1) About LCM Loom Controller:
A) General Description:
Loom controller is integrated unit to control different functions of circular woven bag loom. Have a
The powerful microprocessor 32, which is used to control start speed, basic operation of the loom and stores the
Different loom data for future analysis.
Two proximity sensors mounted on the main motor shaft and the motor shaft of the conveyor measure the speed, and on the base
From the speed of the main motor, the conveying speed is controlled to obtain the desired weft density of the fabric. The 32-bit
The microprocessor also takes care of the inertia of the loom with the PID loop, so that during start, Stop and the period of inch, Plot
Density.
B) The combined loom controller (LCM) following three different functions:
1) Interlocking & Fault Monitoring: PLC Functions:
* INCH, START, STOP Operations Event
* Weft Break, Weft End and Warp Break monitoring.
* Engine failure monitoring: Main engine, trailer engine, winder motor.
* Diagnostic LEDs for inputs and outputs for easy troubleshooting.
* Ready status indication.
* Display of faults and events on the LCD graphic display
* Provision of Star-Delta and AC drive for the main motor.
* Main motor speed adjustment provided by additional analog output.
A) "Max Loom RPM" can adjust the normal operating speed of the loom from 20% to 100%.
B) 'Inch Speed' can adjust the speed of the loom during the passage of 5 to 50%.
2) Electronic gear: Mesh control functions:
* Fabric production: Mesh control according to the required density of the weft
* PID operator for the control of mesh in the conditions of start, stop and inches.
* Rupture fracture.
* Special Facilities: Periodic Cramming of the fabric installation (if necessary).
* "Test Menu" for easy configuration and checking of running status parameters.
* 'Haul-off' manual installations to pull the fabric when the loom stops.
* Adjustment Easier * The density of the plot required time to time.
* Weft Break Compensation: The clutch function is not required on electronic loom when there is breakage of the weft.
3) Loom data: Recording and monitoring functions:
* Event count for Weft Break, Weft End and Warp Breaks.
* Delay count for events: Break Weft, Weft End and Warp Breaks.
* Calculation of efficiency (time efficiency) of loom work.
* Real time clock.
* Shift Adjustment and Shift (2 or 3 shifts per day): You can see current shifts and the latest 2/3 shifts reports.
* Current Day Report.
* Overall report.
* 'Cut to Roll Length' Facility: You can check the rolls of the required length and the length of the balance roll at any time.
* 'Ordering': You can manage the duration of the order to produce on individual looms.
2) Reference Technical Document List:
Together with the manual, the following technical documents are provided for an easy and complete understanding of
A) Various interlocks, b) Electrical connections, c) Troubleshooting, etc.
As and when necessary, please refer to the document.
* Interlock diagram (fault logic) for PLC functions
* Input description table
* Output description graphic
* 'Menu list' for the main menu, submenu levels.
* Suggested loom panel wiring scheme (3 pages)
3) Construction:
The loom controller is composed of high-contrast LCD graphic display (blue and white), 8 Tact keys for adjustment
And reading several parameters. Additional contrast makes the display readable in all light conditions. the
The graphic display also uses a higher font size for displaying the parameters of the loom when the loom is running. in addition
To graphical display, LED indications are provided for 8 digital inputs 2 pulse inputs, change performance indication
And 6 relay outputs and 'status' on the front of the loom controller with green, red and white LEDs, so that
Troubleshooting becomes much easier and faster due to this LED. A high bright white LED indicates the
From the loom and is visible from a considerable distance. In general, the design of the loom controller has been made
With operator comfort and easy maintenance in mind.
At the rear, all connections are terminated in polarized plug type so that, in case the loom controller
It needs to be replaced, it is not necessary to unscrew the cables. This reduces the loom stop time.
