Definitions

  • the invention relates to a method of controlling the course of the lifting functions of the main mechanisms of a weaving machine, in which each of the mechanisms is provided with an individual drive, whereby each of the drives comprises a servomotor with a controllably variable angular speed during one revolution of the servomotor.
  • Fig. 4 shows the course of a stroke, for example the stroke of a batten of the beating-up mechanism, depending on the angle of rotation of the main shaft.
  • Fig. 4 shows an angle of the main (mechanical) shaft for weft insertion ranging from 75° to 285°.
  • This angle is the result of the specific geometry of a joint mechanism (dimensions of the individual members) or of the shape of a cam path of a cam mechanism and cannot be continuously changed.
  • CZ302120 discloses a weaving machine in which a multi-member mechanism for providing reciprocating motion of a weaving reed with reduced moment of inertia is coupled to a motor with a controllably variable angular speed during one revolution of the motor. A part of a shedding mechanism is also coupled to this motor with a controllably variable angular speed during one revolution during one revolution of the motor.
  • the relationship between the motion of the weaving reed and the respective part of the shedding mechanism, usually a heald rod is unchanged, and so everything mentioned above and shown in Fig. 4 also applies to this relationship.
  • the object of the present invention is achieved by a method of controlling the course of lifting functions of the main mechanisms of a weaving machine according to the present invention, whose principle consists in that the angular speed of the servomotor of the beating-up mechanism and the angular speed of the servomotor of the shedding mechanism change during their rotation according to the selected unevenness of operation according to adaptive algorithm, whereby in an exemplary embodiment, the value of the quadratic mean of the driving torque determined within an interval of one revolution of the main virtual shaft is maintained at the same selected level for all operating frequencies of the machine.
  • the quadratic mean of the course of the driving torque can be replaced with another dynamic parameter of the weaving machine, such as the quadratic mean of the performance, maximum value of the driving torque, maximum value of the performance, mean value of the driving torque, mean value of the performance, the loading of the members of the transformation mechanisms or the service life of the bearings loaded by reaction forces.
  • This solution allows to change the stroke dependence by an adaptive system and maximize the insertion angle, thus enabling operation of the machine at higher speeds, optimizing machine operation with respect to the insertion requirements of a specific weft material and effectively utilizing the dynamic properties of the weaving machine in a wide range of operating speeds.
  • Fig. 1 shows a basic scheme of a drive of a batten of a beating-up mechanism and of a drive of a heald rod of a shedding mechanism of a weaving machine for the production of leno fabrics
  • Fig. 2 shows the drive of the batten of the beating-up mechanism
  • Fig. 3 shows the drive of the heald rod of the shedding mechanism
  • Fig. 4 shows the dependence of the stroke of the batten, or of the heald rod z 41 on the angle ⁇ of rotation of the main mechanical shaft during one revolution of this shaft according to the background art
  • Fig. 1 shows a basic scheme of a drive of a batten of a beating-up mechanism and of a drive of a heald rod of a shedding mechanism of a weaving machine for the production of leno fabrics
  • Fig. 2 shows the drive of the batten of the beating-up mechanism
  • Fig. 3 shows the drive of the heald rod of the shedding mechanism
  • Fig. 4 shows the dependence of the stroke of the batten,
  • FIG. 5 shows the course of the angle of rotation ⁇ 21 of servomotor rotor on the angle ⁇ of rotation of the main virtual shaft during one revolution for the parameters of the unevenness of operation A% adjustable within a range from 0 % to 100 %
  • Fig. 6 shows the course of the dependence of the revolutions n 21 of the servomotor rotor on angle ⁇ of rotation of the main virtual shaft during one revolution for the operating frequency of the weaving machine 600 min -1 and the parameters of the unevenness of operation A% adjustable within a range from 0% to 100% and finally, Fig.
  • FIG. 7 shows the course of the stroke z 41 of a working member (the weaving reed in the case of a beating-up mechanism and the heald rod in the case of the shedding mechanism) depending on the angle ⁇ of rotation of the main virtual shaft during one revolution for the parameters of the unevenness of operation A% which are adjustable within a range from 0 % to 100 % and after the transformation by a crank mechanism.
  • the invention will be described with reference to an example of an air-jet weaving machine for producing leno fabrics.
  • it is not limited to this type of weaving machine, but can be used in all weaving machines to control the lifting functions of the main mechanisms, each of these main mechanisms having an individual drive with a controllably variable angular speed during one revolution of the drive.
  • the air-jet weaving machine for producing leno fabrics comprises a beating-up mechanism 1 and a shedding mechanism 2 .
  • the beating-up mechanism 1 comprises a weaving reed 11 which is mounted on a stringer 121 of a batten 12 .
  • the batten 12 is mounted in a known manner on the machine frame 3 by means of at least two flexible members 122 of the energy recuperation system of the beating-up mechanism 1 , as is schematically shown in Fig. 1 .
  • the flexible members 122 are arranged in two planar surfaces between which there is a spacing in the direction of the motion of the stringer 121 of the batten 12 between the insertion position and the beating-up position and the batten 12 is made according to patent CZ 302391 of a carbon-epoxy (CE) composite material or another suitable material.
  • CE carbon-epoxy
  • the flexible members 122 consist of leaf springs 1221 which constitute in their upper part an integral part of the stringer 121 , whereby both the leaf springs 1221 and the stringer 121 are made of the same CE composite material and form an open profile in the shape of a parallelogram or a general quadrilateral.
  • the beating-up mechanism 1 is provided with an individual drive which is in the illustrated embodiment formed by two servomotors 4 according to UV 29115 with crank rotors 41 which are at one end provided with eccentric pins 411 on which are mounted connecting rods 42 of the beating-up mechanism which are in the exemplary embodiment shown coupled to the batten 12 by means of connecting rod pins 123, formed on the batten 12 .
  • the two servomotors 4 with crank rotors 41 are controlled synchronously and have a controllably variable angular speed during one revolution.
  • the servomotors 4 with crank rotors 41 are mounted on the frame 3 of the weaving machine and, in the embodiment shown, are spaced from each other by means of eccentric pins 411 with connecting rods 42 .
  • the pins 123 of the connecting rod 42 are formed on the batten 12 below its stringer 121 .
  • a weaving reed 11 and related accessories, for example main nozzles 124 , blowing nozzles 125 , etc., are mounted on the stringer 121 of the batten 12 .
  • the servomotors 4 with crank rotors 41 are coupled in a known unillustrated method to an unillustrated control system of the weaving machine.
  • the shedding mechanism 2 of the weaving machine comprises a vertically reversibly displaceable heald rod 21 on which is mounted a guide rail 211 of stationary warp threads with holes to receive stationary warp threads which further pass through the lamellae of the weaving reed 11 to a binding point, where they become part of the fabric.
  • the heald rod 21 is coupled to the shedding mechanism with an individual drive with the aid of means which are situated below the weaving plane which is formed by a horizontal plane interspersed with the binding point.
  • the heald rod 21 of the shedding mechanism of the weaving machine is slidably mounted on the machine frame in guides (not shown) by means of gliders 23 which are fixedly connected to the heald rod 21 .
  • the individual drive of the heald rod 21 is formed by a servomotor 5 with a controllably variable angular speed during one revolution of the servomotor 5 .
  • the servomotor 5 of the shedding mechanism is mounted on the frame 3 of the weaving machine and located below the middle part of the heald rod 21 .
  • the servomotor 5 of the shedding mechanism 2 is provided with a continuous shaft 51 , at the ends of which are arranged crankshafts 511 , which are coupled to the heald rod 21 in a known method by means of the connecting rods 52 of the shedding mechanism.
  • the heald rod 21 is made of CE composite material.
  • the heald rod 21 of the shedding mechanism is associated with recuperative members 6 of the energy recuperation system of the shedding mechanism 2 .
  • recuperative members 6 are arranged below the heald rod 21 .
  • a central holder 60 of the inner recuperative members 601 is fixedly mounted on the frame 3 of the weaving machine, to which static stirrups 661 of the inner recuperative members 601 are connected.
  • the movable stirrups 662 of the inner recuperative members 601 are coupled to the connecting rods 52 of the shedding mechanism 2 by means of flexible tow bars 67 .
  • Outwards, flexible tow bars 67 of outer recuperation members 602 are mounted on the respective connecting rods 52 of the shedding mechanism 2 , whereby the static stirrups 661 of the outer recuperation members 602 are fixedly mounted on the frame 3 of the weaving machine in the extreme holders 61 , 62 of the outer recuperative members 6 .
  • the inner recuperative member 601 and the outer recuperative member 602 constitute on both sides of the machine a pair of recuperative members 6 which serves for energy recuperation of the shedding mechanism 2 .
  • the flexible tow bars 67 also move and carry the movable stirrups 662 of the respective pairs of recuperative members 6 , while the static stirrups 661 do not move, which leads to the deformation of the leaf springs 66 of the respective recuperative members.
  • the leaf springs 66 straighten and recover energy.
  • the adaptive system consists in the fact that due to the change of unevenness of rotation of the rotors of the respective servomotors depending on the operating frequency of the weaving machine, the maximum insertion angle is achieved, that is, the maximum space or time for the implementation of pneumatic weft insertion while making optimal use of the dynamic characteristics of the mechanisms of the weaving machine and their individual drives by the respective servomotors.
  • Fig. 7 graphically represents the course of the stroke z 41 of the working member (the weaving reed in the case of the beating-up mechanism and the heald rod in the case of the shedding mechanism) depending on the angle ⁇ of rotation of the main virtual shaft, during one revolution of the main virtual shaft for the parameters of unevenness of operation A% adjustable in the range from 0% to 100% and after the transformation by the crank mechanism.
  • the optimization solution of the problem was performed numerically, at discrete points for the varying parameters of unevenness A% and the practical range of nominal speeds of the main virtual shaft of the weaving machine, and subsequently approximated by continuous analytic function.
  • the other values shown in the Table are key physical quantities of the solved system and they also need to be critically assessed.
  • the optimization of parameters of unevenness of operation A% can also be performed for other dynamic parameters of the weaving machine, where the value of the dynamic parameter selected from the group of dynamic parameters: (the quadratic mean of the course of the driving torque, the quadratic mean of the performance, the maximum value of the driving torque, the maximum value of the performance, the mean value of the driving torque, the mean value of the performance, the loading of the members of the transformation mechanisms or the service life of the bearings loaded by reaction forces) and (the value) calculated for the interval of one period is maintained at the same selected level for all operating frequencies of the machine.
  • the method according to the invention can be used in weaving machines which have individual drives of the beating-up mechanism and the shedding mechanism, and both these drives are controlled in the electronic cam mode.
  • the method can also be used in weaving machines in which the drive of the beating-up mechanism and the shedding mechanism is common but consists of a servomotor controlled in the electronic cam mode.
