Definitions

  • the invention relates to yarn feeding apparatus which serves to supply yarn to a textile machine, such as a knitting machine, a knitting machine, a loom or other thread-receiving machine.
  • the thread monitor may include detecting its tension or merely limiting itself to determining whether the thread is present or not, or whether it is reasonably taut or sagging beyond a certain extent.
  • Serve so-called yarn feeler for example, as separate units or devices or as Component of other textile-technical devices, such as yarn feeding devices, are available.
  • the DE 84 29 344 U1 a yarn error detector in the form of a pivotally mounted two-armed lever.
  • a lever arm carries at its end a thread eyelet through which the thread to be monitored is running.
  • the other lever arm carries at its end a permanent magnet, which is associated with a Schutzrohrheftschalter.
  • the lever arm pivots away from the thermowell contact switch, its contacts open and a circuit is broken. If it turns towards the protective tube contact switch, it closes and a circuit is closed.
  • the pivoting of the lever arm is effected by the thread passing through the eyelets at the other end of the lever arm.
  • the lever arm and the protective tube contact switch are arranged inside a housing, which also houses a locking device for the yarn detector.
  • the locking device has a pivot lever which projects through a housing slot to the outside. Through this housing slot dust can get into the housing interior, which can lead to long-term malfunction.
  • Another device for thread monitoring is from the DE 32 24 960 A1 known.
  • To this device includes a pivotally mounted lever which is movable by the thread.
  • Two levers are connected to the lever which carry permanent magnets for actuating protective tube contacts. Depending on the deflection of the lever closes one or the other contact, so that an electric motor is reversible in its direction of rotation.
  • the DE 42 066 07 A1 discloses a yarn feeding device with yarn supply drum, which is driven by an electric motor.
  • This device has both a yarn breakage sensor and a yarn tension sensor.
  • the thread breakage sensor consists of a pivotally mounted lever, which is externally attached to the housing of the device. The lever is mounted on a housing bushing and rotates a magnet mounted in the housing. This in turn influences a protective tube contact.
  • a resilient tube in the form of a trumpet-shaped coil spring wound, which is attached at one end to a turntable. This is supported by a shaft which projects through the housing and interacts with a sensor inside the housing.
  • the housing bushings allow long-term penetration of dust into the housing.
  • the GB 2174415 A describes a yarn feeler whose Fadenfühlarm is element of a magnetic circuit with a coil.
  • the arm is resiliently attached to a housing with a screw. There is only a small gap between the arm and the housing.
  • a thread monitor is known, which causes a change in a force acting on a switching contact magnetic field by changing the position.
  • the thread monitor is rotatably mounted on an axle and carries at its other end a permanent magnet as a switching contact.
  • the other end of the thread monitor which is connected to this at right angles to the axis of rotation carries a serving as a donor magnets.
  • the GB 2 033 435 A describes another thread monitor. Also in this about an axis rotatable thread monitor a lever is designed as a thread monitor and forms the angle to the other arranged lever a donor.
  • a sensor device monitoring the position of the yarn feeler consists of at least one transmitter element and at least one sensor element which interact with one another.
  • the transmitter element is connected to the yarn feeler, while the sensor element is arranged inside the housing.
  • the transmitter element can be regarded as a signaling element that signals its position.
  • the sensor element can be regarded as a detection element which detects the position of the signaling element.
  • the yarn feeler and the donor element are arranged outside the housing, which can thus be formed completely closed.
  • the penetration of dust and river, which is otherwise a major problem, is thus prevented.
  • restrictions on the freedom of movement of the yarn feeler, contact difficulties, contamination of contact points and blocking of switching elements can be effectively avoided.
  • the storage of the yarn feeler is arranged outside the interior of the housing. This results in a simple and easy-to-assemble device construction. Overall, a high reliability of the device is achieved.
  • the device described so far may be a separate thread sensor or part of another device, such as a yarn feeding device. It may be a device for detecting the thread tension or merely for detecting the presence of the thread, such as a yarn breakage sensor act.
  • the invention is applied to a yarn feeding device, which is used for quantity-controlled or tension-controlled yarn delivery.
  • the first mentioned devices are also called positive feeders. They have, for example, a carrier designed as a housing, which has at one end a fastening device for attachment to, for example, a knitting machine. The carrier or the housing are penetrated by a rotatably mounted shaft, either by an electric motor or is driven by a pulley ago.
  • a yarn feed wheel is attached, which is looped by the thread to be supplied. By rotation of the yarn feed wheel, the thread is conveyed.
  • a yarn feeler is arranged, which may have, for example, a pivotally mounted lever.
  • the lever is loaded by its own weight on the thread.
  • the yarn feed wheel is preferably removable on its shaft and thus kept interchangeable.

  • a Fadenauslaufbaum be present in order to regulate with an adjusting movement at the same time also the angle at which the thread leaves the yarn feed wheel.
  • the sensor device is a switching device which monitors whether the yarn feeler is above or below a switching limit.
  • the thread sensor carries a donor element for this purpose. This is an element whose position can be monitored by the sensor element out of the housing interior, while the transmitter element is arranged outside of the housing interior.
  • the housing is made of a non-magnetic material.
  • This can be in particular plastic and allows the monitoring of the position of the yarn feeler by means of a magnetic or electromagnetic field.
  • the housing is formed nonmagnetic where sensor element and the transmitter element interact.
  • the housing as a whole consists of a non-magnetic material, such as plastic.
  • the yarn feeler element is mounted on a bearing device, which allows a pivoting movement of the yarn feeler element.
  • This bearing device is arranged outside the interior of the housing. It can be formed for example by bearing openings in the form of blind holes in the housing wall or bearing openings, which pass through a housing projection, without having a connection to the interior of the housing.
  • a portion of the yarn feeler can move in the bearing opening with play. This contributes to a leichcoven storage, which is little prone to contamination. In particular, however, no dirt particles can pass through the bearing opening into the housing interior.
  • the yarn feeler preferably carries a donor element or is itself the donor element.
  • the donor element may for example be a permanent magnet, a soft magnetic part, for example of ferrite or a ferromagnetic metal, or another metal part.

  • the magnet may be made of a plastic material. For this purpose, for example, elastomers filled with magnetic fillers materials on the market that are processed, for example, in plastic injection molding or supplied as rubber bands, which are necessary to cut with simple tools.
  • a soft magnetic encoder element can serve to change a magnetic field, the magnetic field change being detected by the sensor element arranged in the interior of the housing.
  • the soft magnetic part can influence the magnetic flux that passes through a protective tube contact.
  • the sensor element in these cases is an element that detects a change in the otherwise static magnetic field.

  • yarn sensors in the form of a yarn inlet sensor 26 and a yarn outlet sensor 27 can be provided.
  • the yarn inlet sensor 26 and the yarn outlet sensor 27 are each used to distinguish whether thread is present and does not sag too much, and to generate from this a corresponding electrical signal.
  • both yarn feelers each have a lever 28, 29 designed, for example, as a wire bow, which can be designed as one or two-legged as shown.
  • Fig. 2 each formed as a U-shaped wire bracket whose lower, preferably straight web 30, 31 rests on the thread 15.

In this case, the ends of the contact tongues 48, 50 abut each other (ie they form a "normally closed contact"), while between the ends of the contact tongues 49, 50 there is a gap (ie they form a "working contact”). While the contact tongue 48 is non-magnetic, the contact tongues 49, 50 are soft magnetic. A sufficiently strong magnetic field therefore causes the contact tongues 49, 50 to attract and abut each other while the contact tongues 48, 50 separate.
