Description

CONTROL SYSTEM FOR WEAVING LOOMS
AND DEEP LEARNING METHOD
This invention relates to a control system for looms for warp and weft weaving, in particular, for rapier type looms in which the shedding machine and the weaving machine each actuate relative devices the phasing of which must be suitably coordinated and in such a way as to avoid interferences and safeguard the mechanical condition of moving parts; the phasing between the two parts has operational margins within which the mutual position may be varied in order to optimize the operation of the loom.
More specifically, the invention relates to an integrated command and/or control system for the individual actuation of the shedding machine and the weaving machine which together constitute a loom suitable for carrying out the cycle for inserting the weft, which, when repeated in sequence, forms the fabric in the loom.
Types of warp and weft threads, warp/weft weave, fabric coverage factor and width of fabric are some of the characteristics which require specific adjustments of the machine in order to optimize the productivity and the quality in each application.
However, these adjustments must be carried out with the machine stopped, either before the start up by interrupting the operation of the machine during a work cycle, with a resulting waste of time and resources which has an adverse effect on the weaving costs.
According to prior art technology, the control of a weaving loom comprises one or motors and a series of mechanisms which allow the following functions of the loom to be performed:
- controlling the steady-state speed, with the possibility of selecting the value suitable for the needs of the textile product being processed;
- connecting the machine and the shedding mechanism (dobby or Jacquard loom) according to a phasing between the two parts which is suitable for the textile product being processed; - connecting the machine and shedding mechanism in reverse mode according to a phasing similar to that of the arrangement in forward mode;
- varying the phasing between the loom and the shedding mechanism according to the technological requirements of the fabric to be produced.
According to the prior art solutions, the control includes a pair of motors, of which a first motor is used to control the machine at standard forward speed during operation, a second motor is used for low speed reverse movement during the de-weaving phase, and a toothed electromagnetic coupling with an engagement position, which ensures a predetermined phasing between the machine and the shedding mechanism in both directions of movement. The phasing during the forward and reverse movements can be modified by intervening manually on the mechanical connections between the various parts of the loom.
Another prior art solution comprises the use of a series of gears for controlling the two parts of the frame (machine and shedding mechanism), which can be coupled in various combinations by means of the axial sliding of one or more of the above-mentioned gears on a dedicated shaft, and control devices for the correct coupling between the gears.
A third solution of conventional type uses a transmission line comprising a brushless motor, a flywheel, a brake/clutch and a mechanical control of the shedding machine from the control shaft. The phasing between the machine and shedding mechanism is fixed and can be varied manually by intervening on the mechanical parts. During reverse movement the members for transporting the weft are disconnected from the rest of the machine, which may be actuated with slow reverse movement for de- weaving.
A fourth prior art solution comprises the use of a main control motor connected to parallel control shafts, of the machine and the shedding mechanism, respectively, and the control shaft of the machine is connected to the machine and to the shedding mechanism by means of a clutch and a series of position sensors for the phasing between the two part of the loom. There is also an arrangement consisting of two gears, of which the first gear is mounted on the shaft of the motor and the second gear is mounted on a service shaft, coaxial to and aligned with the motor shaft and moved by the motor shaft by means of an electromagnetic coupling.
The aim of this invention is to make a control system for weaving looms and, in particular, for rapier looms, which allows the command and control of the individual actuation of various mechanisms which intervene in the cycle for inserting the weft, with variable mutual phasing, according to the technological needs of the weaving and the operational trend of the machine, with the possibility of individual variation of the movement of each mechanism connected to the control system and communication with other control systems in deep learning mode, thereby simplifying and improving the above-mentioned adjustment requirements.
Another aim of the invention is to make a control system for weaving looms which allows the weaving loom to learn, process and manage functional adjustments aimed at varying the work conditions, on the basis of data relative to optimum operations of the machine previously tested such as type of warp and tensions, type of weft and tensions, weft-warp weave, opening of the warp shed and times, causes of machine stoppages and relative stoppage times, work speed and variations during start-up and in operation, quality of fabric, ambient conditions and every other element useful for the purposes of the production efficiency of the machine and the quality of the fabric.
A further aim of the invention is to make a control system for weaving looms, as well as an integrated control system for individual actuation of mechanisms for forming the fabric, which is able to intervene with autonomous adjustments for each fabric to be produced during start-up or during weaving.
These aims are achieved by making a control system for weaving looms according to the appended claim 1.
Other technical features of the control system according to the invention are mentioned in the subsequent claims. Advantageously, the control system according to the invention uses a speed, position and torque control motor, which actuate the forward movement during the weaving phase, the reverse movement during the de-weaving phase and the slow movement during the control and adjustment phase of the weaving loom.
In practice, the command actuates the two parts of the machine (weaving machine WM which controls the shuttles for the transport of the weft and shedding mechanism SM which commands the opening of the warp shed), which are suitably coordinated by the actuation mechanisms.
Each of the above-mentioned parts includes a position transducer device, which is able to continuously send signals relative its position and its operational status to a central control system for the processing to be performed and the functional interventions to be carried out.
The control system collects operational data of the loom, such as the number and type of stops, the weaving speed, the discontinuity and/or quality of the fabric, etc., compares the data with a database inserted in a central logic, which contains the characteristics of the yarns and fabrics in production and the ambient conditions, and decides autonomously in auto- learning mode whether it is worthwhile modifying the operating parameters set at startup, such as, in particular, the driving speed, the phasing between the weaving machine and the shedding machine, any start ramp, etc, communicating with other control systems outside the machine in "Deep Learning" mode.
In the new work conditions, the functional data is compared by a central control system with the previous data and the theoretical data and the control system decides whether it is worthwhile carrying out any further adjustment to the machine set-up.
These checks and consequent adjustments occur independently within each individual loom due to the effect of the measurement of operational data and the software processing according to the "Deep Learning" technology, which, by means of a control system, intervenes on the actuating motor or motors, on the connection between the various parts of the loom on the basis of the data measured, such as number of stops per warp, types and positions connected, number of stops per weft and types connected to the functions of the shuttles and the individual colours in weft, as well as the causes of machine stoppage and relative stoppage times, speed of work and variations during start-up and in operation, quality of fabric, ambient conditions and every other element considered useful for the purposes of the production efficiency and quality of the machine.
Further characteristics and advantages of a control system for weaving looms according to the invention will more fully emerge from the description that follows and from the appended drawings, provided by way of example but without limiting the scope of the invention, in which:
- Figure 1 shows a block diagram of a first embodiment of a control system for weaving looms according to the invention;
- Figure 2 shows a block diagram of an alternative embodiment of a control system for weaving looms according to the invention.
With particular reference to Figure 1 , a first embodiment of the control system for weaving looms, according to the invention, comprises a device for actuating the weaving machine (VVM) 8 and the shedding mechanism (SM) 7, which includes a motor 1 with a single control shaft 2, on which are mounted the gears 3, 4 for the control, by means of respective control shafts, of the weaving machine 8 and the shedding mechanism 7, and a frontal electromechanical coupling, comprising toothed portions 5, 6, which are connected, respectively and by means of respective control shafts, on one side, to the gear 3 and, on the other side, to the weaving machine 8. The toothed portions 5, 6 can interface and connect according to the signals coming from the control system C.
The phasing between the weaving machine 8 and the shedding mechanism 7 is implemented by actuating the position coupling, with front gears, comprising the two portions 5 and 6, which are switched on or off following an electrical command coming from the control system C.
The control system C in turn receives the control signals transmitted by the parts 7 and 8 (weaving machine and shedding mechanism), which constitute the weaving loom, by means of transducer devices for the continuous position signalling, whilst a parking brake 9 intervenes during the phasing adjustments to ensure the precision of mutual positioning between the weaving machine 8 and the shedding mechanism 7.
In practice, each of the two parts (weaving machine 8 and shedding machine 7) send signals throughout the whole 360° arc with a resolution of 360 212 (or any greater precision, if necessary), so as to control every moment of the whole weaving or weft insertion cycle and to adopt phasing positions between the two parts controlled (weaving machine 8 and shedding machine 7) as a function of the technological needs of the fabric being produced.
The variation of the phasing can take place independently, when a stop for weft or warp occurs, or with an stop operated by the control system C, whilst the other types of work parameters can be modified with the machine working.
A further embodiment of the control system for weaving looms, according to the invention, which allows the operational weaving parameters to be modified in auto-learning mode, comprises the use of independent actuators comprising pitch control motors M1 , M2, which actuate, respectively, the weaving machine 8 and the shedding mechanism 7, which are in turn controlled by a control system C, which determines the speed and phasing in every moment of the weaving cycle or weft insertion cycle (Fig. 2).
In this case, all the adjustments of all the operational parameters for machine adjustment relative both to the weaving machine 8 and the shedding mechanism 7 can be carried out according to the movement order.
From the description, the characteristics of the control system for weaving looms, according to this invention, clearly emerge, as do the advantages thereof.
More specifically, the system according to the invention is able to measure and modify the phasing and the adjustments of the parts (weaving machine and shedding mechanism) which make up the loom, intervening automatically in auto-learning mode according to the operational data recorded with the machine in operation, compared with equivalent theoretical data entered in a central control system, as well as with data of other control systems with which the central control system is able to communicate.
On the other hand, the central control system optimizes, with suitable adjustment modifications, the productivity and the quality of the fabric being produced, implementing suitable interventions by means of modifications of the adjustments of a motor and a position electromechanical coupling or of two motor which actuate, respectively, the weaving machine and the shedding mechanism.
Lastly, it is clear that numerous other variants might be made to the control system in question, without forsaking the principles of novelty of the inventive idea, while it is clear that in the practical actuation of the invention, the materials, the shapes and the dimensions of the illustrated details can be of any type according to requirements, and can be replaced by other technically equivalent elements.
