Description of the Invention: [Technical jaw region to which the invention pertains] The present invention relates to a yarn feeding device for a knitting machine such as a flat bed knitting machine, a circular knitting machine, and the like. [Prior Art] Generally, a knitting machine (particularly a circular knitting machine) comprises a plurality of yarn feeding devices configured to feed a desired number of yarns to individual knitting positions at a desired speed. The yarn feeders are each seated on a horizontal machine ring located above the circular knitting machine. The individual yarn feeding devices are radially projecting from the ring. A yarn feeding device is disclosed in, for example, European Patent No. 0 333 482 A1. The yarn feeding device comprises a beam body, and one end of the beam body is provided with a clamp for mounting to the machine ring. The beam has a fork configuration. A distance is defined between the upper foot and the lower leg. A ball bearing is arranged on each of the upper and lower legs. A vertically arranged shaft extends through the two ball bearings. . A yarn feeding wheel is mounted on the lower end of the shaft. Between the two legs, and above the feet, the shaft supports a plurality of pulleys that are sprayed around to move to drive the drive belts of all of the yarn feeders. Alternatively, the pulleys can be coupled to the shaft by a clutch. The use of a clutch is limited by the yarn guiding member and its support. The guide yarn ' is provided with an inlet eyelet supported by a metal plate which is steeply extended upward from the lower leg portion. From the yarn entry, the thread is moved to a knot catcher and a yarn tension device (yarn tension 3 1328057 device)' which is located on the lower leg to the knitting machine. "Line movement over the delivery Sometimes, due to wear and tear, it is necessary to change the skin, and it is not possible to simply drive the belt from the top. There are no other components in that area that are more convenient for this. Because of this, when delivering and assembling a knitting machine, there are several factors that are placed on the needle and are lowered from above (for example, using a stacker == the drive belts are placed flat on the machine) Week - until the two belts are required. Then, the leather belts are: to the appropriate pulleys to replace the design of the yarn feeders of the respective worn transmission belts, European Patent No. 333 482 Α1, by Proximity to the pulley, so that it is still annoying work.,,,,:: DE 25 31 378 A1 discloses a needle (four) ❼ device 'the #' contains - the shape of the upper foot and the lower foot and A tube is not tight between the feet'. This is to arrange several belts outside the tube so that they can rotate. The scale pulley system contains magnetic elements. At the lower leg; the lower part is arranged to be non-rotatingly mounted on a rod body. The yarn feeding wheel, the rod system extends into the tube body with the heart. The rod body supports a magnet. By axially adjusting the rod body, the magnet can be coupled to different pulleys in a non-rotating manner. Above the upper foot A brake module comprising a yarn tensioning device and a yarn inlet eyelet and a yarn outlet eyelet. From there, the yarn moves downwardly to the vicinity of the yarn feeding wheel. Deflect the hook and from there to the feed pulley. In view of the above, this arrangement makes it easier to change the belt relative to the 4 1328057. However, the yarn moves past many deflection points before reaching the feed pulley. In addition, the design is also relatively complicated and makes it difficult to establish a non-rotational coupling between the rod and the pulleys by magnetic contact with the tubes connected to the legs. SUMMARY OF THE INVENTION It is desirable to provide an improved yarn feeding device. The yarn feeding device of the present invention includes a fork beam having an upper foot portion and a lower foot portion extending through a rotary support type shaft that is vertically oriented in use. In order to support the shaft, the first bearing is located on the upper leg and the second bearing is located on the lower leg. The bearings are preferably rolling bearings, for example, ball bearings. One or more of the bearings are seated on the shaft. A pulley connected to the shaft by a clutch is preferably a mechanical denture clutch. The clutches are translatable, that is, their teeth are engaged or disengaged. For this purpose, a member can be used, for example, In the manner in which the disc is axially movable on the shaft, a gripper disk for the shaft branch is designed. The clutch is preferably provided with an engaging means for maintaining the clutch in the engaged or disengaged position. At the time of starting, the engagement force of the clutch must be overcome by hand. This is particularly easy with the yarn feeding device of the invention, since the intervening space in which the component is present is completely unobstructed, in particular on the front side of the yarn feeding device. The front side is the side that is radially outward for the ring. In addition, the position of the various clutches in the yarn feeding device on the ring can be seen from a distance. On the lower end of the shaft, a yarn feed wheel is mounted to the shaft in a non-rotating manner, the yarn is wound one or more times for the wheel, and 10 5 to feed for the smaller roller. 4 Better = Yarn wheel Designed to force feed - and tilt out π. It will have a tilted entrance to a storage area, made of (__) yarn or more than one part. It is attached to the support for a splicing-hand-operated (four) screw: == same as the other one) = the beam body is worn on the knitting machine's ring. Referring to the yarn feeding device of the present invention, a yarn inlet guide device is disposed on the upper leg portion of the beam body, for example, designed to be a money-injecting eye or a yamguide pipe, but installed. It is preferred that the yarn tension is placed on the lower leg. Thus, on the one hand, the yarn entry point of the yarn feeding device is at a high point, i.e., it is disposed or fixed to the upper leg portion, however, the position of the yarn tensioning device is generally close to the yarn feeding roller. The yarn tensioning device is used to provide a uniform yarn tension to the yarn feed pulley. In this way, the necessary number of yarn deflection points and yarn guiding elements can be minimized. Referring to the present invention, there is a free space between the yarn tensioning device and the yarn guiding guide, and the yarn traverses the free intermediate space. If the yarn is removed, this intermediate space can be used to replace the worn drive belt (which is used to drive the pulley). For this reason, the yarn feeding device does not need to be removed. In particular, in order to change the belt, it is not necessary to remove the yarn guide tube provided on the yarn feeding device. However, it has been found to be advantageous to configure the kn〇t catcher to be adjacent to the feed guides (feeds and elements) on the upper legs. In this way it is ensured that the yarn will move through the slit or gap in addition to the benefit in a nearly non-contact manner. In a preferred embodiment, the 'exposed yarn delivery 1328057 feed zone is located between the knotter and the yarn tensioning device, through which the drive belt can be replaced as needed. In a preferred embodiment, the yarn guiding member and the knotter form a module unit removably attached to the upper leg of the beam. In particular, removable attachments that can be attached and detached without the use of tools are suitable. The meshing type connection between the module and the foot of the beam body is particularly suitable. The knotter can also be designed to be individually removable, as needed. Preferably, the yarn tensioning device is a modular unit that is mounted (removably preferred) to the lower portion of the beam. In this way, with the fine yarn guiding and service options (especially with regard to the replacement of the drive belt), the minimum yarn friction can be achieved, even for thin wires and at high speeds. It is preferred to completely arrange the yarn sensor (inlet stopper and yarn discharge stopper) under the device or support. Therefore, the yarn sensors do not protrude laterally from below the support. They will not stand out horizontally. The deposition of the wire ends is less likely to occur by eliminating the brackets that are laterally protruding with respect to the stopper. Moreover, these devices are extremely narrow. These devices still guarantee good access if they are mounted next to each other on the ring. Cables or components do not protrude laterally from the device and prevent maintenance and cleaning operations. Additional details of advantageous embodiments are the subject matter of the drawings, the description and the scope of the claims. In addition, the drawings are diagrammatic and supplementary to the description. [Embodiment] FIG. 1 is a view schematically showing a circular knitting machine 1. In the above, it has 7 1328057 / a ring 2 which is used as a support for a plurality of yarn feeding devices 3, and these are designed in the same manner. These yarn feeding devices 3 are guided by the machine ring. Each of the yarn feeding devices 3 is set to a speed that can be controlled to - the disc knitting machine, the human silver 4 to the example, and the yarn feeding device 3, which represents the yarn feeding device of all the clothes. The yarn feeding device 3 comprises a fork 5. The two legs, i.e., the upper leg portion 7 and the lower leg portion ,8, are the intermediate spaces or distances at which the jaws 6 extend. A bearing (better of the ball bearing 9) is disposed on the upper leg portion 7, and has a vertical rotating shaft 1G. Arranged on the lower leg portion 8 - preferably the bearing 9 - the rotation of the bearing (four) and the rotary cymbal, the bearing 9, the η system support a vertically arranged shaft 12, which is a two-turn wheel 13, 14. The pulleys 13, 14 are alternately non-dissociating: 12, dry 12 coupled. This can be achieved with a clutch 15 that is configured such that it can translate in the axial direction. The clutch can be switched with one piece (e.g., 'designed to grip circle # 15a). The disc is available at . Weekly. A spray member is provided to maintain positioning when it is in place. If the operating bell moves the gripping disc 15a by hand to shift the clutch, the operator must overcome the engaging force of the engaging member. The shaft 12 extends downwardly through the lower leg portion 8, in which case it extends through an outer casing 16 mounted to the foot portion 8 for receiving electrical and electronic components. This outer casing is composed of the same material as the clamp 5 or, preferably, is composed of a different material, for example, a transparent or translucent plastic material. The shaft 12 supports a yarn feed pulley 17 by the end from which the outer casing 16 extends. Preferably, the retractable 8<^> wire is used to "by" The attachment, the ', and the attachment screw 19 are the same. The engagement screw 19 is attached to the clamp 6 as a fixing screw. In the embodiment, the yarn feed roller 17 is a deep-drawn sheet metal member having a large taper yarn feed region 20 having a circular cross section. In addition, the 'part 2...turns to T-point storage area 21, its frame is made up, and the run-off edge of the large taper extends 22 ° when the yarn is directed to the ® disk knitting machine 1 When moving, the yarn 4 will gently pass over the edge of the ^. However, if necessary, the outflow condition (run_〇ff condition) can be adjusted in other ways. In particular, the yarn 4 can also flow out in the radial direction. In order to define the outflow condition, the yarn feeding device 3 preferably comprises at least two yarn exits 23 fixed to an arm body 25 which extends downwardly from the foot portion 8. In addition, the arm body 25 can carry a module 26 from which a pivotally supported lever 27 extends downwardly. The mold set 26 and the rod body 27 together form a yarn exit sensor capable of monitoring the presence or absence of the yarn*. For example, this can be achieved by electronically detecting the position of the rod 27. Further, the yarn feeding device 3 may include a yarn feed sensor 28 which is provided with a pivoting support type rod having a yarn guide eyelet 29 at the free end. As a result, the yarn guiding eye 29 is the only yarn guiding member located between the yarn tensioning device 30 (supported by the lower leg portion 8) and the yarn feeding roller 17. The yarn tensioning device 30 is preferably disposed on the front surface of the leg portion 8 which is not at the end of the clamp 6. For example, the yarn tensioning device consists of a ceramic pin 31 and two brake rings 32 seated thereon and which are tensioned by each other by, for example, a magnetic force. 1328057 The upper leg 7 is supported on the end face remote from the clamp 6 - the feed guide 34 (for example, designed as an entry eye 35). In addition, the upper leg ^ 7 supports a decanter 36 on the side of the foot away from the tong 6 . For example, the yoke is designed as a sheet metal member having a slit, so that the yarn 4 can ideally not It is preferred that the contact moves through the slit so as not to deviate from the yarn 4. Preferably, the knotter 36 is disposed directly below the yarn feed guide 34. The knotter 36 and the yarn guiding guide 34 are detachably coupled to the leg portion 7 independently of each other. According to Fig. 5, the engaging members 46, which can be used for the actual connection. However, the splicing member can also be designed as a module unit 33 of the shank 7. Further, the yarn guiding member 36 detachably coupled to the leg portion 7 can support the knotter (which is detachably coupled to the yarn = lead member 36). In all cases, the connection means can be an engagement device that can be manipulated without tools. An intermediate space in which no yarn guiding members are disposed is provided or formed between the knotter 36 and the yarn tensioning device 3''. The axial dimension of the one of the belts, 14 is one of: 14: the height of the drive belt 37 of the ^ Τ Μ Μ or the 传动 合 垂直 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' 4〇, the width of the branch (i.e., Fig. 2 === measurement) is the same as the width of the drive belt 37. The floor surface 40, see also = the distance between the knotter 36 and the yarn tensioning device 3〇. The second picture of the needle key 'The yarn feeding device 1 described so far is used for = parent! Don't be a circular knitting machine. The drive belt 37 is used as a drive ", the belt will wear out in the past. In order to replace, the extra 1328057 drive belt 41, 42, 43 p door, these virtual belts, pi, pi, no force. Placed on the circular knitting machine 1, if convenient, one of the belts should be placed at the bottom of l (l0 ). If the diagram of the process A reaches the yarn device 3 ^ below is according to the 3 ^ procedure. If the yarn 4 is still there, it is initially stopped, for example, between the square force devices 30 that are formed. All the yarn feeding devices 3 are placed on the pulley η by the same belt space between the yarn breaking device due to the cut or torn drive belt device, 41, and On U, as in the third continuous weaving operation. The end of the skin 4 I can be started and then transported. ^The reference device can be used on the two pulleys 13, 14 if the operator wants to set the clutch 15, for example, by the pulley 1 to the pulley 14 To drive 'this operator needs 15:^2 ^. Since the disc can be grasped from the outside by the close ... (the right side of the figure 2), it is easy to complete the action. The described yarn feeding device can include additional salient features. For example, the outer pole body: light transmissive) may include one or more indicating devices, such as a light emitting diode to indicate the reaction of the yarn feed sensor or the yarn exit sensor. Additionally, the shaft 12 can continue to extend upward beyond the upper leg 7. Here, additional pulleys can be configured. Alternatively, the upper leg portion 17 can support a motor for driving the shaft 12. Further, as shown in Fig. 4, the yarn guiding guide % can be configured as a yarn guiding tube 44. Likewise, the catheter can be connected to the module unit 33, for example, with a snap clip (Sna. chp) 45. In order to replace the belt, it is not necessary to unload this - conduit. Instead, the catheter can be left on the chat. In addition, the yarn tubes of the legs 7 and 8 are mutually slid, and the rigid connection of the detachment ensures accurate fixation. The present invention delivers an accurate guide to the yarn tensioning device. The yarn feeders optimized for protection are: === and the optimal configuration of the components such as operation and maintenance: ==== =:; and the lowest: - good = formula C - when the belt is to be replaced The following drawings illustrate a number of (4) (four) specific embodiments: Figure 1 shows a side view of a disk knitting machine in a very simplified manner; 1 is a yarn feeding device of a knitting machine; Fig. 3 is a view showing a second yarn feeding device when the driving belt is replaced; Fig. 4 is a view showing a yarn feeding method of the present invention; The figure shows a plan view of a part of the yarn feeding device.
