Definitions

  • Device of the invention relates to weaving machines, containing warp and weft yarns/tapes for fabric weaving on circular weaving machines, more precisely, sensing end of warp yarn/tape during fabric production.
  • the circular weaving loom or machine is designed to weave endless tubular or flat fabric using PP, HDPE, LLDPE yarn/tape or other blends of polyolefin ( Figure1 ).
  • the warp yarns/tapes are fed to the weaving machine-from more than one creel via rollers. This ensures uniform warp tension, excellent fabric quality, and trouble-free handling ( Figures 2 & 3 ).
  • the loose yarn/tape may possibly entangle with other nearby yarns/tapes coming from adjacent bobbins thereby damaging section of the running fabric.
  • one of the drawbacks of the existing systems is its requirement to regularly monitor bobbin exhaustion by operator.
  • another drawback of the existing systems is that when the ends of the warp are noticed, the machine needs to be stopped immediately such that the ends of the warp tapes are not allowed to reach reed ring section of the weaving machine.
  • Drop wire systems consist of a gravity-controlled 'drop wire' made of metals such as stainless steel through which the tape used for fabric making passes.
  • yarn/tape loses it tension which causes it to slag causing drop wire to fall down.
  • operator observes slag in yarn/tape and stops the machine to change the empty or semi filled tube with new bobbin.
  • one of the objects of the present invention is to provide an automated system for sensing warp end.
  • Another object of the invention is to provide an automated system for detecting warp end which will work robustly in dusty environment.
  • a further object of the invention is to provide an improved drop wire for the purpose of detection of warp end.
  • Another object of the present invention is to provide a system that reduces the wastage of weaved fabric and machine downtime.
  • the invention discloses a device for sensing an end of a warp yarn or tape on a fabric weaving loom according to claim 1.
  • the device is so designed that upon detection of a yarn end (due to yarn breakage or due to the yarn package running out of yarn) by a yarn detection means that is also a part of the device, an electric circuit is completed and a notification is sent to the loom operator.
  • the invention is particularly suitable in dusty environment in which CWMs typically operate.
  • the invention utilizes an improved drop wire (6) which maintains its normal operating position by hanging by the running yarn that passes through a loop provided at one end of the drop wire.
  • the drop wire is provided with an electrically conducting first element having a spatially curved external surface. Breakage of the running yarn causes loss of tension in the yarn, causing the drop wire to lose its elevation rapidly.
  • the device of the invention also incorporates a set of electrically conducting second elements having a curved internal surface. Upon the loss of elevation, the first and second elements come in electrical contact with each other, thereby completing an electric circuit and consequently causing a signal to be sent to the operator of the loom indicating yarn breakage.
  • Drop wires (6) are provided on every individual warp yarn/tape which is fed to the central reed ring section.
  • Woven fabric for use in making bags for storing materials such as grains, cement, etc. is made from yarn/tape of PP, HDPE, LLDPE or other blends of polyolefin.
  • a circular weaving machine/loom that makes tubular fabric for making such bags deploys a number of bobbins.
  • Figure 2 shows the typical yarn travel path in a CWM.
  • the device disclosed in the invention allows detection of ends of a broken yarn/tape so that the CWM may be stopped in order and a signal is sent to the operator on duty to avoid entanglement of the broken yarn/tape with other yarns/tapes operational on the CWM.
  • the key purpose of the device of the invention is to detect the breakage or end of a running yarn and inform the loom operator of its occurrence. This is achieved by providing the following three key elements in the device: a means to detect the yarn breakage, an electric circuit, and a notification means.
  • the CWMs operate in an environment where a substantial amount of particulate matter (dust) is generated as a result of loom operation. These particles settle on any available surface in the vicinity of the loom. The settled dust which is electrically non-conductive has the potential to hamper the loom operations. In the case of systems to detect yarn ends, where electric circuits are employed, the smooth working of such circuits may be hampered by such dust.
  • One of the key aspects of the device of the invention is that it works effectively regardless of the dusty environments within which they are deployed.
  • the present invention discloses a device for sensing end of warp yarn or tapes on an automated fabric weaving loom and notifying the instance of yarn breakage to the operator. It comprises a yarn end detection means to detect the breakage of or a slack in running yarn, an electric circuit, and a notification means to notify breakage of or slack in yarn.
  • the yarn end detection means comprises an improved weighted drop wire (6) ( Figures 4A and 6A ) with an eye (6A) at its one end through which the running warp yarn/tape (9) passes, and which is held in substantially upheld position by the tension in the running yarn (9).
  • An electrically conducting first element (6B) is attached fixedly to the drop at a predetermined distance 'h' ( Figure 4A ) from the eye (6A).
  • the drop of the drop wire (6) from its normal operating position is substantial and irrecoverable.
  • the drop wire (6) drops vertically by a substantial distance from its normal operating position on substantial loss of tension in the running yarn (6) - sensing of the irrecoverable drop of the drop wire (6) represents yarn end detection.
  • a pair of electrically conducting second elements (7) (see Figures 5A/5B ) is provided as a part of the electric circuit that is referred to earlier.
  • the components of the electric circuit are the first elements (6B), second elements (7), an electronic circuit (8) that electrically connects two second elements (7) of any pair of the second elements (7) at one end of the second elements (7), and a source of electric power. It further comprises an electric switch or a loop that is yarn-dust-proof. During the normal working operation of the loom, the electric switch/loop remains 'open'. The device is so designed that upon detection of a yarn breakage or a yarn end, the electric switch/loop closes effectively thereby completing the electric circuit - regardless of the presence of dusty environment. Upon closure of the electric circuit, an alarm is raised and a signal is sent to the operator indicating the yarn breakage.
  • the drop wire (6) supports a first element that has an electrically conducting outer surface (6C).
  • the outer surface (6C) of the first element (6B) is spatially curved ( Figure 6A ), preferably substantially in the form of a cone of any type.
  • the outer surface (6C) may have serrations that run substantially longitudinally.
  • the yarn-dust-proof electric switch/loop comprises a pair of electrically conducting second elements (7).
  • the second elements (7) are provided with inner curved shaped surfaces (also termed as inner surfaces or inner shaped surfaces) (7B) with a shape that corresponds to the outer surface (6C) of the first elements (6B).
  • the term 'corresponds' mentioned above refers to the correspondence between the outer surface (6C) of the first element (6B) and the shaped inner surface (7B) of the second element (7), and is to be understood in the context of electrical connection.
  • the outer surface (6C) of the first element (6B) and the corresponding inner surface (7B or 7C) on the second element do not have to be 'exactly matching' - that is they do not need to be in full contact with each other.
  • correspondence it is meant that there simply needs to be sufficient contact so that the electric switch/loop is closed effectively.
  • the dust tends to settle on surfaces that are, among other characteristics, devoid of geometric features such as points and sharp edges.
  • the inner surfaces (7B) of the second elements (7) are provided with points and/or sharp edges. Some of these are illustrated in Figure 7 .
  • the second elements (7) are in the form of a strip or a plate on which are provided the inner curved shaped surfaces (7B).
  • these plates When positioned across from each other, these plates, with the inner curved shaped surfaces (7B) facing the inner curved shaped surfaces (7B) of the other second element (7) from the pair of second elements, they form receptors into which the first elements (6B) fall when the drop wire (6) loses its elevation substantially.
  • the gap (7A) is so designed that the drop wire (6) passes through it in its normal working position without closing the electric loop.
  • the curve of the outer surface (6C) of the first element (6B) may of any shape, however it should be such that when the drop wire (6) drops from its normal working position, the first element (6B)------owing to the curvature of its outer surface (6C)------goes into the gap (7A) between the inner shaped curved surfaces (7B) of the two parts of the second elements (7) easily.
  • the curvature of the outer surface (6C) should be of such shape that upon resumption of the tension in the yarn, when the drop wire (6) is pulled up back to its own normal working position due to the tension in the yarn, this upward movement of the drop wire (6) is carried out unhindered.
  • the inner curved shaped surfaces (7B) of the second elements (7) may be made of a single surface (7C) ( Figure 6D ) or multiple sub-surfaces (7D) ( Figures 6B/6C ).
  • the junctions between any two sub-surfaces (7D) are preferably in the form of a point (7E) or an edge (7F) (see Figure 7 ) that is preferably sharp.
  • Formation of points or sharp edges (7E and/or 7F) is important in order to not allow dust to settle on at least some part of the curved shaped inner surfaces (7B).
  • the vertical distance 'h' ( Figure 4A ) at which the first element (6B) is located from the running yarn (9) that supports a particular drop wire (6) depends on the overall configuration of the system of yarns. The distance should be such that upon yarn breakage detection, the circuit is closed within a reasonably short time period. The distance should also be such that there is no false alarm raised in situations where there is temporary loss of tension. However, there may be exceptional circumstances, where the loss of tension is due to abnormal or unexpected slack in an unbroken running yarn, where the drop wire (6) may drop sufficiently so that the circuit closes.
  • One feature of the present invention is its ability to distinguish between temporary slack in the warp and permanent breakage in the yarn/tape (9).
  • the yarn (9) resumes its normal operation once the slack is eliminated by the ongoing movement of the yarn (9). This may take a duration as small as 0.1 seconds and up to 2 seconds. Under such circumstances, it would be undesirable if the CWM shuts down simply because there was a circuit closure (which is typically indicative of yarn end detection).
  • the device is provided with time monitoring facility. Time from any given closure of circuit is monitored and noted. In the case where there's no opening up of the circuit following from a circuit closure event within a predetermined period, it is indicative of a situation involving a yarn end or other undesirable event that suggests that it would be potentially harmful to allow the CWM to continue operation without intervention. In such situation the CWM is made to shut down and a notification signal is sent. The signal may be sent to a monitor. In the case where there's opening of the circuit within the predetermined period, no notification would be sent, however, the CWM will be permitted to continue operation.
  • the inbuilt intelligent module eliminates possibility of any faulty alarm generation for temporary loosening in yarn/tape (9), and more importantly the consequent shutting down of the CWM.
  • Temporary slack of warp yarn/tape (9) is very common in weaving machines which on account of false alarms consumes significant amount of resources in terms of time and manpower utilization as machine get down for this time period, which is always desirable to avoid under any circumstances.
