Definitions

  • the present invention relates to a modulated drive weaving loom and to a weaving controlling method employing said loom.
  • the drive system of a weaving loom comprises at least one main motor able to actuate a main shaft by means of a suitable friction clutch and a flywheel.
  • the main shaft in addition to transmitting motion to the main components, such as the sley and - in gripper looms - the actual grippers, drives also to secondary shafts which control other components, for example the weaving machine.
  • one or more auxiliary motors may be envisaged for operation of the loom at a slow speed or in reverse.
  • Said weaving looms equipped with direct-drive systems allow the weaving program to be set according to the physical characteristics of the yarn and the surrounding conditions in which the said looms are operating.
  • a further requirement occurs in natural, synthetic or artificial flock yarns which have a relatively low strength and therefore in any case result in the need for a sufficiently low insertion speed of the weft yarn and consequently low speed of the entire loom.
  • the Applicant has instead decided to abandon the usual approach, investigating totally new areas and leaving aside the established findings and theories which existed hitherto in this field, in order to be able to obtain a loom which overcomes at least partially the drawbacks of the prior art.
  • US 5.522.434 discloses a textile loom wherein a the main drive member of the loom is accelerated or retardated through a magnetic switching of electric motor operating alternatively as a direct-current motor or a direct-current generator.
  • the object of the present invention is that of obtaining the maximum benefit from the direct-drive system by providing a direct-drive loom which is controlled in an efficient manner so as to obtain the best result in weaving terms.
  • This result is achieved by departing in an original manner from the traditional approach of attempting to achieve continuity and uniformity of operation and instead searching in an original and inventive manner the best possible way of exploiting the new capabilities and flexibility offered by a direct-drive loom.
  • a new technology for controlling the motor is implemented, said technology exploiting the possibility of varying, within a cycle or over several cycles, the speed of the said motor - and therefore at least the main shaft of the loom - so to vary correspondingly the motion law of the main weaving components (sley, grippers, heald frames) associated therewith.
  • a preferred embodiment provides that the variation in speed is advantageously managed so as to increase the duration of the insertion period of the weft yarn (a phase which is undoubtedly critical for the quality of the final fabric) as needed and correspondingly shorten a portion of the working cycle which is less critical (for example beating-up) in order to recover "lost" time.
  • a direct-drive loom where the speed of rotation of the single motor is varied within one or more cycles.
  • the speed of the motor is varied within the cycle on the basis of the requirements of a main weaving component, the motion law of the other components being determined on the basis of the former.
  • the speed law curve of the motor so as to obtain the desired motion law of the grippers using a mechanism which is simplified and cheap (for example, in the case of the screw mechanism a system with a constant pitch, instead of a variable pitch may be used).
  • the average operating speed of the loom is nevertheless constant.
  • the motor speed is varied so as to satisfy "on average" the overall operating requirement of the loom, optimising the general behaviour thereof; for example, as already mentioned, by obtaining a reduction in speed during the part of the cycle where insertion is performed, so that a greater amount of time is available with the sley in the backward position and correspondingly a greater amount of time is available with the shed open.
  • This situation is particularly convenient for those articles woven using an air jet loom (for example synthetic yarns) for which the phase of crossing-over of the yarns coincides with or is slightly different from beating-up time of the loom.
  • the motion law of the motor is gradually varied from one cycle to another, for example in order to take into account the variations in the unwinding characteristics of the weft yarn between the fill and empty reel; in particular, the period of time during which the shed is kept open for insertion of the weft is gradually reduced upon reduction of the yarn still stored in the reel.
  • a dual-drive loom i.e. with one drive for the main components and another drive for the weaving machine - in which an independent variation in the speed of the two main motors of the loom is established so as to regulate and vary independently the motion law of the loom and the weaving machine and reduce further the need for replacement of the mechanical control components (for example, cams and kinematic mechanisms) in order to achieve a greater operating flexibility and efficiency.
  • the mechanical control components for example, cams and kinematic mechanisms
  • the invention provides a method for controlling weaving of a loom in which the instant of arrival of the weft yarn is detected by means of suitable sensors (for example, photocells, etc.), establishing the statistical progression of the weft arrival over time and modifying the speed, within a cycle, of at least the main motor (if necessary also of the weaving machine) in order to alter the duration of the time available for insertion on the basis of said establishment.
  • suitable sensors for example, photocells, etc.
  • Yet another aspect of the invention relates to a method which envisages determining the motion law of the main motor on the basis of strength parameters of the weft yarns so as to establish - for each single weft (in the case of an article which envisages the insertion of several wefts with different strength characteristics) - the proper and sufficient time for insertion of the said weft, with the correct air flowrate so that the yarn does not break, correspondingly increasing or reducing in an optimum manner the time available for insertion.
  • the direct-drive motor for driving the main components of the loom is controlled and regulated so as to vary the speed according to different criteria, with the aim of taking into account the effect on the actuated components in mechanical and weaving terms, without however neglecting the aspect of energy efficiency.
  • the speed of the direct-drive motor of the loom is varied according to a given motion law which is identical for each cycle.
  • the speed law is defined so as to control in the desired manner a specific weaving component, for example the motion of the gripper couple of a gripper loom.
  • the grippers may for example be controlled by means of a screw device having a constant instead of variable pitch, while the optimised motion law during insertion is achieved by means of adjustment of the motor speed.
  • a corresponding specific cam profile for actuation of the sley and the weaving machine is designed, so as to obtain the desired optimum motion laws.
  • the motor speed law or profile is defined so as to optimise the behaviour of the loom, mainly in weaving terms.
  • an example of a law profile may envisage a linear behaviour of the speed of rotation, with a maximum at beating-up (0° of the loom) and minimum at 180° of the loom. In this way the required motor torque is constant with a deceleration from 0° to 180° and constant with an acceleration from 180° to 360°.
  • This basic law may then be modified to include several variations in speed of different amount and also different shape (sinusoidal, polynomial).
  • the solution of the invention results in considerable advantages in terms of mechanical simplification, flexibility of use (hence greater rapidity in change-over of the article), reduction in costs; the constant-pitch screw already per se offers a clear benefit compared to a variable-pitch screw, with an improvement in the sliding block/screw connection with lower hertzian pressures and therefore an increase in the reliability (i.e. less play resulting from wear and greater duration); in the second case mentioned, advantages in terms of productivity and yield are obtained.
  • the speed law is varied from one cycle to another.
  • a device for controlling the arrival of the weft comprising two photocell sensors by means of which it is possible to detect deviations of the real values of the weft arrival time from the estimated values.
  • By processing these values over time it is possible to define a behaviour curve for the arriving weft yarn (depending on environmental factors, physical characteristics of the reel, etc.) on the basis of which suitable variations to the speed of the motor may be introduced.
  • an air control device is provided on the air jet nozzle, it is possible to co-ordinate the variation in speed of the motor with flowrate and insertion duration parameters within the permitted maximum values for the specific yarn.
  • the modifications of the speed of the motor over time may moreover be defined on the basis of suitable statistical functions which use as a parameter, in addition to the shed opening times and to the signals supplied by the weft arrival sensor, also an index relating to the number of weft breakages over time.
  • the loom is equipped with a dual drive system, namely it has a first motor for the main weaving components (for example sley for the air jet loom; sley and gripper for the gripper loom) and a second motor for the weaving machine, both being mounted with a direct drive system.
  • the first motor is designed to "track and follow" (positionwise or speedwise) the second motor, whereby the latter must normally have a greater power.
  • said variations in speed of the two independent motors of the loom and the weaving machine are correlated with the statistical data as to the type and number of weft/warp breakages detected by the control system.
  • the motions of the warp yarns - defined by means of the weaving machine - are more or less rapid as a function, among other things, of the various articles. Said motions are obtained at present by means of special mechanisms of the weaving machine (cams for dobbies and external gears, jacquard modulators, etc.).
  • variable speed profile is employed, with a - for example - linear, sinusoidal or polynomial profile, so that it is possible to obtain different motions of the warp yarns by modifying the parameters of the motor instead of replacing the abovementioned mechanisms (cams, etc.).
  • variation in the motor motion law is suitably set as a compromise between the various requirements, which include minimising the torques to be applied to the motor, not exceeding certain load limits in the dynamic behaviour of the system, and optimising the motion laws of the various weaving components (grippers, reed, weaving machine).
  • a variation in speed of +/- 150 rpm (which requires a nominal torque of the motor equal to about 100 Nm) produces a deceleration equal to 7.7% in the case of a linear variation and a deceleration of 12% in the case of a sinusoidal variation (corresponding to about 18 degrees or 4 milliseconds at the average speed).
  • the percentage decelerations (during the weft insertion phase) correspond to an equal percentage increase in the loom throughput value.
  • a variation in the motion of the loom is produced in such a way as to allow optimum operation of the various weaving components, therefore making it possible to achieve a textile product having an improved quality and lower cost.
  • the method of the invention it is possible to relate the variation of the speed profile (for example of the weaving machine of a dual-drive gripper loom) to statistics relating to breakage of the warp yarns (in particular to the ratio of breakage in the side zones to the total yarn breakages), said statistics being determined by means of a controller device.
