Definitions

  • the invention relates to an applicator of the type specified in the preamble of claim 1.
  • a leaf spring pressing a wick against the surface of the application element ensures permanent contact in the contact area, regardless of the respective height adjustment of the application element, which is height-adjustable to change the wrap angle of the thread.
  • the surface of the application element is smooth.
  • impurities such as fiber parts of the thread, dust and the like are stripped off the surface. These contaminants collect in the entry area of the contact area, to which is added the inevitable fluff flight in such applicators.
  • Impregnating agent conveyed into the contact area by the transfer member by capillary action is increasingly sucked up by the bulk, which results in an uncontrollably high consumption and the surface becomes increasingly weakly wetted and possibly dry.
  • a device for lubricating thread material in which a transfer roller running directly in a lubricating liquid bath has an arrow groove on its surface.
  • the arrow groove is used to evenly distribute the lubricant over the surface of the roll and to even out the application on the thread. Impurities and flying fluff from the thread material are introduced into the lubricant bath, which becomes very dirty in a relatively short time.
  • the thread is only impregnated intermittently due to the arrow groove.
  • a device for treating yarn with a liquid during winding and on a bobbin is known, one with the bobbin surface has rotating applicator roller in line contact.
  • a liquid container with a wick is assigned to the application roller.
  • a periodic contact between the surface of the roll and the wick is brought about by means of a drive device in order to avoid the wick becoming hot or too much liquid getting onto the roll in order to take account of the properties of the liquid and the yarn to be treated.
  • the invention has for its object to improve an applicator of the type mentioned in such a way that the consumption of the liquid impregnating agent remains essentially constant as set, there is a uniform impregnation of the thread material over a long period of operation, malfunctions due to contamination are avoided, and due to a low maintenance frequency of the applicator can be achieved.
  • the on-board cleaning device of the applicator which is active during the operation of the applicator, on the one hand removes soiling, which shows a tendency to accumulate increasingly in the contact area between the transfer member and the application element, and prevents in a preventive manner the occurrence of a disruptive one that consumes the impregnating agent Bausches.
  • the consumption of the impregnating agent remains as set and even over a long period of operation.
  • the thread is impregnated evenly.
  • a lower maintenance frequency for the applicator is possible.
  • the on-board cleaning device prevents the formation of an absorbent pad of fiber material and dirt in the contact area, because it removes contaminants in the contact area during operation of the applicator.
  • the stripping member is brought periodically to the stripping attack on the body, wherein the stripping member has the function of a driver and conveys accumulating dirt from the critical area between the body and the roller.
  • the release member serves to temporarily lift at least the body against the force of the spring pressing it against the surface of the roller, so that the contaminants adhere to the surface or, if necessary, under the influence of the wiping member , are carried away. It may be sufficient to ventilate the body only slightly or to make it largely weak so that impurities slip through.
  • the ventilator can rotate with the roller, so that it also serves as a driver and for ventilating the body.
  • the protrusion that emerges on the surface slides over the body and cleans the critical contact area. Since this occurs at least once during each revolution of the roll, an absorbent pad made of fiber material and impurities cannot arise.
  • Another embodiment is characterized in that the roller equipped with the pin or the tube is easy to manufacture and the rotating roller (either by the running thread or its own drive) provides the drive energy for the projection, which does the cleaning work carries out.
  • the edge region of a depression formed in the surface serves as the stripping member.
  • This edge area takes impurities and cleanses the body.
  • the depression causes the elastic contaminants to relax in the depression and then be carried away by the edge area.
  • the protrusion and the depression are provided, for example, essentially axially parallel on the surface of the roller.
  • Other geometric configurations or orientations can also be expedient (oblique, arrow-shaped, punctiform, etc.).
  • neither the projection nor the edge area need to extend across the entire surface; it may be sufficient to provide only sections with spacing between them. Such sections can even be offset from one another in the circumferential direction.
  • the stripping member simultaneously forms the release member.
  • the scraper member removes contaminants as a carrier and at least temporarily ventilates the body from the surface for easier removal.
  • an independent drive is provided for the air or support member in order to periodically move the member through the contact area and thereby take contaminants with it and / or to ventilate the transmission member.
  • pneumatic, electrical or electromagnetic drives can be provided which act on the body or on the spring acting on the body with suitable aids in order to prevent the temporary Airing or wiping off.
  • repelling magnetic forces are used to temporarily ventilate the body at the surface.
  • the magnet housed in the roll carries out a ventilation process with every revolution, so that the contact area is not only cleaned, but the development of the unwanted bulk is counteracted from the outset.
  • the spring is withdrawn, for example, by means of a temporarily excitable stationary magnet in order to relieve the body for a short time or to lift it off the surface so that contaminants are carried away.
  • the thread may be influenced, e.g. a pulsation of the thread tension or the thread.
  • a smooth thread contact area can be provided, in which the air or stripping element is not effective. Nevertheless, a sufficient cleaning effect is achieved because the impurities, in particular the fiber material, have a physical, mechanical cohesion, so that a wiping member that only acts in regions is sufficient to effectively remove impurities from the contact region.
  • the applicator has an on-board cleaning device which is at least periodically active during its operation and which is used to remove contaminants collected in the critical contact area between the application element and the transfer member.
  • This is expediently carried out by a scraper and / or release member rotating with the roller, which carries impurities with each revolution of the roller and, if necessary, ventilates the transfer member from the application element for easier removal.
  • the applicator can be operated with constant and precisely adjustable consumption of impregnating agent, the thread is impregnated very evenly and economically and the applicator's maintenance and refill frequency is low. It is important not to let an absorbent pad of impurities and thread material develop at all, but to preventively and periodically remove small accumulations of impurities.
  • FIG. 1 shows a vertical section of an applicator mounted on a thread delivery device, namely a thread oler
  • FIG. 9 shows a detailed front view of FIG. 1, and
  • FIG. 10 shows a detailed variant of a view similar to that of FIG. 9
  • an applicator A for applying a liquid impregnation 9, for example a thread acceptor applying paraffin oil, is mounted on the inlet side of a thread delivery device 5, which pulls a thread 2 from a thread supply (not shown) and also one not shown Textile machine, e.g. weaving machine, feeds with weft thread
  • the applicator A could also be arranged anywhere along the thread path or used for another thread processing device.
  • the thread 2 runs essentially horizontally and penetrates the applicator A under the guidance of thread sockets 14, 18
  • a rotatable application element for example a roller 1
  • a drive (not shown) (electric gear motor)
  • roller 1 being an can have substantially smooth, cylindrical surface 1 'and bilateral edge bottles 7.
  • the height of the application element can be adjusted together with the motor relative to the thread eyelets 14, 18 (indicated by dash-dotted lines; adjustment direction X) in order to change the wrap angle of the thread.
  • the drive can be an electric motor for low-voltage direct current and reversible in the direction of rotation.
  • a control circuit 4 for the drive can be contained in a housing 3, the control circuit 4 in the arrangement shown being able to be in signal connection with the drive control (not shown) of the thread delivery device 5, so that the rotational speed of the application element corresponds to the current working speed in the thread delivery device 5 is tunable.
  • a cover 20 is provided opposite to a rear wall 21. If necessary, the order element and the thread delivery device run synchronously or proportionally to one another.
  • the direction of rotation of the application element in the thread contact area can be oriented in or against the direction of conveyance (arrow). For the purpose of uniform, intensive impregnation, it is expedient to turn the application element against the thread running direction (as indicated in FIG. 1).
  • a container 19 which contains a liquid impregnating agent 19, for example paraffin oil (volume, for example 450 cc).
  • a rear wall 22 of the container 19 continues the rear wall 21 approximately.
  • a collecting funnel 8 is attached at the top, which has a passage 24 for a transfer member 6, for example a wick, a sponge, a brush, a textile strip, a capillary tube or the like, the transfer member 6 being in the impregnating agent 9 stretched in, runs up through the bushing 24 and contacts the surface 1 'under the action of an elastic force.
  • the elastic force is generated by a spring element, for example a leaf spring 10, which supports the upper end of the transmission member 6.
  • the collecting funnel 8 supports the leaf spring 10.
  • the transmission member works with capillary action.
  • a holding plate 17 for a thread brake, not shown, can be mounted on the rear wall 22.
  • the applicator A has at least one on-board cleaning device R that is active during the operation of the applicator A, in particular for impurities L deposited in the gusset at the contact area between the transfer element 6 and the application element 'Adhesive film of the impregnating agent contained dust particles, fiber components and other impurities wiped off the surface 1' by the transfer member 6 and collected.
  • the cleaning device R has a wiping member or a wiping and venting member or a venting member G which is inserted into the application element, i.e. the roller 1 is structurally integrated and with every full revolution, e.g. counterclockwise, once through the contact area, thereby slides over the transmission member 6 and temporarily releases the transmission member 6 and possibly the leaf spring 10 from the surface 1 '.
  • the link G is a rod inserted into a recess 12 in the roll 1, e.g. a pin or tube 11 (see FIG. 9) which projects with part of its outer circumference over the surface 1.
  • the contaminants L present there are carried along and removed, so that there is no longer an absorbent, larger pad of fibers and contaminants in the contact area, which increases the consumption of impregnating agent uncontrollably and greatly, and also the transfer effect the transmission link 6 would endanger.
  • the contaminants L After the contaminants L are brought out of the contact area, they fall e.g. by centrifugal force, away without being able to do any damage.
  • the rod is aligned substantially parallel to the axis of the roller 1 and inserted into the recess 12 of the roller 1 formed by a bore, expediently in a bore which also penetrates the flanges 7, the Ends of the link G, as indicated at 30, can be riveted.
  • Other methods of fastening the pin or tube 11 (clamping, pressing in, sticking) are possible.
  • the roller 1 consists, for example, of a light metal and has a polished surface 1 '.
  • the pin or the tube 11 can be made of steel With a diameter of approx. 30 mm on the surface 1 'and a diameter of the pin 11 of approx. 2.5 mm, the surface of the pin protrudes slightly more than 1 mm above the surface 1'.
  • the width of the surface 1 '' is, for example, 11 mm, while each flange can have a width of approx. 1.5 mm. It would be conceivable to provide several such links G distributed over the circumference of the surface 1.
  • a transverse rib could be formed directly in the surface this transverse rib or this projection does not necessarily have to be oriented parallel to the axis of the roller 1, but could also be oblique or arrow-shaped As in Fig. 1 round surface contour of the pin or tube 11 is not absolutely necessary, it could also be angular or out of round
  • the stripping member G is a boundary edge 13 of a depression N formed in the surface 1 ', for example a rounded groove.
  • the elastic contaminants can momentarily relax in the groove N. This relaxation is sufficient for the edge region 13 of the groove N to contain the contaminants seizes and through the contact area conveyed through and scrapes the surface of the transmission member 6.
  • the edge region 13 can expediently be rounded so that it has as little friction as possible on the thread 2.
  • a magnet arrangement is provided in the cleaning device R, which forms a release member for temporarily releasing the transfer member 6 or its leaf spring 10.
  • a permanent magnet 16 is embedded in the roll 1.
  • the leaf spring itself can form a counter magnet or carries a counter magnet 15. The two magnets are polarized in opposite directions so that they repel each other. As a result, the leaf spring 10 is briefly released during the rotation of the roller 1, so that contaminants collected in front of the contact area are carried along by the adhesion to the surface 1.
  • Dashed lines indicate that the magnet arrangement in the cleaning device R can be combined with the wiping and venting member G and / or a groove N emerging over the surface 1 according to FIG. 5. This combination not only intensifies the cleaning action, but mitigate the mechanical load on the transmission link 6.
  • a release magnet 27 is provided in the cleaning device R, which acts via a tension element 26 on an abutment 25 of the leaf spring 10 and briefly pulls it away from the surface 1 in response to a control command, so that contaminants collected in front of the contact area are attracted by the adhesion of the surface 1 ".
  • another drive mechanical, pneumatic, piezoelectric or the like
  • This device for releasing at least the leaf spring 10 can be combined with an air and / or or scraper G.
  • the cleaning device R has an air nozzle 28, for example, which directs a strong air jet or individual pulsating air jet pulses 29 into the gusset area in front of the contact area in order to force impurities L through the contact area or to briefly vent the transmission member 6.
  • the air nozzle 28 is expediently connected to a control (not shown) (solenoid valve) in order to adjust to predetermined and expediently possible, regular or irregular times to carry out a cleaning cycle. It is advantageous that the flanges 7 delimit the surface 1 'on both sides, so that the air does not escape laterally. Although a sufficient cleaning effect can be achieved with the air nozzle 28, it may be expedient to combine the air nozzle 28 with at least one wiping and / or venting element G (indicated by dashed lines).
  • a smooth thread contact area 31 is provided on the surface 1 'of the roll 1, i.e. the stripping and / or release member G is designed such that it extends only on one or on both sides of the thread contact area 31.
  • the cleaning effect which can be achieved in this way is sufficient since the impurities have an internal connection at the deposition point, so that they are effectively entrained even if they are only acted on outside the thread contact area 31.
  • a wiping and / or venting element could be provided separately from the roller 1, which is pulled periodically through the contact area by means of its own drive device during operation of the applicator and entrains contaminants.
