Description

[Technical Field] The present invention relates to a yarn feeding device for use in a knitting machine such as a circular knitting machine, such as a circular knitting machine. Knitting machine or other type of knitting machine [Prior Art] ίο 15 20 In general, such a yarn feeding device is used for a-a pre-knit machine such as a circular knitting machine; It is disclosed in the document EP() 333:A, where the yarn feeding device is designed as a bracket for the casing, which is mounted on the knitting machine in the banknote device. For this reason, = bracket (commonly known as the machine ring), on this ring, such as, · 3,, %, Zhuang, ^L, on the clothes, many of the same yarn feeding device from the machine ring Extend outward. The yarn feeding device comprises a lower arm and an upper arm, wherein the arms define a middle lower arm and an upper arm respectively supporting - for supporting - a vertical two 2 bearing, and carrying the yarn feeding wheel under the core recording arm . The pulley used to move the shaft is provided in the intermediate space between the two bearings and above the upper bearing. These pulleys are selectively engageable with the shaft. Rotating the belt drives the pulleys' to ultimately cause the yarn feed pulley to be rotated. The bracket or housing supports the yarn sensing rods with the cymbal shaft. These yarn sensing controls are located inside the housing. element. The control elements emit a yarn break signal by means of an indicator light provided on the housing. In doing so, this indicator light is located between the mounting clamp and the feed pulley. If the bystander looks at the yarn feeding device in the longitudinal direction of the casing, the bystander does not see the finger mq96064.doc 6 200837238. This perspective represents the natural orientation of the circular knitting machine as the bystander stands by the knitting machine. ",, during actual use, the yarn feeding device will become dirty. The early yarn in the air of the knitting machine or the knitted material is detached and filled with the knit workshop, and the dust is deposited on all the upwardly facing surfaces.噂, dust deposits cause unpleasant results and contain impaired function or loss of function b. Preventing this is quite important. , / ίο 15 f Η M_PS 207 940 reveals a design of a belt feeder (tape er The yarn feeder comprises a cylindrical housing, =- a bracket for one of the yarn feeding rollers disposed under the housing. The yarn is fed with a toothed disc The design is such that the drive belt feeding roller provided on the knitting machine moves to drive all the yarn feeds. The yarn is guided on the guide body (4) against the yarn guiding member between the toothed discs and thus conveyed. The chips may be deposited on the upper side of the cylindrical casing. [SUMMARY OF THE INVENTION] The purpose of the present description is to further open the yarn feeder and to obscure the disadvantages associated with one or more of the above characteristics. According to the scope of the patent application The yarn feeding device is: (4) The yarn feeding device of the present invention comprises a bracket which has a clamp at one end for mounting the 4 yarn reaching device to the textile machine. The bracket holds the two ball bearings at a distance from each other. The lead is vertically aligned. The rollers are rotatably supported by a vertically disposed shaft having a carriage at its lower end. The yarn feeder is preferably designed for active yarn feeding. This is the case where the yarn is fed without slipping. To achieve this, 7 mq96064.doc 200837238 no green is wound on the up to four turns to form a roll. When the feed is moved, the yarn is Moving through the preferably conical upper==the same day=the upper edge of the yarn feeding wheel. When doing so, the yarn is stored in the yarn = one: ft is against the lower edge of the feeding wheel At the same time, it leaves the lower edge of the 5th. The speed of the transport and reading is proportional to the moving speed of the yarn. The yarn feeding wheel can be designed as a deep-drawn steel sheet part, & ^ β, type 茏 or the like, as if :: body = part = by comparison: say 'it is held at the lower end of the shaft so that it can replace V Ίο 15 20 With screw mounting, the axial assembly screw is the same as the locking screw on the sweetness. Therefore, these screws = wheel ==: there is [: speed with the feeding pulley 7 =:: Μ 31 () 5 99 ΓΓ 动 动 特征 特征 特征 特征 譬 譬 譬 譬 譬 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据 依据The knitting machine is fixed in proportion to the knitting of at least one pulley, Tk). The column for driving the yarn feeding wheel supports the J wheel; =: the intermediate space between the pillars. These branches are of other types. Rolling bearing. The earthen structure is constructed as a ball bearing or construction. A housing defining the inner door between the inner empty pulley and the feeding pulley is preferably provided at the lowermost center and remaining under the bearing. The mq96064.doc 8 200837238 space accommodates one or more electrical components or even electronic components that can be used, for example, to monitor the operation of the yarn feeding device. The space defined by the pulley and the feed wheel is also strongly protected by the deposition of dust. On the upper side, the pulley has prevented dust deposition in the stop mode of the pulley due to its function as an umbrella and further prevents dust from being deposited in its rotation mode. On the other hand, by occupying the space between the lower pulley and the yarn feeding pulley, the casing prevents dust from being deposited on the upper side of the yarn feeding roller or in the yarn feeding pulley. For the case where the yarn feed train is preferably designed as a closed deep drawing member without a gas vent, dust deposition in the yarn feed pulley is a particularly troublesome 10 thing, so the internal space is like Canned like a jar. It also provides sufficient space to accommodate simple or even complex circuits. This can be achieved without exposing the housing to the risk of dust deposits. If necessary, the bracket can be stocked in a relatively (four) manner to reduce the amount of dust that would otherwise be harmless by retreating from the moving component and away from the yarn. ' / 20 The housing and the bracket are not absolutely necessary but are preferably designed as separate parts' which can be placed in the feed yarn i (4) when the connecting members are placed on each other. These parts can be made up of no riding. Although the bracket example = may consist of - a plastic material or a metal-mechanical stabilizer, it is necessary to take over the holding or supporting function and thus may have a different color than the bracket. This does not provide the outline of the outer ring of the machine ring and the yarn feeding device. The choice of housings and brackets with different materials also makes it possible to make the housing a whole mq96064.doc 9 200837238

On a circuit board. Furthermore, the light diode or other macroscopically visible (e.g., the housing from which the communication component can be positioned directly within the housing can exhibit light traits to enhance the visibility of the stencil on all sides. - the indicator light at the clamp and the feed pulley can be replaced. The visibility is improved. The housing can also have an antenna for transmitting and/or receiving high frequency signals. The housing and the bracket Independent design and removal of any supporting function from the housing makes it possible to design the housing with a particularly thin wall. Thus, a control element, such as a magnetically switched reed switch or the like, can be housed in the housing and The magnet placed outside is easy to operate. 15 Considering the aforementioned dust deposition, it is preferable that the cross section of the casing is slightly smaller than the largest cross section of the belt roller and is slightly larger than the upper edge of the yarn feeding wheel as needed. In this example, the diameters of the pulley, the housing and the yarn feed pulley are decreased from front to back in the stated order. ' Preferably, the yarn sensor (the yarn side stopper and the yarn exit side yarn stop) 20) full female I in the device or bracket Under the main body, therefore, the yarn sensor does not extend laterally from the bottom of the bracket body. Because the side-extending bracket of one part of the yarn feeder is eliminated, the dander is difficult to deposit. Moreover, the design of the device is very small. Even if they are mounted next to each other on a machine ring, they still permit good access to the device. During maintenance and cleaning operations, there are no interference lines or other components that protrude laterally from the device 10 mq96064.doc 200837238. Further details of the advantageous embodiments are the subject matter of the drawings, the description of the embodiments, and the claims of the claims.

Preferably, the locking screw cup 19 is identical to the locking screw 5 to assist in a simple and reasonable handling of the yarn feeding device j. 5 10 15 20 is a part of the lower pillar 9 'The device can extend into the belt: inside the workshop. Although the pulley 16 is positioned under this condition, the gap between the garment 7 and the bearing means 6 or the internal space extends at least partially above the lower bearing means 7. The set 7 is preferably a portion of the post 9 below the bracket 3. The struts 9 of the struts extend to an end 2 〇 on which a yarn tensioning device 21 can be placed. The yarn stretching device can be any conventionally known: a ring that adheres to each other by magnetic force, whereby the 'yarn= must pass between the rings. To guide the yarn 22 along its path to the yarn drawing device 21, a feed loop eye 23 on one end can be provided. This strut 8 extends, for example, to the bean device 2 and extends to the bearing device 6 and then extends from the bearing device 6 = H24. Under the yarn loop 23, a knot remover 25 is provided, which is constructed as a metal sheet member having a slit, thereby making a 25"_two two=removal device (knot wheel 16 from "^, Between the Quanla County, the gap allows the belt example 'τ leg 9 to better support a casing * ΓΓΪ between the lower pulley 16 and the yarn feeding pulley 15 if the yarn feeding wheel 15 The diameter and the diameter of the pulley 16 are mutually mutually mq96064.doc 12 5 10 15 20 200837238 When, the intermediate space is cylindrical. If the diameter of the yarn feeding pulley 15 is small, the diameter of the Z wheel 16 is slightly smaller. Thin and smaller in the downward direction. In this case, the shape of the clamshell 26 is preferably determined in such a manner that the interstic space is substantially filled. Obviously, the pulley 16 and the shell are specifically described. The body 26 and the feed pulley 15 are offset from the top (10) main section by a diameter transverse to the struts 9 (measured perpendicular to the projection plane in Fig. 1).

20 During the operation, gross money may deposit on the bracket 3, but not above the casing between the pulley 16 and the yarn feeding device 15. Despite the ‘phase: large volume and large internal space, the housing keeps the shovel on the outside. The transparent exterior is still clean' as in the case of the example embodiment: the indicator light in the private space remains visible from either side. Due to the higher cleanliness of the device and better visibility of the indicator light, the salty device is more acceptable to the end user. With reference to the yarn feed device i, there are many variations that are feasible. For example, as shown in Fig. 4, the bracket can be provided between the legs 8, 9 by a strip 49 to strengthen the recess 80 between the strip 49 and the clamp 4. This pocket mq96064.doc 15 200837238 ϋ _ can be, (four). The latter is of particular interest in the manufacture of plastic materials with brackets that are cost-effective. It can be said that if there is a figure = the housing 26 is deviated from the cylindrical pattern. For example, Figure 5 shows the shape, that is, has a polygonal cross section. Corresponding edges 51, 52, 53, 54 of the housing 26. = Also ▲ has a cross section of a human shape or a different shape. However, it is possible to modify it in ancient times. For example, as shown in Figure 5, the support 3 is open configuration. The separation may, for example, affect the lower strut: = circuit board 41, extension 42 and support the yarn feel: torque 8 is connected to: ::: 5 to - no 15 relative to the axis of rotation 13 The housing of Fig. 5 can have a full or partial conical shape, and the housing can have a slight extension beyond the upper edge of the feed pulley 15, and a tapered lower edge 56' to protect the wheel and its interior space.

In accordance with the teachings of the present invention, it would be particularly advantageous if the yarn feed pulley 1 permits a modular construction. The yarn exit side yarn stopper composed of the yarn take-up sensor 45 and the yarn exit loops 47, 48 and other = parts represents a detachable yarn feeding device without removing the yarn feeding device from the machine ring. Assembly. The same applies to the feed pulley 15 and the housing 26 with the electronic system therein. Therefore, this new yarn feeding device 1 mq96〇64.doc 16 200837238 is particularly easy to maintain. Figure 6 is a schematic illustration of a modified embodiment of yarn feed sensor 44. The yarn feed sensor 44 is arranged to pivot about the horizontal axis of rotation 57. The internal space 29 + ancient a ^, 5 10 of the casing 26 has a dry opening 37 which is prepared as a magnetic sensor. In the open-close-installed non-movable permanent magnet 58 open == the detector 44 is connected to the -metal (four), the metal cover in the yarn 22 is located between the permanent magnet 58 and the reed switch 37 . This cover isolates the magnetic field of the cough permanent magnet from the reed „37. This is an open circuit and also does not conduct current. If the yarn is loose or broken, the yarn sensor moves to another position, thus the metal cover 59 moves away from the middle switch between the permanent magnet 58 and the reed switch 37. At this time, the magnetic field of the permanent magnet 58 reaches the dry _ 37. The contact of the switch is closed; the current can flow. The same principle can be applied.
