Description

A System And Method To Monitor Tape Breakage
Field of Invention
The present invention relates to a cost effective slit film tape yam breakage monitoring system and more specifically relates to method of identifying the tape breaks in multi-winder machine like extrusion tape-line or mono-filament line to alert operators for mending them. Further, the present invention provides on time and real time information on the productivity and downtime of individual winders and complete extrusion tapeline.
Background of Invention
The tape extrusion line or monofilament lines involves plurality of winders working in parallel for winding of tape/yam made from monolayer or multilayer endless flat plastic film/sheet of PP, HDPE, LLDPE or other blends of polyolefin. Due to inherent variability in the process, variety of operation conditions and raw material recipe been processed, there may be random disruptions to the process due to the potential breakages of the yarn/tape. This type of breaks requires manual mending or re-threading before the process can be re-started. Any delay in mending adversely affects the overall production. The delay also leads to wastage of raw-material which leads to substantial monetary loss and productivity loss.
It is conventional to employ human operators on such machines for monitoring/patrolling and mending of breaks. However, it has been observed that major time of operator is engaged in identifying specific instances of breaks, which increases the average time elapsed before a break end is mended/re threaded.
There are systems available for stopping of winder after the yarn/tape break. However, there is no system of tape break monitoring in tape extrusion line. Further, there is no system for providing real time information on the yarn/tape break and downtime of winders.
Objective of Invention
The main objective of invention is to provide device and method for identifying tape break on winder and providing information of winder location.
Another objective of invention is to monitor the time required for mending and real time information on productivity.
Further objective of invention is to monitor one or more complete extrusion tapeline and their plurality winders and provide required on time and real time information to client devices.

According to this invention, independent of specific winder type, a sensing module (2) is mounted with minimum modification to the existing winder (1). The sensing module (2) senses the presence of yam/tape (1A) and working of winder. Irrespective of how yarn/tape break is detected, the sensing module (2) communicates real-time information on yarn break and location to the operator working/patrolling on the machine. As soon as the tape break is mended and restarted the sensing module (2) monitors the time elapsed and real-time data is updated. Further, the system updates the information on downtime of winder and productivity of the machine.
The device and system as per the invention comprises of sensing module (2) and a communicating device (3). The sensing module (2) may be used to monitor one or more winders (1). The communicating device (3) enables sensing module (2) to communicate the information of tape break to a computing device (4) or the like in real time. Further, it is capable of monitoring elapsed time between tape break and rethreading of tape on same winder (1). The communicating device (3) is also capable of communicating signal of winder location with break to operator and updating information on computing device (4) or server which can further communicate with a client device. The communication may be facilitated using LAN based or cloud-based systems.
The invention enables sensing of tape break or winder stoppage by suitable electronic sensor means and storing of data/event in data processing/computing unit. Events such as breakage of tapes, instances of machine stoppage, time taken for winding a bobbin, time taken for rethreading after tape breakage, tape breakage instances per hour, total downtime for a winder or a single spindle or a group of spindles.
The client device includes computers, smartphones and other remote communication device or graphical display device (6).
Sensing modules may work on principles of optics or electro-magnetism or photo cell. In particular, the sensing modules may sense breakage in a tape on the basis of disruption to an optical beam or electro-magnetic field caused by break in a continuously running tape. For example, an optical signal may be obstructed by a running tape. However, when the tape breaks, the optical signal may be able to complete a circuit and allow the sensor to register the event of breakage. Similarly, in the case of a steady electromagnetic field through which a running tape is passing, the breakage of the tape may disturb the electromagnetic field - the disturbance allowing the sensor to register the breakage event,
Such events as breakage of tapes/yam, instances of machine stoppage, time taken for winding a bobbin, time taken for rethreading after tape breakage, tape breakage instances per hour, total downtime for a winder or a single spindle or a group of spindles are communicated and logged in main central data processing unit through which required format reports can be generated. For example, report given in Figure 2.
