Description
本發明係有關一種具有紗線改變裝置的圓形針織機，尤指一種整合多個紗線改變裝置的圓形針織機。The present invention relates to a circular knitting machine having a yarn changing device, and more particularly to a circular knitting machine incorporating a plurality of yarn changing devices.
為能增加布料編織效果的多樣化，於圓型針織機上搭配紗線改變裝置於編織布料時帶入其他顏色或種類的織線的技術已廣為業界所運用，如美國第US 7,036,343號專利案、第US 7,055,348號專利案、第US 6,655,176號專利案以及第US 5,218,845號專利案等。In order to increase the variety of weaving effects of fabrics, the use of yarn changing devices on circular knitting machines to introduce other colors or types of woven threads into woven fabrics has been widely used in the industry, such as US Pat. No. 7,036,343. , US Pat. No. 7,055,348, US Pat. No. 6,655,176, and US Pat. No. 5,218,845.
以美國第US 5,218,845號專利案為例，其所揭露的紗線改變裝置10，其構造如「圖1-1」至「圖1-4」所示，主要包含有一喂紗板11，一夾切紗板12以及一隔板13。於不喂紗的狀態下，該喂紗板11與該夾切紗板12皆收於該紗線改變裝置10內，該夾切紗板12利用其前端鉤部121將紗線15夾在該夾切紗板12與該隔板13之間；而處於喂紗狀態下，該喂紗板11被驅動向前移動，使其前端111朝外伸出(見「圖1-2」)，並將紗線15向外拉出至喂紗位置，以令織針14得以鉤取進行編織的作業。當該喂紗板11向外移動時，該喂紗板11的尾端112將會碰到夾切紗板12的第一凸點122，用以帶動夾切紗板12朝向喂紗板11同一方向移動，直到喂紗板11移動至外部的喂紗位置時，夾切紗板12前端的鉤部121即釋放紗線15(請參見「圖1-3」)。For example, in the U.S. Patent No. 5,218,845, the yarn changing device 10 is constructed as shown in Figs. 1-1 to 1-4, and mainly includes a yarn feeding plate 11 and a clip. The yarn cutting plate 12 and a partition plate 13. In the state in which the yarn is not fed, the yarn feeding plate 11 and the cutting yarn panel 12 are received in the yarn changing device 10, and the yarn cutting yarn 12 is clamped to the yarn 15 by the front end hook portion 121 thereof. Between the cutting plate 12 and the partition 13; while in the yarn feeding state, the yarn feeding plate 11 is driven to move forward so that the front end 111 projects outward (see "Fig. 1-2"), and The yarn 15 is pulled outward to the yarn feeding position to allow the knitting needle 14 to be hooked for the knitting operation. When the yarn feeding plate 11 is moved outward, the tail end 112 of the yarn feeding plate 11 will hit the first convex point 122 of the clamping yarn plate 12 for driving the clamping yarn cutting plate 12 toward the feeding yarn plate 11 The direction is moved until the yarn feeding plate 11 is moved to the external yarn feeding position, and the hook portion 121 at the front end of the yarn cutting plate 12 releases the yarn 15 (see "Fig. 1-3").
當欲更換其他紗線時，先前伸出至喂紗位置的喂紗板11會被帶回至該紗線改變裝置10內。在喂紗板11收回的過程中，該喂紗板11的鼻部113將會碰到夾切紗板12的第二凸點123，接著連動該夾切紗板12回收移動至紗線改變裝置10內(請參見「圖1-4」)。當完成回收時，該夾切紗板12的鉤部121則利用一剪力切斷紗線15，並再次將該紗線15夾制於該夾切紗板12的鉤部121與該隔板13之間(回到「圖1-1」狀態)。When the other yarns are to be replaced, the yarn feeding plate 11 previously extended to the yarn feeding position is brought back into the yarn changing device 10. During the retraction of the yarn feeding plate 11, the nose portion 113 of the yarn feeding plate 11 will hit the second bump 123 of the clamping yarn panel 12, and then the cutting yarn cutting plate 12 is interlocked and moved to the yarn changing device. Within 10 (see "Figure 1-4"). When the recovery is completed, the hook portion 121 of the clipper yarn panel 12 cuts the yarn 15 by a shearing force, and the yarn 15 is again clamped to the hook portion 121 of the clipping yarn panel 12 and the partition plate. 13 between (return to the "Figure 1-1" state).
前述紗線改變裝置可提供多種不同顏色或種類的紗線，以常見四色紗線改變裝置為例，每一紗線改變裝置包含有四組彼此併排的喂紗板及夾切紗板，以進行四種紗線之間的更換。The yarn changing device can provide a plurality of different colors or kinds of yarns. For example, a common four-color yarn changing device is provided. Each of the yarn changing devices comprises four sets of yarn feeding plates and clipping yarn plates side by side. Replace between the four yarns.
若欲增加更換紗線的數目，亦可於單一紗線改變裝置內增設更多喂紗板與夾切紗板，如具有六組喂紗板與夾切紗板的六色紗線改變裝置。然，可更換的紗線數目愈多，會須要更多的喂紗板與夾切紗板組合，該紗線改變裝置的體積也會越大。如此一來，此一新規格的紗線改變裝置將會減少原本在單一圓形針織機上的配置。若欲維持原本配置的數目而縮小紗線改變裝置的體積，勢必使得其中元件的體積縮小或者厚度變薄，恐導致整體機械強度的可靠性降低。此外，由於喂紗板無論於向外伸出或收回的作動過程中，皆須額外增加一段用來帶動夾切紗板的行程，於單一紗線改變裝置進行越多紗線改變的動作時，將影響編織的速度。If you want to increase the number of yarns to be replaced, you can add more yarn feeding plates and clipping yarn plates in a single yarn changing device, such as a six-color yarn changing device with six sets of yarn feeding plates and clip cutting yarn plates. However, the greater the number of yarns that can be replaced, the more the yarn feeders need to be combined with the jaws, and the larger the volume of the yarn changing device. As a result, this new specification of yarn changing device will reduce the configuration originally on a single circular knitting machine. If the volume of the yarn changing device is to be reduced by maintaining the number of original configurations, it is inevitable that the volume of the components therein is reduced or the thickness is thinned, which may result in a decrease in the reliability of the overall mechanical strength. In addition, since the yarn feeding plate is subjected to an outwardly extending or retracting operation, an additional stroke for driving the cutting yarn plate is required, and when a single yarn changing device performs more yarn changing operations, Will affect the speed of weaving.
為能維持一般紗線改變裝置的設計，並能於該基礎設計下進行更多紗線改變的效果，使圓形針織機進行編織時具有更多的效果變化，習知另一美國專利案，US 7,073,355，揭露一種具有至少一調線附件的針織機(Knitting machine with at least one striping attachment)，主要包含有至少一設有針織工具之托架，一凸輪機構以及一調線裝置。該一凸輪機構具有至少一成圈區段，用於將所選擇之針織工具移入一引紗位置。該調線附件用於將所選擇之紗線喂給至已進入該引紗位置之針織工具。該調線附件具有至少一第一及一第二紗線改變裝置，藉由一嚙合構件將該第一或該第二紗線改變裝置選擇性喂給之紗線，於該成圈區段放入已進入該引紗位置之針織工具。In order to maintain the design of the general yarn changing device and to perform more yarn changing effects under the basic design, the circular knitting machine has more effect changes when weaving, and another US patent case is known. No. 7,073,355 discloses a knitting machine with at least one striping attachment, which mainly comprises at least one bracket provided with a knitting tool, a cam mechanism and a thread adjusting device. The cam mechanism has at least one looping section for moving the selected knitting tool into a yarn take-up position. The thread attachment is used to feed the selected yarn to a knitting tool that has entered the yarn take-up position. The thread attachment has at least one first and a second yarn changing device, and the first or second yarn changing device is selectively fed to the yarn by an engaging member, and is placed in the looping section Enter the knitting tool that has entered the yarn feeding position.
雖然美國第US 7,073,355專利案所揭露的針織機可藉由一嚙合構件，將配置於該第一或第二紗線改變裝置的紗線選擇性帶入成圈區段中。但由於圓型針織機中，變紗改變裝置與織針織間的空間狹小，該嚙合構件需要活動設置於其中，因此在裝設上相當不便，且於不帶入紗線的狀態下，該嚙合構件可能造成編織上的空間障礙。另外，該嚙合構件利用一夾住機構來夾制紗線，因此，該夾住機構相對於紗線的鬆緊將影響紗線是否能帶入成圈區段，並為針織工具所編織。若紗線因夾制力太大無法順利脫離嚙合構件，或因夾制力不足而提早脫離嚙合構件，都將造成紗線改變無法順利進行，而影響編織物的品質。The knitting machine disclosed in U.S. Patent No. 7,073,355, the entire disclosure of which is incorporated herein by reference in its entirety in its entire entire entire entire entire entire entire entire extent However, since the space between the yarn changing device and the woven knitting machine is narrow in the circular knitting machine, the engaging member needs to be movably disposed therein, so that it is rather inconvenient to install, and the meshing is performed without the yarn being introduced. The components may cause space obstacles in the weaving. In addition, the engaging member clamps the yarn by a gripping mechanism, so that the tension of the gripping mechanism relative to the yarn will affect whether the yarn can be carried into the looped section and woven by the knitting tool. If the yarn is too large to be able to smoothly disengage from the engaging member due to the clamping force, or the early disengagement of the engaging member due to insufficient clamping force, the yarn change will not proceed smoothly, and the quality of the knitted fabric will be affected.
本發明之主要目的為於圓型針織機編織的過程中，得以擴充紗線顏色或種類改變的數量，並且避免在增加紗線改變的同時影響編織品質。為達上述目的，本發明提供一種整合多紗線改變裝置的圓形針織機，包括有一第一、第二變紗裝置，一驅動凸輪組，以及至少一具有複數織針的針筒座。該第一變紗裝置以及該第二變紗裝置分別具有至少一第一喂紗機構以及至少一第二喂紗機構，該第一喂紗機構以及該第二喂紗機構分別經過一第一喂紗行程以及一第二喂紗行程向外移動至一喂紗位置以提供紗線。該驅動凸輪組包含有分別推動該第一、第二喂紗機構進行該第一、第二喂紗行程的第一驅動軌道及第二驅動軌道，該第二驅動軌道中更具有一驅動延遲區段使該第二喂紗機構進行該第二喂紗行程與該第一喂紗機構進行該第一喂紗行程之間產生一喂紗時差。該針筒座內至少相對於該第一、第二喂紗機構的喂紗位置之間的織針導引移動至一鉤紗位置藉由該第一、第二喂紗機構的喂紗時差分別鉤取來自該第一、第二喂紗機構於喂紗位置所提供的紗線。The main object of the present invention is to expand the number of yarn color or type changes during the knitting of the circular knitting machine, and to avoid affecting the knitting quality while increasing the yarn change. To achieve the above object, the present invention provides a circular knitting machine incorporating a multi-yarn changing device comprising a first and second yarn changing device, a driving cam set, and at least one pin holder having a plurality of knitting needles. The first yarn-changing device and the second yarn-changing device respectively have at least one first yarn feeding mechanism and at least one second yarn feeding mechanism, and the first yarn feeding mechanism and the second yarn feeding mechanism respectively pass a first feeding mechanism The yarn stroke and a second yarn feed stroke are moved outward to a yarn feeding position to provide the yarn. The driving cam group includes a first driving track and a second driving track for respectively pushing the first and second yarn feeding mechanisms to perform the first and second yarn feeding strokes, and the second driving track further has a driving delay zone The segment causes the second yarn feeding mechanism to perform a second yarn feeding stroke and the first yarn feeding mechanism to generate a yarn feeding time difference between the first yarn feeding stroke. At least the yarn guides between the yarn feeding positions of the first and second yarn feeding mechanisms are moved to a hook yarn position by the first and second yarn feeding mechanisms. The yarns supplied from the first and second yarn feeding mechanisms at the yarn feeding position are hooked.

The invention does not need to add other members between the yarn changing device and the knitting needle, so that no space obstacle in the yarn feeding process is generated. On the other hand, the present invention still directly supplies the yarn to the knitting needle by the yarn feeding mechanism of the yarn converting device, thereby preventing the yarn from being loosened or being unable to be hooked by the knitting needle due to the pulling of other members.

The second yarn feeding plate 32 has a head end 321 and a tail end 322. The tail end 322 protrudes from a second outwardly extending bump 323 and a second returning bump 324. The second outwardly extending projection 323 of the second yarn feeding plate 32 is urged to drive the second yarn feeding plate 32 to perform a second yarn feeding stroke, and the head end 321 is moved to the outside of the second yarn converting device 30. To the yarn feeding position, the yarn 52 passing through the yarn end 325 of the head end 321 is taken out. The second clipper plate 33 is interlocked with the second yarn feeder 32. The second yarn feeding mechanism 31 further has a second plate lever 34 including a returning convex portion 341 and a selection convex portion 342. When the homing convex portion 341 is pressed by force, the second plate lever 34 is in an activated position; at this time, the second outwardly extending projection 323 of the second yarn feeding plate 32 is exposed to the second variable yarn Outside of device 30. If the selection protrusion 342 is pressed by force, the second plate lever 34 is in a locked position; at this time, the second outward protrusion 323 of the second yarn feeding plate 32 is returned to the second yarn changing device 30.

The homing cam 44 is disposed at a position corresponding to the homing convex portions 241, 341 of the first and second plate levers 24, 34. When the homing cam 44 travels to the first and second yarn changing devices 20, 30, a pressure is applied to all of the homing protrusions 241, 341 on the first and second plate levers 24, 34. The first and second plate levers 24, 34 are both in the activated state. The selector 45 includes a plurality of strikers 451 selectively protruding from the surface of the selector 45, and correspondingly triggering the selected protrusions 242, 342 of the first and second plate levers 24, 34, When the force is pressed, the convex portions 242, 342 are selected to drive the first and second plate rods 24, 34 in the locked position.

當該第一變紗裝置20與該第二變紗裝置30經過該歸位凸輪44與該選擇器45的驅動後，剩餘具有仍處於啟動位置第一、第二板機桿24、34的第一、第二喂紗機構21、31，其該第一、第二去程凸塊223、323顯露凸出於該第二變紗裝置30外側得以受到後續第一、第二去程凸輪41、42的推動。如『圖6-1』所示，該驅動凸輪組40的第一去程凸輪41與第二去程凸輪42皆未觸碰到該第一、第二喂紗機構21、31的第一、第二去程凸塊223、323。該第一、第二喂紗機構21、31的第一、第二喂紗板22、32皆收於該第一、第二變紗裝置20、30內並未進行作動，如『圖7-1』所示。當該驅動凸輪組40逐漸接近該第一、第二喂紗機構21、31。首先，該第一變紗裝置20內的第一喂紗機構21會與該第二去程凸輪42的引導區段421接觸，如『圖6-2』所示。該第一喂紗板22尾端222進入該第一驅動軌道時，該第一去程凸塊223受到該引導區段421的推壓，而使得該第一喂紗板22與該第一夾切紗板23進行該第一喂紗行程。隨著該第一、第二去程凸輪41、42繼續朝向該第二變紗裝置30移動，該第二喂紗板32尾端322的第二去程凸塊323亦受到該引導區段421的推壓，而使得該第二喂紗板32與該第二夾切紗板33進行該第二喂紗行程。此時，該第一喂紗機構21與第二喂紗機構31皆未達到喂紗位置，無法提供紗線51、52至織針70，如『圖7-2』所示。After the first yarn-changing device 20 and the second yarn-changing device 30 are driven by the homing cam 44 and the selector 45, the remaining first and second plate levers 24, 34 are still in the activated position. a second yarn feeding mechanism 21, 31, wherein the first and second outwardly extending projections 223, 323 are exposed to the outside of the second yarn-changing device 30 to be subjected to the subsequent first and second outward-going cams 41, The promotion of 42. As shown in FIG. 6-1, the first outward cam 41 and the second outward cam 42 of the driving cam group 40 do not touch the first of the first and second yarn feeding mechanisms 21, 31, The second outward going bumps 223, 323. The first and second yarn feeding plates 22, 32 of the first and second yarn feeding mechanisms 21, 31 are all received in the first and second yarn converting devices 20, 30, such as "Figure 7- 1" is shown. When the driving cam group 40 gradually approaches the first and second yarn feeding mechanisms 21, 31. First, the first yarn feeding mechanism 21 in the first yarn-changing device 20 is in contact with the guiding portion 421 of the second outward-going cam 42, as shown in Fig. 6-2. When the tail end 222 of the first yarn feeding plate 22 enters the first driving track, the first outwardly extending protrusion 223 is pressed by the guiding portion 421, so that the first feeding plate 22 and the first clamping plate 22 The cutting plate 23 performs the first yarn feeding stroke. As the first and second outward-going cams 41, 42 continue to move toward the second yarn-changing device 30, the second outward-gearing projection 323 of the trailing end 322 of the second yarn-feeding plate 32 is also subjected to the guiding section 421. The pressing of the second yarn feeding plate 32 and the second cutting yarn plate 33 is performed for the second yarn feeding stroke. At this time, neither the first yarn feeding mechanism 21 nor the second yarn feeding mechanism 31 reaches the yarn feeding position, and the yarns 51 and 52 cannot be supplied to the knitting needle 70, as shown in Fig. 7-2.
由於該第一喂紗板22的第一去程凸塊223具有較低之下緣，當該第一喂紗機構21之第一喂紗板22尾端222沿著該第一驅動軌道完成該引導區段421的移動，將進入直接受到亦屬於較低位置的第一釋紗區段411的驅動，如『圖6-3』所示。如此，當該第一喂紗機構21完成第一喂紗行程，該第一喂紗板22的頭端221可跨過該給紗器80的給紗部82到達喂紗位置且該第一夾切紗板23釋放紗線51，使該紗線51可以為處於鉤紗位置的織針70所鉤取，如『圖7-3』所示。另一方面，具有較高下緣的第二喂紗板32的第二去程凸塊323無法碰觸到較低的第一釋紗區段411，轉而進入該第二去程凸輪42的驅動延遲區段422。此時，該第二喂紗板32仍未完成第一喂紗行程，無法將紗線52提供至處於鉤紗位置的織針70。Since the first outwardly extending protrusion 223 of the first yarn feeding plate 22 has a lower lower edge, when the trailing end 222 of the first yarn feeding plate 22 of the first yarn feeding mechanism 21 is completed along the first driving track The movement of the guiding section 421 will enter the driving directly to the first yarn releasing section 411 which also belongs to the lower position, as shown in Fig. 6-3. Thus, when the first yarn feeding mechanism 21 completes the first yarn feeding stroke, the head end 221 of the first yarn feeding plate 22 can reach the yarn feeding position and the first folder across the yarn feeding portion 82 of the yarn feeder 80. The yarn cutting plate 23 releases the yarn 51 so that the yarn 51 can be hooked by the knitting needle 70 at the hooking position, as shown in Fig. 7-3. On the other hand, the second outwardly extending projection 323 of the second yarn feeding plate 32 having the higher lower edge cannot touch the lower first yarn releasing section 411 and enters the second outward traveling cam 42 instead. Drive delay section 422. At this time, the second yarn supplying plate 32 has not completed the first yarn feeding stroke, and the yarn 52 cannot be supplied to the knitting needle 70 at the hooking position.
當該第二喂紗板32的第二去程凸塊323完成該驅動延遲區段422後，則被該第二釋紗區段423所推動，如『圖6-4』所示。受到該第二釋紗區段423所驅動的第二喂紗機構31，完成該第二喂紗行程，該第二喂紗板32的頭端321亦可跨過給紗器80的給紗部82到達喂紗位置，且該第二夾切紗板33釋放紗線52，使紗線52為處於鉤紗位置的織針70所鉤取，如『圖7-4』所示。此時，該第一、第二喂紗機構21、31皆可提供紗線51、52給織針70。如此一來，即可於單一編織過程中，增加喂給編織物其他顏色或種類紗線的數量。When the second out-going bump 323 of the second yarn feeding plate 32 completes the driving delay section 422, it is pushed by the second yarn releasing section 423, as shown in FIG. 6-4. The second yarn feeding mechanism 31 driven by the second yarn releasing section 423 completes the second yarn feeding stroke, and the head end 321 of the second yarn feeding plate 32 can also pass over the yarn feeding portion of the yarn feeder 80. 82 reaches the yarn feeding position, and the second jaw cutting plate 33 releases the yarn 52, so that the yarn 52 is hooked by the knitting needle 70 at the hooking position, as shown in Fig. 7-4. At this time, the first and second yarn feeding mechanisms 21, 31 can supply the yarns 51, 52 to the knitting needles 70. In this way, the number of other colors or types of yarns fed to the braid can be increased during a single weaving process.
最後，若欲停止紗線51、52的供應，處於啟動位置的第一、第二板機桿24、34經過該歸位凸輪44與該選擇器45的再次驅動，而轉變成處於閉鎖位置。因此，該第一、第二喂紗板22、32的第一、第二去程凸塊223、323回收於該第一、第二變紗裝置20、30內，而該第一、第二回程凸塊224、324則凸出於該第一、第二變紗裝置20、30外側，如『圖8-1』所示。露出的該第一回程凸塊224與該第二回程凸塊324，可受到該回程凸輪43的帶動，而向後位移，請參閱『圖8-2』至『圖8-4』所示，使該第一喂紗機構21與該第二喂紗機構31由原本供應紗線51、52的喂紗位置退入該第一、第二變紗裝置20、30內，該第一、第二夾切紗板23、33受到該第一、第二喂紗板22、32的連動更進一步切斷並夾制該紗線51、52。Finally, if the supply of the yarns 51, 52 is to be stopped, the first and second trigger levers 24, 34 in the activated position are again driven by the homing cam 44 and the selector 45 to be in the latched position. Therefore, the first and second outwardly extending projections 223, 323 of the first and second yarn feeding plates 22, 32 are recovered in the first and second yarn-changing devices 20, 30, and the first and second The return bumps 224, 324 protrude from the outside of the first and second yarn changing devices 20, 30, as shown in Fig. 8-1. The exposed first returning lug 224 and the second returning lug 324 can be driven by the returning cam 43 and displaced backwards, as shown in FIG. 8-2 to FIG. 8-4, so that The first yarn feeding mechanism 21 and the second yarn feeding mechanism 31 are retracted into the first and second yarn converting devices 20, 30 from the yarn feeding positions of the original yarns 51, 52, the first and second clips. The yarn cutting plates 23, 33 are further cut by the interlocking of the first and second yarn feeding plates 22, 32 and the yarns 51, 52 are sandwiched.
於本發明中，該第一喂紗機構21與該第二喂紗機構31的第一、第二去程凸塊223、323分別沿著該第一驅動軌道以及該第二驅動軌道被推動，相較於該第一驅動軌道，該第二驅動軌道更多了該驅動延遲區段422，如此使該第一、第二喂紗機構21、31到達喂紗位置的時間點不一樣，也就是說該第二喂紗機構31進行該第二喂紗行程與該第一喂紗機構21進行該第一喂紗行程之間產生一喂紗時差。In the present invention, the first and second outwardly extending projections 223 and 323 of the first yarn feeding mechanism 21 and the second yarn feeding mechanism 31 are respectively pushed along the first driving rail and the second driving rail. Compared with the first driving track, the second driving track has more of the driving delay section 422, so that the time when the first and second yarn feeding mechanisms 21, 31 reach the feeding position is different, that is, It is said that the second yarn feeding mechanism 31 performs a yarn feeding time difference between the second yarn feeding stroke and the first yarn feeding mechanism 21 to perform the first yarn feeding stroke.
綜上所述，本發明整合多紗線改變裝置的圓形針織機，其第一變紗裝置與該第二變紗裝置中的第一喂紗機構與第二喂紗機構不同時移動至喂紗位置，並產生一喂紗時差。藉由此喂紗時差，該第一喂紗機構以及該第二喂紗機構的紗線可分別為位於鉤紗位置的織針鉤取，以達到於單一編織過程中納入多樣紗線的目的。因此本發明極具進步性及符合申請發明專利之要件，爰依法提出申請，祈 鈞局早日賜准專利，實感德便。In summary, the circular knitting machine incorporating the multi-yarn changing device of the present invention has the first yarn-changing device and the first yarn-feeding mechanism and the second yarn-feeding mechanism in the second yarn-changing device not moving to the same. The yarn position and produces a yarn feed time difference. By means of the yarn feeding time difference, the yarns of the first yarn feeding mechanism and the second yarn feeding mechanism can respectively be hooked at the hook yarn position to achieve the purpose of incorporating a plurality of yarns in a single knitting process. Therefore, the present invention is highly progressive and conforms to the requirements of the invention patent application, and the application is filed according to law, and the praying office grants the patent as soon as possible.
