    A yarn feeding apparatus for yarn-processing textile machines such as circular knitting machines has a feed element which advances the yarn with its circumference. The feed element is rotatably supported on a holder which is arranged to be secured on a carrier and has yarn guide and/or monitoring devices for the yarn being fed to and/or delivered by the feed element. The feed element is driven by a regulated electric motor disposed on the holder. To provide for yarn feeding apparatus which is both compact and inexpensive, the electric motor is a stepping motor coupled to at least one yarn feed element, which advances a yarn in a slip-free manner with its circumference, each element having its own yarn guide and monitoring devices associated with it.

    The invention relates to the knitwear industry.
    The purpose of the invention is to simplify the design of the device.
    FIG. 1 shows the yarn feeder, general view; in fig. 2 - the same, front view; in fig. 3 - the same, side view; in fig. 4 shows a device with a thread-giving drum in a deflected position, side view; in fig. 5 - thread feeding device, option; in fig. 6 is a block diagram of device control.
    The device comprises (Fig. 1) a flat holder 1, one end of which is provided with a corner 2 with mounting holes 3 made therein, the holder 1 ends with a bracket 4 with a groove 5 (Fig. 3). Using groove 5,
    the enclosing guide 6, and the clamping screw 7 fixing the device on a machine (not shown); In the groove 5 there are contacts 8 to which electric power is supplied by means of electrical leads 9.
    On the holder 1 is mounted an electric motor 10, which can be stepping or synchronous. The 1 O motor has a flange II. Using flange II and screws 12, the electric motor is mounted on the same side of the holder. , / The shaft 13 of the electric motor 10 is located perpendicular to the plane of the holder 1. On the shaft 13 there are two thread-feeding drums 1 4 mounted on different sides of the plane 15 of the holder 1. One of the Ntik arms

    from the next

    SP
    new 14 covers the body of the electric motor 10.
    The drums 14 may be made of plastic or light metal. In the drums 14 are made slit slots 16 and 17, and the slots 17 are made on the forming drums 14, and the slots 17 - in their ends. In the cavities of the drums 14 are located kinematically associated with the shaft of the engine 10 ventilation impellers 18, by means of which an air flow 19 is created, cooling the electric motor 10. For additional cooling of the electric motor 10 in the drums 14. A hole 20 can be made to which a source of compressed air is connected (not showing.
    To prevent dust and dirt from getting into the inner bands of the drums 1 4. Dust nets 21 (filter) are used.
    Each drum 14 has a cylindrical surface 22, which passes into a conical 23 at the point of its connection with the holder 1. Jumpers 24 between the slots 17 serve as the surface on which the thread 25 is wound to form turns 26. Several turns 26 are constantly located on each drum. to avoid thread spinning relative to the drum surface.
    On the holder 1, in front of each drum 14, are located the thread guides 27-29, and behind it the output thread guides 30 and 31. Each drum is equipped with 1 rotary-thread sensors mounted on the holder, which are complete as contact flexible probes: 32. and 33. For the output guide 31, there is an additional sensor for thread breakage, made in the form of a flexible probe 34 with a thread guide 35.
    1 On the holder 1 there is a color indicator 36 inside which an illuminator is installed (without showing), which is used to indicate the stop of the thread transport process.
    Mezku thread guides, 27 and 28 are located nitenate residents 37, allowing you to manually set the desired thread tension.
    The flange 11 with the electric motor Yu located on it and the drums 14 can be rotated with respect to
    14719504
    of the holder 38 around the axis 38, which has the ability to stop (a standing mechanism is not shown). For fire The sensors 39 and 40 of the extreme positions of the stepper motor 10 serve as the rest and control of the angular displacement of the flange 11. The sensors 39 and 40 are also located on the holder 1.
    On the flange 1 1, adjustable jigs 41 and 42 can be mounted, the ends of which are provided with thread guides made, for example, in the form of ejectors 43 and 44. Independent rotation of the levers 41 and 42 takes place around the axis 45, which has a stopper mechanism ( not shown). The compressed air is supplied to the ejectors 43 and 44 by means of flexible hoses 46-48.
    A kinematic connection between the shaft 13 of the electric motor 10 and the thread-supply drum 14 (drums) can be made (Fig. 5) in the form of an electromagnetic coupling 49 controlled through a conductive contact ring 50.
    A main drive 51, for example, a circular machine (Fig. 6), through Q is a gear train 52 with an adjustable gear ratio connected to a rotation angle sensor 53, which can be made electro-optical, electromagnetic, etc. Sensor 53 is electrically powered from power supply 54. The pulse output signal 55 of the sensor 53 is fed to the input of the digital Converter
    56 pulses receiving power from power supply 54. Output signal
    57 converter 56 enters the driver 58, which through amplifier 59 is connected to the input of a scapular motor 10. Electric power is supplied to driver 58 and amplifier 59 through contacts 60, which allow the driver 58 to disconnect from amplifier 59. Driver 58 and amplifier 59 are located on the printed circuit board 61, which is housed in the case of the corresponding thread guide drum 14. Elements 53, 56, 58 and 59 are the control unit of the stepper motor 10.
    The device may also have a block 62 controlling the patterning mechanism, consisting of successively turning on the block 63 specifying a pattern.

    5U
    A ditch (for example, a magnetic drum, a punched card, a punched tape) and a control vyislitelnoy machine 64, the output connected to the input of the digital converter 5-6 pulses.
    The device works as follows.
    Thread 25 passes through thread guides 27-29 and namashatsya on the conical surface 23 of the drum 14. When the drum 14 rotates, the turns 26 of the thread automatically shifts to the cylindrical surface 22 of the drum 14, From the surface 22, the thread 25 collapses and passes through the thread guides 30 and 31 , while the speed of winding the thread on the drum and descent from it are the same. The pre-tensioning of the thread provides the thread 37 resident.
    When compressed air is supplied to the hose 48, ejectors 43 and 44 are activated, the ejector 43 performing the functions of the thread brake, and the ejector 44 acting as the thread feeding mechanism. The air flowing out of the ejectors removes dust and lint from the elements of the device.
    The output frequency of rotation of the main drive 51 of the machine is reduced by gear 52 and is converted into a sequence of pulses 55. After converting the pulses 55 in the converter 56, the sequence of pulses 57 through the driver 58 and the amplifier 59 enters the input of the stepper motor 10. Thus, the rotation frequency of the shaft 13 of the stepper. motor 10 is determined by the frequency of the pulses 57. When the rotational speed of the main drive 51 changes, the speed of rotation of the shaft 13 of the engine 10 synchronously changes.
    The thread break sensors are connected to contacts 60. When the thread is broken, the contacts 60 are broken, and the power supply 54 from the power supply 54 to the driver 58 and the amplifier 59 is stopped. The stepper motor 10 and / or the drive motor of the machine stop.
    It is advisable to connect all the thread-feeding devices to the digital converter 56, since this ensures the same feed rate of the thread on all elements and stabilizes the number of turns 26
    06
    on each drum 14. In this case, the transducer 56 is filled in the form of a numeral unit.
    The latter circumstance allows the converter 56 to be used to control the patterning. Information from block 63 of task patterns goes to the permissive
    the machine 64, which, acting on the converter 56, provides the operating modes of the stepper motors 10 required for the patterning. To improve the dynamic characteristics of the stepping motors 1-0 in the starting modes, it is advisable to use the electromagnetic couplings 49. The cooling of the motors is carried out with the help of ventilating impellers
    18, while at the same time additional energy is practically not spent on engine cooling. The engines can also be cooled using a compressed air source through the opening 20.
    For convenience of servicing, the flange 11 with the 1 O motor located on it and the drums 14 can be rotated around the axis 38.
