The Circular Loom is an important machine in Plastics and Textile industries. The quality and quantity of the final product largely depends on these machines, hence it becomes absolutely necessary to monitor certain parameters around the clock. However every plant has large number of looms and it is not possible for Supervisor / Engineer to stand on each loom to monitor these parameters and take corrective measures. Our Loom meter just serves this purpose. The Loom Monitor monitors all the essential parameter of the loom. These Monitors (Max 128) can be connected to a PC, where all the data will be logged around the clock. This data can be further processed to generate various production, quality, and maintenance reports. The Loom Monitors (Max 128) can also be connected to a Printer Interface (supplied Separately) for printing Shift wise report directly on a 80 Col. Printer, without using PC. This is highly convenient for small Number of looms. Since all the data is available at finger tips, the Loom Supervisor role is effectively reduced to great extent. It is also a cost-effective replacement for mechanical length counter, giving a better accuracy and many additional features. The Cut To Length is feature is very useful for cutting rolls of exact size, which is an essential requirement in Woven Sack Industry.

The Loom Monitor is housed in extruded aluminum box. On the front, it has a large LCD 2X16 character display and a four key membrane keypad. On the back side, a 15 Pin `D' type connector for terminating various signal and 24 VAC input supply, Four LED to indicate the status of Input Signal, 9 Pin 'D' type connector to terminate the RS485 bus (optional feature) and a protection fuse. The heart of the Monitor is a Single Chip Micro-controller. The Monitor also has Real Time Clock with memory, which will retain the data in the event of power failure. The data can be retained for 10 years. The input signals to the Monitor are optically isolated to ensure adequate protection to Monitor from external disturbance. The LCD display is backlit to facilitate the easy reading in the night also. The input power supply to Monitor is 24 volt AC which is easily available in Loom control panel.

The loom Monitor monitors all major parameters of the loom like Production, Weft breaks, and Warp Breaks, Loom running and stopped time. These parameters are recorded on 2 or 3 shift basis around the clock. The built in Real Time Clock keeps the track of time, even when the power is disconnected and Shift Changes are set automatically at preset time. All the Loom parameters are stored in Non Volatile Memory and are retained in the event of power failure. The loom parameters are arranged on LCD display for easier viewing. The Monitor has PC interface for connecting multiple Monitors to a PC, where all the loom data is recorded. This data is further processed to generate various reports like Daily, Weekly, Monthly production. These reports can viewed using a standard browser like Internet Explorer or Netscape Navigator.

The length sensing is done through a Proximity Switch mounted on chain sprocket of First nip roller. The proximity switch and Clamp are supplied with the Loom Monitor. No Welding, drilling, grinding, cutting operation are required on Loom. When the Loom runs, nip roller carries the woven fabric, and chain sprocket rotates at proportional fabric speed. For every pulse sensed at chain sprocket, the counter in loom is incremented. This incremental can be set on from panel of Loom Monitor to adjust for the variation in length. Thus Loom Monitor can be accurately set to measure the length of fabric. The cut length Counter in Loom Monitor also gets this information and ultimately rolls of fixed length can be cut.
