (17) is interrupted.When the shaft rotates in the normal directionthe traversing system (5) must move into the direction of the swivel arm. In the adverse case you must swap the connec-tions of the swivel arm pneumatic cylinder after having unscrewed the clamping screws (16) and removed the slide (11). 6.

6.2 Fine adjustment Precise adjustment ofthe traversing stroke occurs by changing the angle (a) of the swivel arm (1) during winding. To do so turn the adju- sting screws (8) for each stroke direction accor- ding to the markings. Turning in +ԓ direction results in a stroke increase and morematerial being wound atthe flange. Use the sca- les (15) to verify the changes.To quickly find the optimum setting you mustcarefully observe the first layers in particular.
