Description
本發明關於一種對被製造成筒狀或管狀的織物(例如襪子)的開口邊緣進行縫合的方法與機器,特別是使用一對織針的縫紉機與編織方法。The present invention relates to a method and a machine for stitching the opening edge of a fabric (such as a socks) manufactured into a tube or tube, especially a sewing machine and a knitting method using a pair of knitting needles.
管狀針織品(例如襪子)是使用圓編針織機(cylindrical knitting machines)生產的。生產時,管狀針織品的兩端具有開口,其中一端(腳趾套)會從針織機的織針移動至進行編織縫合另一工作站(station)。將管狀針織品移動至腳趾袋縫合工作站的作業可以採取手動操作,或者為專利EP2377979所描述的自動化方式進行。Tubular knitwear (such as socks) is produced using circular knitting machines (cylindrical knitting machines). During production, both ends of the tubular knitwear have openings, and one end (toe cover) is moved from the knitting needle of the knitting machine to another station for knitting and sewing. The operation of moving the tubular knitwear to the toe bag stitching station can be performed manually or in an automated manner described in patent EP2377979.
如EP2377979所述,當針織機上所進行的襪子編織循環完成,在最後編織排(last-to-knit rank)的線圈會分別從織針上進行接收,將最後編織排的多數線圈區分為2個半數編織排(semi-rank),並移動其中一半數編織排與另一半數編織排相互對應疊合。此疊合作業是利用圓周機構執行,該圓周機構包含能180度旋轉的一對半圓元件,其中一半圓元件能夠在另一半圓元件上擺動,同時讓所有線圈沿著一個半圓周排列且對應形成多數個兩兩一組的線圈組(pair of stitches)。隨著圓周機構的作動,成對的線圈組被移動至預備進行縫合的位置,以縫合管狀織物的一端開口(腳趾套)。As described in EP2377979, when the sock knitting cycle performed on the knitting machine is completed, the stitches in the last-to-knit rank will be received from the knitting needles, and the majority of the stitches in the last knit rank are divided into 2 Half of the braided rows (semi-rank), and move half of the braided rows and the other half of the braided rows to overlap each other correspondingly. This stacking operation is performed by a circular mechanism, which includes a pair of semicircular elements that can rotate 180 degrees, of which the semicircular element can swing on the other semicircular element, and at the same time all the coils are arranged along a semicircle and formed correspondingly Most pairs of stitches (pair of stitches). With the action of the circular mechanism, the pair of stitches are moved to the position where they are ready to be sewn, so as to sew one end of the tubular fabric (toe cover).
被設計用於縫合腳趾套的編織機構可能需要一個或二個織針,具有單一織針的針織機用於將一條織線形成線圈,而具有二織針的針織機用於將二條織線形成編織環(knitting loop)。A knitting mechanism designed to sew toe covers may require one or two knitting needles. A knitting machine with a single needle is used to form one thread into a loop, and a knitting machine with two needles is used to form two threads. Knitting loop.
在習用的技術上,已知使用具有一織針的機器縫合襪子腳趾套時仍存在缺陷,例如織線散開的風險。In the conventional technology, it is known that there are still defects when sewing the toe cover of the sock with a machine with a knitting needle, such as the risk of the knitting thread falling apart.
具有二織針的針織機基本上包括一織針(needle),一個針形鉤針(needle-shaped hook)和一個用於打結的釘(peg)。A knitting machine with two knitting needles basically includes a needle, a needle-shaped hook and a peg for knotting.
針織機的織針及鉤針在接近尖端邊緣的位置均穿設有孔洞可分別供一織線穿過。當織針穿入線圈組,移動進入線圈組一側並於另一側穿出,將同時拉起織線穿過線圈組。當織針連帶織線穿過線圈組之後,織針的織線將被鉤針保留。織針從已穿入的最後線圈撤回,同時,保留在鉤針的織線遺留位於線圈組內。藉此,線圈組以雙結打結。The knitting needles and crochet needles of the knitting machine are provided with holes at positions close to the edge of the tip for a knitting thread to pass through. When the knitting needle penetrates into the loop group, it moves into one side of the loop group and passes out on the other side, simultaneously pulling the knitting thread through the loop group. When the knitting needle and the knitting thread pass through the loop group, the knitting thread of the knitting needle will be retained by the crochet needle. The knitting needle is withdrawn from the last stitch that has been penetrated, and at the same time, the knitting thread remaining in the crochet needle is located in the stitch group. In this way, the coil assembly is knotted with a double knot.
上述作業會逐一於每一個成對的線圈組重複進行,直到完成腳趾套縫合步驟。當腳趾套縫合完成,織針上沒有遺留可編織的成對的線圈組。因此,針織縫線(thread knots)會放置於縫線形成柄(knot making peg)。縫線形成柄的尖端向外移動,並具有供針織縫線放置的錐狀部分(conical shape)。藉此,形成一個額外的針織縫線(extra thread knot)。在此位置,額外針織縫線的一端保留在管狀針織品(襪子),而另一端位於縫線形成柄,因此需要被剪裁釋放。當額外針織縫線被剪裁釋放,部分的額外針織縫線遺留在襪子,而額外針織縫線另一部分保留在縫線形成柄。額外針織縫線保留在縫線形成柄的部分,被定位成下一個鄰近延續襪子的腳趾套的編織起始端。因此,預定長度的針織縫線能夠藉由此方法保留在製造襪子的腳趾套編織過程的起始端以及結束端。The above operations will be repeated for each pair of stitches one by one until the toe cuff stitching step is completed. When the toe cover is stitched, there is no pair of stitches left on the knitting needles that can be knitted. Therefore, thread knots are placed on the knot making peg. The tip of the suture forming handle moves outwards, and has a conical shape where the knitting suture is placed. In this way, an extra thread knot is formed. In this position, one end of the extra knitting suture remains in the tubular knitwear (sock), while the other end is located at the suture forming handle, so it needs to be cut and released. When the extra knitting stitches are cut and released, part of the extra knitting stitches is left in the sock, and another part of the extra knitting stitches remains in the stitch forming handle. The additional knitting stitches remain in the part where the stitches form the handle, and are positioned next to the knitting start end of the toe cover of the continuation sock. Therefore, a predetermined length of knitting suture can be retained at the beginning and end of the knitting process of the toe cover of the sock by this method.
理想的情況下,保留於襪子腳趾套起始端及結束端的針織縫線應具有近似長度,一般來說,介於8至10 毫米(mm)。另一方面,除了保留在製造襪子的腳趾套編織過程的起始端以及結束端的針織縫線,在襪子最後編織排編織後,多種長度的織線片段也會被遺留在襪子。Ideally, the knitting stitches retained at the start and end of the toe cover of the sock should have an approximate length, generally between 8 and 10 millimeters (mm). On the other hand, in addition to the knitting stitches remaining at the beginning and end of the knitting process of the toe cover of the socks, after the knitting of the last knitting row of the socks, the knitting thread fragments of various lengths will also be left in the socks.
習用技術已有許多用於裁切外部針織縫線的機器以及用於該機器的方法,如專利EP 2300653所描述,裁刀設置於縫紉機頭以裁切在預定距離的針織縫線,如同裁刀與縫線形成柄之間的距離。然而,專利EP 2300653所述之機器無法裁切在編織後(幾乎是標準長度)形成於襪子的兩端的針織縫線,並且在襪子的最後編織排編織後,也無法裁切遺留在襪子的織線片段(即屬於襪子的織線片段)。因此,襪子的最後編織排編織後,遺留在襪子的織線片段很可能具有在各個方向任意懸掛的鬆散末端。The conventional technology has many machines for cutting external knitting sutures and methods for such machines. As described in patent EP 2300653, the cutting knife is set on the sewing machine head to cut the knitting sutures at a predetermined distance, like a cutting knife. Form the distance between the shank and the suture. However, the machine described in patent EP 2300653 cannot cut the knitting stitches formed at both ends of the socks after knitting (almost standard length), and after knitting the last knitting row of the socks, it cannot cut the knitting left in the socks. Thread fragments (that is, woven thread fragments belonging to socks). Therefore, after the last knitting row of the sock is knitted, the strands of the knitting thread left in the sock are likely to have loose ends hanging arbitrarily in all directions.

The suction pipe (33) is arranged on the upper part of the cutting tool arm (30). The suction pipe (33) extends to the rear of the movable knife (32). When the movable cutter (32) is in the lower position
當編織作業推進至縫合管狀針織物開口的階段,如圖3所示,成對的線圈組(42)沿著如專利EP 2377979所述之半圓周排列而被縫合。同時,用於編織作業的織針(1)及鉤針(2)被定位而垂直於成對的線圈組(42)的水平織軸(41),如圖3所示。同時切割工具臂(30)被定位而鄰近於被縫合之線圈組(42)的軌跡。在此位置時,形成針織縫線的工作站與針織縫線將被線切割裝置裁切的位置之間距離約30毫米(mm)。 When the knitting operation progresses to the stage of sewing the opening of the tubular knitted fabric, as shown in Fig. 3, the paired loop sets (42) are arranged along the semicircle as described in the patent EP 2377979 and are stitched. At the same time, the knitting needles (1) and the crochet needles (2) used for knitting operations are positioned perpendicular to the horizontal knitting axis (41) of the paired stitch group (42), as shown in FIG. 3. At the same time, the cutting tool arm (30) is positioned adjacent to the track of the stitched coil group (42). In this position, the distance between the workstation where the knitting suture is formed and the position where the knitting suture will be cut by the thread cutting device is about 30 millimeters (mm).
如圖4所示,當織針(1)設置於縫紉機頭(20),且欲編織的第一個成對的線圈組(42)彼此排列對齊,織針(1)的尖端與穿設於鄰近尖端的洞(1a)的織線穿過成對的線圈組(42)。在織針(1)穿出之第一組線圈組(42)之前,鉤針(2)抓住穿設於織針(1)的織線,織線先從鉤針(2)尖端的洞(2a)被拉出,織針(1)穿出成對的線圈組(42)並留下織線位於成對的線圈組(42)中。因此,第一組成對的線圈組(42)被編織縫合在一起。當縫合第一個成對的線圈組(42)時,已保留在縫線形成柄(3)的針織縫線(44b)也位於第一組成對的線圈組(42)上。 As shown in Figure 4, when the knitting needle (1) is set on the sewing machine head (20), and the first pair of stitches (42) to be knitted are aligned with each other, the tip of the knitting needle (1) is aligned with each other. The knitting thread of the hole (1a) adjacent to the tip is passed through the paired loop group (42). Before the knitting needle (1) passes through the first set of stitches (42), the crochet needle (2) grabs the knitting thread passing through the knitting needle (1), and the knitting thread first passes through the hole (2a) at the tip of the crochet needle (2) ) Is pulled out, and the knitting needle (1) passes through the paired stitch group (42) and leaves the knitting thread in the paired stitch group (42). Therefore, the coil group (42) of the first pair is knitted and stitched together. When sewing the first paired stitch group (42), the knitting stitches (44b) that have been retained on the stitch forming handle (3) are also located on the first paired stitch group (42).
當第一組成對的線圈組(42)完成編織,半圓元件所攜帶的成對的線圈組(42)用已知的方式以方向43繞織軸(41)旋轉。藉此,第二組成對的線圈組(42)會對齊織針(1)。編織作業會以編織方向(5)(如圖12所示)重複至所有成對的線圈,形成針織縫線(42a)至線圈組(42)。接著,針織縫線(44b)固定於第一組成對的線圈組(42)推進朝向線切割裝置的刀具。
When the first pair of stitches (42) is knitted, the pair of stitches (42) carried by the semicircular element is rotated in a
如圖5所示,活動刀具(32)部分地向上移動(32a)遠離固定刀具(31),並因此開啟吸氣管(33)的進氣孔(33a)。設置在第一組線圈組(42)的針織縫線(44b)被吸入吸氣管(33)的進氣孔(33a)。接著,固定在第一組線圈組的針織縫線(44b)被定位在固定刀具(31)與活動刀具(32)之間。 As shown in Fig. 5, the movable cutter (32) partially moves upward (32a) away from the fixed cutter (31), and therefore opens the air inlet (33a) of the suction pipe (33). The knitting stitches (44b) provided in the first stitch group (42) are drawn into the air inlet (33a) of the suction pipe (33). Next, the knitting suture (44b) fixed in the first stitch group is positioned between the fixed knife (31) and the movable knife (32).
如圖6所示,當活動刀具(32)向下移動(32a),針織縫線(44b)被剪裁,並在保留約8至10毫米(mm)長度的片段在襪子上。針織縫線(44b)的另一片段被吸氣管(33)吸入處理。 As shown in Fig. 6, when the movable knife (32) moves downward (32a), the knitting suture (44b) is cut, and a segment with a length of about 8 to 10 millimeters (mm) is retained on the sock. Another segment of the knitted suture (44b) is sucked and processed by the suction pipe (33).
當所有成對的線圈組(42)的編織作業完成時,必須形成額外針織縫線(44)。額外針織縫線(44)於縫線形成柄(3)產生,縫線形成柄(3)的錐狀尖端(3a)可向外移動,並且縫線形成柄(3)具有錐狀部位可供針織縫線(4)放置。藉此,當30至40毫米(mm)長度的額外針織縫線(44)形成,縫紉機頭(20)以軸(29)為軸心而沿著方向(29a)部分轉動,進而遠離從線圈組(42)。在此作動下,最後形成的針織縫線(44)被定位在固定刀具(31)與活動刀具(32)之間,而刀具因活動刀具(32)向上運動而打開。在此位置時,設置於縫紉機頭(20)的縫線形成柄(3)的尖端(3a)與線切割裝置之刀具之間間隔約20至30毫米(mm)的距離。 When the knitting operation of all the paired loop sets (42) is completed, additional knitting stitches (44) must be formed. Additional knitting stitches (44) are produced on the stitch forming handle (3), the tapered tip (3a) of the stitch forming handle (3) can move outward, and the stitch forming handle (3) has a tapered part for Place the knitted suture (4). Thereby, when an additional knitting stitch (44) with a length of 30 to 40 millimeters (mm) is formed, the sewing machine head (20) rotates partly along the direction (29a) with the shaft (29) as the axis, and then moves away from the stitch group (42). Under this action, the finally formed knitting suture (44) is positioned between the fixed knife (31) and the movable knife (32), and the knife is opened due to the upward movement of the movable knife (32). When in this position, the distance between the tip (3a) of the thread forming handle (3) and the cutter of the thread cutting device arranged on the sewing machine head (20) is about 20-30 millimeters (mm).
如圖9所示,活動刀具(32)向下移動時,針織縫線被裁切成二段,其中一段約8至10毫米(mm)的片段遺留在襪子,長度約20至30毫米(mm)的另一片段保留在縫線形成柄(3)。 As shown in Figure 9, when the movable knife (32) moves down, the knitting suture is cut into two sections, one of which is about 8 to 10 millimeters (mm) left in the sock, and the length is about 20 to 30 millimeters (mm). The other segment of) remains in the suture forming handle (3).
如圖10所示,當腳趾袋被縫合且針織縫線(44a,44b)被剪裁,縫紉機頭(20)沿著其軸(29)為軸心而沿著方向(29aa)完全轉動約90度。同時,切割工具臂(30)會以臂軸(39)為軸心而沿著方向(39a)轉動,並因第二檔件(14)的設置而僅部分旋轉,因此從設置線圈組的半圓元件移開。 As shown in Figure 10, when the toe bag is sewn and the knitting sutures (44a, 44b) are cut, the sewing machine head (20) rotates about 90 degrees along the direction (29aa) along its axis (29) as its axis. . At the same time, the cutting tool arm (30) will rotate along the direction (39a) with the arm shaft (39) as the axis, and will only partly rotate due to the setting of the second gear (14). The component is moved away.
前述實施例所提供縫紉機能夠用於縫合管狀針織物開口,所使用編織方法如後。首先,縫紉機頭(20)位於編織位置,管狀針織物的開口形成沿著半圓周排列的線圈組(42),縫紉機頭(20)導入織線(4)接續原有的針織縫線(44b)開始編織形成針織縫線(42a)。接著,開啟吸氣管(33)的進氣孔(33a)吸附需要被剪 裁的針織縫線(44b),利用刀具剪裁針織縫線(44b),並持續編織形成針織縫線(42a)以縫合連接線圈組(42)直到所有線圈組(42)的編織作業完成。隨後再利用縫紉機頭(20)形成額外的針織縫線(44),驅轉縫紉機頭(20)部分轉動而偏離編織位置並靠近切割工具臂(30),使額外的針織縫線(44)被定位於固定刀具(31)與活動刀具(32)之間,如圖8與圖11B所示,並利用刀具裁切額外的針織縫線(44)使分割為二針織縫線(44a,44b)。最後,驅轉縫紉機頭(20)完全轉動並使切割工具臂(30)部分轉動,讓切割工具臂(30)遠離。 The sewing machine provided in the foregoing embodiment can be used to sew the openings of the tubular knitted fabric, and the knitting method used is as follows. First, the sewing machine head (20) is located at the knitting position, the openings of the tubular knitted fabric form a loop group (42) arranged along a half circle, and the sewing machine head (20) introduces the knitting thread (4) to continue the original knitting suture (44b) Start weaving to form knitted stitches (42a). Next, open the air inlet (33a) of the suction pipe (33) to absorb the need to be cut The cut knitting suture (44b) is cut with a knife to cut the knitting suture (44b), and continue to knit to form a knitting suture (42a) to sew the connecting stitch group (42) until the knitting operation of all the stitch groups (42) is completed. Then the sewing machine head (20) is used to form additional knitting stitches (44), and the sewing machine head (20) is driven to partly rotate to deviate from the knitting position and approach the cutting tool arm (30), so that the extra knitting stitches (44) are Positioned between the fixed knife (31) and the movable knife (32), as shown in Figure 8 and Figure 11B, and use the knife to cut the extra knitting stitches (44) to divide into two knitting stitches (44a, 44b) . Finally, the sewing machine head (20) is driven to rotate completely and the cutting tool arm (30) is partially rotated to keep the cutting tool arm (30) away.
當要對另一管狀針織物的開口進行縫合時,在重複前段的步驟即可。因此,本發明藉由獨立於縫紉機頭設置的線切割裝置。可以對形成於管狀針織物兩端的針織縫線進行裁切,並可調整所裁切針織縫線的長度(即線切割裝置與縫線形成柄之間的距離)。 When sewing the opening of another tubular knitted fabric, repeat the steps in the previous section. Therefore, the present invention uses a wire cutting device that is independent of the sewing machine head. The knitting stitches formed at both ends of the tubular knitted fabric can be cut, and the length of the cut knitting stitches (that is, the distance between the thread cutting device and the stitch forming handle) can be adjusted.
