Definitions

  • This invention relates to a method and device for automatically controlling the quantity of at least one yarn fed to a textile machine operating discontinuously on it.
  • the invention is particularly directed towards those machines which form discontinuous products each of different colours and designs, such as hosiery machines or circular and straight knitting machines.
  • Such devices or feeders are to ensure a constant yarn consumption for all machine feeds, independently of the different yarn tensions created upstream of said devices due, for example, to the natural difference between the yarns of the different yarn bobbins which the machine generally uses during production.
  • Said feeders are universally known as positive yarn feeders. These devices cannot however be applied to all types of textile machine, and in particular to hosiery machines or to straight jacquard rib knitting machines. This is due to the fact that said machines not only require a continuous change of yarns (used overall to form the product), but also have to operate on yarns of different tension.
  • yarn accumulation feeders are known (negative feeders) which, although preventing breakage of the yarn unwinding from the bobbins when used, do not ensure constant yarn feed to the machine.
  • An object of the present invention is therefore to provide a method for feeding at least one yarn to a textile machine of the aforesaid type such that said feed takes place under constant yarn quantity.
  • a further object is to provide a method which is simple to implement.
  • a further object is to provide a device for implementing the aforesaid method which overcomes the drawbacks of known devices.
  • a particular object of the invention is to provide a device which enables one or two yarns fed to a textile machine of the aforesaid type to be operated in such a manner that the yarn or yarns are fed individually and in constant quantity to said machine for each piece produced.
  • a further object is to provide a device of low cost, simple construction and reliable operation.
  • a method for automatically controlling the quantity of at least one yarn fed to a discontinuously operating textile machine comprising:
  • the aforesaid method is implemented by a device for automatically controlling the quantity of at least one yarn fed to a textile machine operating discontinuously on said yarn, characterised by comprising first sensor means for determining characteristic data of the textile machine, second sensor means for determining the quantity of yarn directed to said machine, a control unit connected to said said first and second sensor means, and memory means connected to said control unit, this latter being connected to actuator means for the movement of the yarn to said textile machine, to control the operation of said actuator means in such a manner as to maintain the quantity of yarn which they direct to said machine constant.
  • a textile machine operating discontinuously on one or more yarns is indicated overall by 1; it is fed with yarns 2 (only one of which is shown in the figure) which unwind from respective bobbins 3 (only one of which is shown in the figure).
  • yarns 2 only one of which is shown in the figure
  • bobbins 3 only one of which is shown in the figure.
  • each yarn passes through a corresponding yarn guide 4 shown in dashed lines.
  • Each yarn 2 cooperates with a sensor 5 arranged to measure the quantity of yarn directed to the machine 1.
  • the sensor 5 is for example a movement sensor and comprises a roller over which the yarn passes via a known path; in this manner the quantity of yarn which has passed towards the machine 1 is known at each complete rotation of the roller.
  • the sensor 5 is connected to a control unit 6 to which the sensor feeds its obtained data via a line 7.
  • the unit 6 is advantageously a microprocessor connected via a line 8 to a random access memory or RAM 9 with which the microprocessor dialogues.
  • the unit or microprocessor 6 is connected via branches 10 and 11 to a velocity sensor 12 arranged to measure the rotational speed of the transmission shaft (not shown) of the machine 1, and to a sensor 13 arranged to measure the absolute incremental position reached by said shaft during the execution of the production cycle.
  • the velocity sensor 12 is for example a tachometer dynamo connected to the machine 1 via a branch 16, while the sensor 13 is an encoder connected to the machine 1 via a branch 17, said sensors 12 and 13 being suitably coupled to said transmission shaft.
  • a branch 20 terminating in a member 21 of known type (such as a microswitch), connected to the unit 6 via a branch 11.
  • the member 21 is arranged to indicate to said unit the termination (and hence the commencement) of a production cycle of said machine, ie when this latter terminates the production of each stocking.
  • the machine 1 is also connected directly to said unit 6 via a branch 23.
  • a display device 24 is connected via a branch 25 to said unit 6, which also receives a branch 26 (connected to earth at 26A) comprising contacts 27 and 28 which cooperate with a movable contactor 29 connected to a pushbutton 30.
  • Two further sensors 31 and 32 are connected to the unit or microprocessor 6 via respective branches 33 and 34. Said sensors are located between the yarn guide 4 and sensor 5 and, respectively, between the bobbin 3 and an actuator 35 for unwinding the yarn 2 from said bobbin, said sensors 31 and 32 detecting any breakage of said yarn 2 while moving towards the machine 1, or detecting an increase or decrease in the tension of said yarn.
  • the actuator 35 is also connected to the unit 6 via a branch 37; this actuator is of known type and can for example be a roller connected to an electric motor advantageously of stepping type, or a small impeller operated by compressed air.
  • the operation of the device of the present invention can be divided into two stages:
  • the device of the invention is able to ensure yarn feed with constant characteristics for all production cycles subsequent to the first acquired cycle, so ensuring that the products are perfectly equal to each other, and of length and quality identical to those determined during the first said stage.
  • the machine 1 is in the end-of-cycle position with the member 21, for example a microswitch (or the like), activated.
  • the unit is set to acquire data.
  • This unit sets an address line 9A connected to the RAM 9 to an initial position, for example 00, and awaits to receive a signal Vs from the member 21 indicating commencement of the production cycle.
  • the machine 1 is now operated so that it unwinds the yarns 2 from the bobbin 3 in the natural manner, ie unaccompanied by the respective actuators 35. In this manner the machine 1 produces a first product, defined as the master product.
  • the member 21 feeds the signal Vs to the unit or microprocessor 6.
  • the unit 6 deposits at the "zero" address of the RAM 9 two data items in binary number form, based on the signal generated by the sensor 5 and the tachometer dynamo 12, these data items representing the travelling speed of the yarn 2 with which said sensor cooperates, and the current machine speed.
  • the sensor 5 generates a signal V F along the line 7 corresponding to the travel speed of the yarn 2 towards the machine 1 and having a frequency proportional to the speed of the yarn 2, said signal being transformed into a binary number by the unit 6 and stored in the memory 9 via the line 8. If instead the sensor 5 were for example a sensor generating an analog signal (such as a tachometer dynamo), this signal would be converted into digital by an analog-digital converter before entering the unit 6.
  • this being directly fixed to the transmission shaft of the machine 1, is able to follow all speed variations of the machine and generate an analog signal V D proportional to said speed; the signal V D is suitably converted by an analog-digital converter (not shown) which could form an integral part of the unit 6, and is hence changed into a binary number which represents the sped of the textile machine. This binary signal is then deposited by the unit 6 (which receives the signal) in that location of the RAM 9 adjacent to the binary number representing the yarn speed as indicated by the sensor 5.
  • the unit 6 to which said encoder is connected increments the address of the next available location of the memory 9 to enable the data obtained by the sensor 5 (yarn speed) and the tachometer dynamo 12 (machine speed), and suitably converted by the unit 6, to be again deposited in it.
  • the encoder 13 by means of the angular position of the transmission shaft of the machine 1 (or another quantity), senses the formation of each portion of product by the machine. This sensed data item, fed to the unit 6, is then used by this unit as a signal of incrementation of the memory location.
  • the signals V F and V D are therefore stored, for each different product portion obtained, in different cells of the memory 9, with increasing addresses which are incremented at each successive signal V E reaching the unit 6.
  • the unit or microprocessor 6 reads the data contained in the first location of the RAM 9.
  • This location contains the two previously described binary numbers generated by the sensor 5 (yarn absorption speed) and by the tachometer dynamo 12 (machine rotation speed).
  • the sensor 5 and dynamo 12 generate respective signals (V F and V D ) representative of current data connected with the formation of the product.
  • the unit 6 calculates the exact percentage difference between these data to obtain a number which can be used as a correction constant with which to multiply the binary number corresponding to the yarn travel speed contained in the memory 9 location as previously determined by the sensor 5 during the self-learning stage or cycle.
  • the unit 6 uses the correct binary number corresponding to the exact speed which the actuator 35 must possess for the travel speed of the yarn 2 towards the machine 1 to be maintained constantly equal, or proportional should the tachometer dynamo 12 have sensed a different rotation speed of the machine 1, to that of the initial acquisition or self-learning cycle.
  • the purpose of this is to feed a constantly equal quantity of yarn 2 to the machine for each item produced, independently of any speed variation in the machine.
  • This comparison between current and master data is continuously repeated for each new pulse received by the microprocessor 6 from the encoder 13, using the data contained in the memory locations subsequent to the initial zero position for the machine operating point which has been reached, as indicated by said encoder.
  • the sensor 5 monitors the yarn speed to check that it is exactly equal to that calculated by the microprocessor 6 and set in the actuator 35 by this latter.
  • the microprocessor 6 is able to supply the operator, via the display 24, with information regarding the instantaneous yarn travel speed towards the machine 1 and the exact quantity of yarn fed to this latter during each control cycle.
  • the encoder 13 and the tachometer dynamo 12 can be replaced by a single encoder (or similar member), the frequency and number of the generated pulses of which can, by being processed in the unit 6, provide the data relative to the speed of the machine 1 and the absolute incremental position attained by it.
  • sensors 13 and 32 are also provided to monitor abnormalities in the yarn 2 during its movement towards the machine 1.
  • the two sensors 31 and 32 can sense both the tension and the breakage of the yarn 2 during its movement towards the machine 1.
  • the sensor 31 which, for example, can be in the form of a usual mobile arm cooperating with the yarn and with a microswitch, able to detect a slowing down in the yarn.
  • the sensor 31 detects an excessive increase in yarn tension by its mobile arm cooperating with a microswitch.
  • the sensors 31 and 32 In both cases, whether the yarn tension increases or decreases, the sensors 31 and 32 generate a signal (V A or V B ) which reaches the microprocessor 6. Following this, this latter generates a halt signal V K along the line 23 to halt the movement of the machine 1.
  • the signals V A and V B can be fed to a usual unit (indicated in dashed lines by 100) for controlling the machine movement, which halts said machine in known manner on receipt of the signal.
  • a usual unit indicated in dashed lines by 100
  • the sensors 31 or 32 detect this and halt the machine movement (in the described manner).
  • the unit 6 obtains data from several sensors 5 cooperating with all the yarns directed towards the machine 1, and operates on the actuators 35 for these yarns.
  • a plurality of units 6 can be provided connected to the sensors 5 and to the actuators 35 cooperating with each yarn, the dynamo 12 and the sensor or encoder 13 which generate the signals from the machine 1 then being connected to each of said units 6.
