Field of the Invention The present invention relates to a yarn feeding device for feeding a yarn to a circular knitting machine, particularly a circular knitting machine having a yarn changing device and a circular jacquard knitting machine. [Prior Art] The prior art documents in the field are known, for example, in Japanese Patent Application Laid-Open No. Hei. No. Hei. No. Hei. The yarn supply is particularly suitable for a circular knitting machine having a yarn converting device (changing device) for supplying a multi-color yarn to a knitting machine as needed. In general, the belt-driven yarn feeding device used in the circular knitting machines is provided with an endless (annular) belt that travels through a plurality of driving wheels, which are usually used together with the knitting machine during the operation of the knitting machine. The yarn feeding wheel that is driven integrally with the driving wheel driven by the endless belt is covered by a stretchable resin tape such as a rubber belt having a friction surface having a large frictional force. . A fixed yarn guide having an introduction hole and a lead-out hole at each of the yarn inlet side and the yarn outlet side is disposed adjacent to the yarn feeding wheel, and a yarn guiding hole having a guiding yarn at the front end and can be fed along the above The movable yarn guide of the circular motion of the surface of the yarn wheel is in the opposite position of the two. The movable yarn guide is provided with an elastic device for driving the movable yarn guide to move along the surface of the yarn feeding wheel to reduce the contact angle of the yarn to the non-feeding state, and the circular knitting machine The tension-force of the yarn selected by the yarn changing device produces an elastic force greater than that of the elastic means, forcing the movable yarn guide to move to the -feed state. The yarn is fed into the knitting machine at a speed substantially the same as the peripheral speed of the surface of the yarn feeding wheel by the frictional force of the rubber belt on the surface of the yarn feeding wheel. 201043743 [Problems to be Solved by the Invention] When the above-described conventional device is used in a circular knitting machine including a yarn changing device, the movable yarn guide moves to a reduced yarn when the yarn is stopped. The non-feeding state of the contact angle is only a conventional device in which the yarn does not completely leave the surface of the yarn feeding wheel and still has a part of contact, and the contact yarn sometimes entangles due to friction with the friction surface of the yarn feeding wheel. The friction surface of the yarn feeding wheel or the yarn breakage due to friction. Moreover, when used in a jacquard knitting machine, the amount of yarn required by the knitting machine required to match the pattern may be different from the amount of yarn fed from the yarn feeding device, and the yarn may be loosely entangled in the friction surface of the yarn feeding wheel. The situation happened. As a result, the yield of the knitting machine is reduced or the quality of the woven fabric is lowered. Further, in the form of Japanese Patent Publication No. 61-47777, in order to prevent the yarn from being displaced to the non-feeding position without contacting the yarn guiding surface, the distance from the fulcrum of the yarn guiding device to the yarn guiding hole must be lengthened. In the lateral space in which the yarn feeding device is disposed, it is necessary to be wider, and in addition, the yarn guiding device is not long enough to achieve a rapid reaction. (Scheme for solving the above problems) The yarn feeding device of the circular knitting machine of the present invention is composed of at least one yarn feeding wheel, a fixed yarn guide disposed adjacent to the yarn feeding wheel, at least two movable yarn guides, and The fixed yarn guide has a lead-in hole on the yarn inlet side and a lead-out hole on the yarn outlet side; the movable yarn guide is a first movable yarn guide and a first a movable guide having a yarn guiding hole for guiding the yarn to the front end, and the surface of the yarn feeding wheel is centered on a rocking axis which is located away from a central axis of the yarn feeding device Row arc motion; characterized in that: the first movable yarn guide has a vibrating circular motion of the 201043743 one rocking member, and the second movable yarn guide has a second rocking member capable of circular motion; the first rocking The member is provided with a first elastic member capable of forming a resistance force of the yarn feeding tension of the yarn, and the second shaking member is provided with a second elastic member capable of forming a resistance force of the yarn feeding tension of the yarn. Preferably, the lower seat and the second rocking member are coupled by the second elastic member, and the second rocking member and the first rocking member are coupled by the second shaft and the first elastic member. . Preferably, the second movable guide is configured to move in a direction of travel of the yarn with a weaker force than the first movable guide, in other words, by a second elasticity corresponding to the second movable guide. And a resistance force of the member forcing the second movable guide to move toward the traveling direction of the reverse yarn is set to force the first movable guide by the first elastic member corresponding to the first movable guide The tendency of the yarn to move toward the direction of travel of the reverse yarn is weak. More preferably, the second elastic member and the first elastic member are configured to provide at least one of the following functions (a) to (e): (a) when the yarn feeding device is in a non-feeding state, The first movable guide is passed through the introduction hole, and the second movable guide and the yarn passing line of the lead-out hole are kept from contacting the yarn guide surface. (b) urging the force of the movement of the second movable yarn guide in the traveling direction of the yarn by the yarn feeding tension of the yarn passing through the yarn guiding hole to be large (strong) by the second elastic member And forcing the second movable guide to move the resistance force to the traveling direction of the reverse yarn, the second movable guide is separated from the first movable guide: the yarn feeder while keeping the interval therebetween The yarn state moves to the initial state. (c) after the second movable guide reaches the position of the yarn feeding state, the movement of the first movable guide to the yarn is promoted by the yarn feeding tension of the yarn of the above-mentioned yarn guide hole by 5 201043743 When the force of the directional movement becomes large (strong) by the first elastic member corresponding to the first moving guide, the first y === resistance force is caused by the above-mentioned first, the guide yarn - (4) When the yarn feeding tension of the yarn passing through the yarn guiding hole causes the force of the twister to move toward the traveling direction of the yarn to become small (weak), the movable movable guide corresponds to the first elastic member. When the above-mentioned resistance force of the movable yarn guide moving in the traveling direction of the reverse yarn is caused, only the above-mentioned movable yarn guide moves from the yarn feeding state to the starting state. (e) urging the above-mentioned yarn by the yarn feeding tension of the yarn passing through the yarn guiding hole: the force of the moving yarn guide moving in the traveling direction of the yarn becomes small (weak) = and the second When the movable guide (4) corresponds to the second elastic member to urge the first movable guide (4) to move in the traveling direction of the reverse yarn, the movable guide is maintained with the first movable guide Its spacing - from the side to the non-feeding position. The elastic force of the second elastic member and/or the first elastic member is adjusted by the elastic adjusting device. The elastic force adjusting device can be arbitrarily selected from the plurality of pins on the base, and the end position of the second elastic member can be changed or can be arbitrarily selected from the base. A plurality of holes and a rocking arm that can be inserted into the protrusion of the hole are combined. In the above, the plate spring is formed, and the protrusion is pushed into the hole by the spring force. X, the elastic force adjusting device is not limited to the above configuration, and the mechanism for forming the 201043743 rocker arm to be freely stopped within the moving range of the rocker arm may be used. Further, it is preferable that the above apparatus is provided with means for restricting the arcuate movement angle between the second rocking member and the first rocking member. The means for restricting the arcuate movement angle between the two may be, for example, a combination of a pin disposed on one side and a linkage groove provided in one of the two, and serving as a positioning member of either of the second rocking member and the first rocking member. Preferably, the device is further provided with a stopper for restricting the circular arc motion of the movable guide for limiting the range of movement of the first movable guide and the second movable guide. The stopper may be formed, for example, by a vertical wall that abuts the second movable guide and an arc-shaped holding portion that is disposed above the vertical portion, and the feeding device is provided with a casing Corresponding to the arcuate groove of the holding portion, the vertical portion is held to be linearly movable along the circumferential surface of the yarn feeding wheel. More preferably, the stopper is provided with an adjustment mechanism that adjusts the contact range of the yarn feeding wheel depending on the type of the yarn. The adjustment mechanism may be formed, for example, by a plurality of notches provided in the holding portion, a ball corresponding to the notch provided on the casing, and a hole provided with a spring and a screw provided in the upper portion of the ball. In another configuration, the first rocking member may be omitted from the first movable yarn guide, and the first movable yarn guide itself may be replaced by a single leaf spring. According to the present invention, the first movable guide and the second movable guide may be interlocked with each other along the yarn introduction hole and the lead-out hole around the yarn guiding surface. In addition, the first movable yarn guide and the second movable yarn guide 7 201043743 can increase or decrease the yarn feeding tension according to the required knitting pattern, move the angle of the yarn guiding surface to the yarn feeding position, or make the above guide The increased contact angle of the yarn of the yarn surface is reduced to the non-feeding position. When the yarn is at the position of the yarn, the woven yarn of the movable guide yarn 15 and the upper discharge hole which are contacted from the introduction hole through the first movable yarn guide can be kept in a state of no surface, and therefore, the yarn is not entangled. Occurs on the friction surface of the yarn feeding wheel or yarn breakage due to friction. From the non-"position (4) to the yarn feeding position 'with the increase of the yarn feeding tension, the second movable yarn guide will move toward the above-mentioned lead-out hole, and the first movable body in conjunction with the first movable yarn guide The yarn guide is moved as it approaches, and while the side is held in the non-feeding position, the first ΙΓ(4).-side (four) the above-mentioned μ hole is moved close, so ί face:=the loose one produces 'and not Friction with yarn delivery After the second movable guide moves to the maximum position, the first movable guide moves to the maximum position, and the angle of the yarn is The yarn guide surface becomes the largest. / When used in woven flowers whose yarn quantity changes, since the yarn is loaded by a plurality of yarn guides = the length of the yarn is not loosened so that it is entangled in the friction surface of the yarn feeding wheel.

The resistance of the first-movable yarn guides 16, 116 to the direction of the reverse yarn is large == =: basically and the actual (the efficacy confirmation experiment) page to the third page) Let me repeat. v-LE==(4) The electronic jacquard knitting machine with thread adjusting device made of long fiber, and the following is the G test! 8 gauge (regulation), "Silk coffee belly, stop state - because the movable yarn guide keeps the tension of the yarn moving. 15 201043743, that is, no excess yarn is produced, so there is no yarn. The situation of entanglement with the friction surface of the yarn feeding wheel occurs. [Table 1] Number of times of 36. lcmxl 1.4 m woven fabric entangled on the friction surface of the yarn feeding wheel. Conventional technique X Example 1 〇 Example 2 〇〇: 0 times Δ: 10 times or less X: 10 times or more b When used for stripe weaving, the condition when the yarn is stopped is shown in Table 2. Since the yarn is completely out of contact with the surface of the yarn feeding wheel, there is no yarn entangled in the friction surface of the yarn feeding wheel and friction. The situation of yarn breakage occurs. [Table 2] The number of times of friction - 1.4 m woven fabric entangled in the friction surface of the yarn feeding wheel per suffix - 3 m times, entanglement yarn breakage - 1 yarn breakage - 2 Conventional technique X 〇 Δ Example 1 Example 2 〇〇〇〇: 0 times Δ: 10 times or less X: 10 times or more Note: The above yarn breaking-2 test uses 40 yarns of cotton yarn. c) The situation used for jacquard weave is shown in Table 3. Because the yarn tension is imparted by many yarn guides, the yarn 16 201043743 line does not slack, and the yarn is entangled in the friction of the yarn. The situation happens. [Table 3] Number of times of the 36. lcmxll.4m woven fabric entangled on the friction surface of the yarn feeding wheel. Conventional Example 1 〇 Example 2 〇〇: 0 times, Δ: 10 times or less X: 10 times or more From the above experimental results, it can be seen that according to the present invention, the working efficiency and the weaving quality of the knitting machine can be improved, and the lateral installation space required for the yarn feeding device to be mounted on the circular knitting machine is the same as that of the conventional device.
