Definitions

  • the present invention refers to a modular drive system for weft and warp weaving machines.
  • the invention regards an integrated drive and control system for the individual actuation of each mechanism of a set adapted to carry out the insertion cycle of the weft, which, sequentially repeating, leads to the formation of the fabric in a weaving machine.
  • the formation process of a weft and warp woven fabric fundamentally consists of inserting weft threads transverse to warp threads, which, with the aid of eyes or heddles in which a thread is inserted in each, are appropriately separated in positions arranged on different levels so to form a shed wherein a weft thread is introduced which is beat by a reed against the edge of the fabric being formed.
  • the heddles close, aligning themselves so to reopen in an analogous manner to that previously described but according to a different order, determined by the type of fabric weave which it is desired to produce.
  • Types of weft and warp threads, weft/warp weave, cover factor of the fabric, and width of the fabric are some of the characteristics which require specific adjustments of the machine in order to optimise its productivity in every application; such adjustments, nevertheless, must be made when the machine is stopped, before starting, and involve a waste of time and resources which penalise the weaving costs.
  • Object of the present invention is therefore that of realising a system of modular drives for weaving machines, which permit driving and controlling the individual actuation of each mechanism which intervenes in the formation process of the fabric, simplifying and improving the adjustment problems mentioned above.
  • Another object of the invention is to realise a modular drive system for weaving machines which permits driving and controlling the individual actuation of each mechanism which intervenes in the insertion cycle of the weft, with variable mutual phasing, according to the technological needs of the weaving, with the possibility of individual variation of the motion diagram of each servomechanism connected with the related mechanism and with devices adapted to obtain the energy recovery in the pulsating course of the typical drive torques of the weaving cycle.
  • Further object of the invention is that of realising a modular drive system for weaving machines which is of easy, compact, rational construction and of reduced size with respect to the prior art, adapted for functioning at high speeds, thus improving the machine's productivity.
  • Not last object of the invention is that of realising a modular drive system for weaving machines, as well as an integrated control system for the individual actuation of the fabric formation mechanisms, which permits utilising the machine for any type of weft and warp thread and/or fabric, intervening with quick and easy adjustments for every fabric to be produced, at the start or during the weaving.
  • each of the controls of the servo-drives is composed of two parts, one of which operates individually regarding the needs of the drive device to which it is assigned, while the second is integrated in a common base with the other controls regarding all shareable functions, which can be the power supply system, the communication system, the management and control system, the energy recovery system, the braking system for emergency stopping, etc.
  • the system can be advantageously applied to every type of weaving machine, such as rapier looms or machines and/or air jet looms.
  • the warp threads entering the rapier weaving machine are generically indicated with 1
  • the weft threads are generically indicated with 2
  • the fabric forming at the exit of the rapier weaving machine according to the present invention is indicated with 3.
  • a device for the formation of the warp shed is indicated with 4, a series of eyes or heddles are indicated with 4', in each of which a thread is inserted, adapted to separate the warp threads 1 into positions, the left hand gripper is indicated with 5, the right hand gripper is indicated with 6 and indicated respectively with 7 and 8 are a drive gear of the left hand gripper 5 and a drive gear of the right hand gripper 6; the left hand 5 and the right hand 6 grippers slide adjacent to the reed 11 of the sley.
  • the weaving machine also comprises a drive motor 9 for feeding the warp threads, a drive motor 10 for advancing the fabric 3, a drive motor 12 of the sley, a drive motor 13 of the left hand gripper 5, a drive motor 14 of the right hand gripper 6 and a drive motor 15 for the formation of the warp shed.
  • a reference and signalling device of the cycle phase is indicated with 16
  • an electric control box of the entire weaving machine is indicated with 17
  • the modular control system, according to the invention is indicated with 18 which comprises a common base 19, with the possibility of being subdivided in turn into modules which, in the example of the attached figures, are two and consist of the modules 19' and 19''.
  • the modular control system 18 includes, in addition to the common base 19, the servo-drive 9' of the drive motor 9 for the feeding of the warp 1, the servo-drive 10' of the drive motor 10 for the advancement of the fabric 3, the servo-drive 12' of the drive motor 12 of the sley, the servo-drive 13' of the drive motor of the left hand gripper 5, the servo-drive 14' of the drive motor 14 of the right hand gripper 6 and the servo-drive 15' of the drive motor 15 for the formation of the warp shed.
  • the warp threads 1 advance, powered by the drive motor 9, while the formation device of the shed 4 positions such warp threads 1 up high or low, so to form a shed, which permits weaving the warp threads with the weft threads 2 transversely inserted with the alternate motion of the left hand 5 and right hand 6 grippers (in the case of rapier looms) or by means of the devices consisting of pre-feeders and nozzles 20 and 21 (in the case of air jet looms), in order to realise the fabric 3; in the case of the rapier looms, the grippers 5, 6 are driven by respective drive gears 7,8, by the independent servo-drives 13', 14' integrated in the modular control system 18, and by the respective drive motors 13, 14.
  • the present invention realises a system of individual drives of the basic devices of the weaving machine (loom), integrated in a platform which groups together all of the technically shareable functions, with advantages in terms of cost reduction, high processing potentialities of the control programs, optimal capacities of compensating the pulse power flows and reducing the energy consumption, and finally with the possibility of putting the machine in a safe position in case of emergency.
  • the set of servo-drives 9', 10', 12', 13', 14', 15', integrated in the modular control system 18 and of the respective drive motors 9, 10, 12, 13, 14, 15, can operate in a closed-loop control system, synchronised by means of signals coming from the reference device 16 and/or from position or velocity transducers situated on the drive motors 9, 10, 12, 13, 14, 15, or a closed-loop system of "sensorless" type, synchronised by means of signals generated by the modular control device 18, or in an open-loop control system.
  • the drive of the sley is a direct drive between the drive motor 12 and sley mechanism 11, and the related servo-drive 12' can actuate the mechanism at constant or modulated rotation speed, as a function of the technological needs of the fabric to be produced.
  • the servo-mechanism of the formation mechanism of the warp shed composed of the drive motor 15 and by the related servo-drive 15', can actuate the heddles 4 with phasing and motion laws adjustable in real time, as a function of the technological characteristics of the threads and fabric 3.
  • the insertion of the weft 2 can occur by means of fluid-mechanical devices (not indicated in the attached figures), actuated by means of pressure timing and control systems, or by means of the grippers 5 and 6, actuated by servo-mechanisms, respectively consisting of the drive motors 13 and 14 and the related servo-drives 13' and 14'; the aforesaid servo-mechanisms, of compact structure and lacking complex and costly mechanical components, can be of position control type or of speed control type in electric gear or electric cam with other members of the machine.
  • the motion laws of the grippers 5 and 6, determined by the technological needs of the weaving process, in addition to that of the mechanical functionalities of the set, deriving from the dynamic loads due to the running and acceleration progressions of the various machine parts, are realised by means of software programs, with appropriate algorithms which make said laws adaptable, in a versatile manner, to the objectives of the present invention.
  • the unwinding system of the warp 9 and the leading system 10 of the fabric 3 are integrated, which have control servo-drives 9' and 10', specific for the parts necessary for the specific functions assigned to the them, while they use the potentialities of the common base 19 of the modular control system 18 for the functions which they can share with the other servo-drives 12', 13', 14' and 15'.
