Right 9 ^ y- λ /, λα- ^ There are two kinds of' Figure 1, Figure. Stick 12 or free 13 on the side of the bobbin i or t, ^ As shown in Figure 3, orthodox 16 is wrapped around the fine end of the bobbin ^ bobbin ^ will be far from the end of the bobbin ^, One or more yarn loops 17 are generally the best with 2 to 3 loops. The ν loop 17 is untied or torn off, as shown in Figure 1 or Figure 2. When entering the winding project, it can be summarized into three steps for cyclic processing, 2 steps of yarn, yarn search head and winding, which cut a large amount of the above-mentioned fine official yarn 1 before being collected in the yarn collection room for automatic conveyance. Set the operation, and then enter the cyclic conveying belt one by one and continue the conveyance at a single and constant speed, and then enter the yarn end step in sequence. The yarn end step can be subdivided into three steps. Yarn loop 17, second, release cloth stick type yarn head 12 and as shown in FIG. 4, third, find the yarn head to hold and stretch a length of 18, and suck it into the hollow space 100 of the exit end 15 of the yarn tube 11 . As shown in FIG. 5 ′, the method of unwinding the loop 17 in the first step is to provide a friction at a proper distance beside the tail 16 side of the thin 1 to rotate the bobbin 1 in a direction opposite to the winding direction of the loop 17. The wheel 2 uses the friction to drive the spun bobbin 1 to rotate, and disengages the winding yarn loop 17 into the cloth type 12 as shown in FIG. 1 or the free type 13 as shown in FIG. 2. Generally, it is shown as the cloth type 12 as shown in FIG. 1. 'Most of them are due to static electricity, but the cloth type will still cause the trouble of the low success rate of the yarn head. The free type 13 is the best. It is how the friction wheel 2 reverses, approaches and rubs to the end 16 The mechanism of disassembling the winding yarn loop 17 is a conventional technology and is not a technical range explored and improved in this case. It is only shown in a simple diagram here. In order to ensure the free form 13, it will enter the second step. The process of the yarn end 12, as shown in FIG. 6, is provided with a yarn picker 3 at an appropriate distance from the side of the thin tube yarn i. Generally, it has a lever 30 which can be moved up and down, and the lever 30 can be displaced. A slight distance from the tube body, and it moves up and down, can loosen the cloth-attached yarn head 12 loosely, causing How the transmission of the shift lever 30 moves a minute distance from the tube body and up and down displacement, its mechanism is not the improved technical range of this case. It is still only shown in the figure below. After the end of the process, finally enter the third step, find the yarn head to hold and stretch a length of 18 and suck into the hollow 100 of the tube U exit end 15 of the process, as shown in Figure 7, tied to the spinning tube The top end 101 of the yarn 1 is provided at an appropriate distance. An air hood 4 which can be expanded, contracted, and retracted is provided. The air hood 4 is connected with an air suction pipe 40. The air suction pipe 40 has a proper length and is at its tail end 40. 〇A yarn breakr μ is provided, and a blower tube 42 is also provided adjacent to the top of the wind hood 4. When the yarn head enters the free-form 13 bobbin and is located directly below the wind hood 4, the wind The hood & can be pulled down and covered with the tube yarn 丨 by the suction of the suction pipe 40, the yarn head is held and brought to the tail end of the suction pipe 400, and the yarn cutter 41 It is cut into a fixed preset length 18, at this time the suction pipe 40 stops suction, and the blower pipe 42 starts to the yarn exit 15 of the spun yarn tube. The hollow part of the tube is 100 high pressure air blowing. Please refer to Figure 4 again. Then, the spinning head of appropriate length 18 in this section will be brought into the hollow part 100 of the tube by the high-pressure airflow to complete the pre-winding operation of the winder. How and when the air hood 4 is pulled down, the structure of the suction pipe 40 is used to hold the suction, and the structure of the blower pipe 42 is used to control the blowing. The details of the mechanism are also known. It ’s still just a simple tone chart! 231323 ^ Cheng said that the hollow end 1 of the conventional yarn exit u of the fine yarn tube u is smooth. There is no grip point at all, so this section of yarn of appropriate length 8 ”疋The free type is indwelling in the hollow 100 in the tube, and because of the elasticity and flexibility of this elastic yarn, the appropriate length of the yarn T 1? Is not straight, but purple. Shape, and sometimes even worse, it can be curved to form a 坨 -shape, and it is adjacent to the end 101 H of the hollow 100 in the tube, so in the conveying movement after the third step of the yarn-finding step described above, again Yada length I curve or the yarn head 18 with a shape of ± will be bounced out of the tube again, and the chance of being at 100 Quite high, the way to overcome this lack is known, 疋 will retain the appropriate length yarn head 18 with 2 times the length required for non-elastic yarn to prevent the length after I curved is not enough to stay in the hollow of the tube ⑽, However, the elasticity of ± | and the excellent flexibility can be left in the hollow of the tube_, because it is close to the end 胄 1G1 at S = 中 玉 处 〇〇, so it was slammed and ran out to 7 s The probability outside 11 is still quite high. According to the field inspection, the probability is 8 15 wheat. "When entering the winder, as shown in Figure 8, the holding arm 5 of the automatic winder 5 will Swing down and touch the exit end of the spinning tube 15, and hold the spinning head of m and the appropriate length 18, and bring it up to the knotter η. Only after the b is hit, the winding is successfully continued by the roller 52. When the holding arm 5 " Go not, Xitou ', then the holding arm of the 5 Hai automatic winder will be fixed for 20 times before the machine will try again a predetermined number of times before the hem suction job fails. The spun bobbin 1 is dropped back to the conveyor belt, and then brought back to the yarn end step again, until the winder 5 is held to the yarn end and the yarn is finished. If there is a break in the winder, Situation will occur 1% chucking arm attempts predetermined number of times and failed the yarn end suction skirt 4 after spinning cop! The top of the conveyor belt is taken back and then re-doing the first step of finding yarn 1231323. The same way, how can the holding arm 50 hem, suction and return to the original position, what mechanism the machine uses to find the yarn at the end of the package yarn The head and how to knot the knotter 51 are also known techniques and are not the technical scope of the investigation and improvement of this case. They are still only shown in a simple schematic diagram, and the spun bobbin 丨 such as 5 is ejected back to the conveyor belt. It is also known and omitted. The above-mentioned shortcomings can be summarized as: 丨 · The yarn end of the elastic yarn cannot be held by the winder as the yarn winding. It is not possible to ensure the quality of the winding and to carefully cover the yarn 1 in the winding machine. Returning and causing a high percentage of idling of the machine will not only waste energy, but also reduce production capacity; 2. Long yarn retaining heads will be cut into ^ parts which will be cut off after knotting, resulting in raw materials (spinning). Waste; therefore, how to conceive an elastic yarn end of a spun bobbin can be surely held by the yarn holder and the preparation machine to make the yarn winding, to ensure the quality of the winding and to avoid it The spinning bobbin was returned repeatedly, causing a high percentage of idle 15 revolutions of the machine, which can increase the production capacity and save energy, which is an important issue. [Summary of the invention] ^ The main purpose of the present invention is to provide a yarn b that makes a spun bobbin elastic. The yarn b is surely held by the winder as a knot winder, so as to ensure the winding. In the winding project, the yarn bobbin was repeatedly returned, resulting in a machine with a high percentage of idling, which can increase the productivity and save energy. The present monthly card holder is tied in a plug body, and one or more card slots are provided in the longitudinal direction. The effect of the present invention can provide _ a kind that can ensure the quality of the winder and avoid the spinning of the yarn in the package ^, which will result in a high percentage of idling of the machine, which can increase productivity and save energy. 1231323 [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the following detailed description with reference to the second preferred embodiment of the accompanying drawings. 5 10 15 Referring to FIG. 9 and FIG. 10, an embodiment of the yarn clamping device 6 of the present invention is housed in a plug body 60, and one or more card grooves 7 are provided in the longitudinal direction of the plug body 60. More specifically, In other words, the plug body 60 can be made of a plastic material, and the formation of the card slot 7 is made of the plug body 60 with a plurality of baffles protruding radially from the inner peripheral wall 610 of a ring pipe 61 toward the center. 62. There are six in this embodiment, and the free end edge 620 of each side of each baffle 62 is near the center of the plug body, and there is a proper distance from the center of the plug body. Therefore, the first card slot 70 is formed. The groove 70 is straight. The first slot 71 in the figure is funnel-shaped. The shape of the funnel is due to the width w of each baffle 63, which is formed by narrow and wide molding from the top 63 to the bottom 631. ' The funnel-shaped first slot 71 is easier to enter than using a straight head, because the entrance is wider. In addition, the broadcast films 62 and 63 in FIG. 10 and FIG. 11 each have a first slot. The two card slots 72 and 73 are respectively communicated with the first card slots 70 and 71 of the card slot. The card, y, and device 6 are set at the tube of the yarn exit end of the yarn bobbin 1 at the position of $ 1. When used, when the yarn end 18 of the above-mentioned appropriate length is used by the first-type card slot 70 or The funnel-shaped first card slot 71 is curved; more so—the material, such as ® 1 1 will block and jam in it-the second card 4 has a bottom 730,-like this, it will be blocked as Most often, or: = is stuck at the longitudinal bottom of the baffle 62 or baffle 63, or at least jams; is at the bottom of the -th card slot or-71 slot, or is stuck in the second _ 20 1231323 In the first or the third card slot 73, or the first card slot 70, the first card machine 5, and the many card jam chances are caused, the holding arm 50 of the full-automatic winder as shown in FIG. 8 hems down When it nearly touches the exit end of the yarn bobbin at 15 ^ Baobaidaobai can suck the yarn head 18, and bring it up to the knotter 5 1 for 5 knots, the household weight Zx, σ will not idle. When looking for the yarn end, the spun yarn 1 will never be ejected back to the conveyor belt to find the yarn end again, which can save energy and greatly increase production capacity and ensure the quality of the winding. The invention described above can ensure that the yarn end 18 of the appropriate length is sucked into the hollow space e at 100, and the yarn end or the yarn end that is curled must be caught in the yarn holder 6 , So that each yarn suction head of the automatic winder 5 can be sucked in one stroke, and the appropriate length of the section does not need to be set too long, it will not cause waste of raw materials, and can increase productivity, winding quality, and Avoid high-probability idling and wasting energy. However, the above are only the preferred embodiments of the present invention. If [5 can be used to limit the scope of the present invention, that is, a simple equivalent change made in accordance with the scope of the patent application and the content of the invention specification And modifications should still fall within the scope of the invention patent. 20 10 ^ U23 [Simplified description of 囷 style] Figure 1 is a schematic diagram of spinning and finishing;, :: perspective view of the first form of worsted finished spun yarn, and 2 is a schematic diagram of spinning wall cloth; The three-dimensional illustration of the second aspect of the spun yarn ^ · The third aspect of the finished spun yarn that is blocked by worsted spinning = the side view of the spun yarn with the yarn end in the tube reserved; Schematic diagram of unwinding yarn head in middle unwinding; 示意图, Schematic diagram of unwinding and applicating yarn head in each package project; Elevation 7: Simplified endurance diagram of the yarn end reserved in the tube during winding project; Figure 8 Figure 9 is a schematic diagram of a winder in a winding project; Fig. 9 is a schematic perspective view of a first embodiment of the yarn clamping device of the present invention; and Fig. 10 is a schematic cross-sectional view taken along line AA of Fig. 9.
