較佳實施例之詳細說明Detailed description of the preferred embodiment

縫紉機1具有基板2，其具有從其向上延伸的機座3和彎成角度的臂4。該臂以機頭5為端部。基板2、機座3，臂4和機頭5被縫紉機1的殼體6包圍。在該臂4中可旋轉地安裝有臂軸(在圖中未示出)。該臂軸在機頭5中經由曲柄連桿機構驅動在機頭5中軸向可移動安裝的針桿7。針桿7在其下端具有機針8。機針通過曲柄連桿機構在豎直軸上可上下運動。機針8在針眼中引導從線圈(未示出)輸送的針線(也未示出)。The sewing machine 1 has a base plate 2 having a base 3 extending upwardly therefrom and an angled arm 4. The arm has the head 5 as its end. The base plate 2, the machine base 3, the arm 4 and the machine head 5 are surrounded by the housing 6 of the sewing machine 1. An arm shaft (not shown in the figure) is rotatably installed in the arm 4. The arm shaft in the handpiece 5 drives the needle bar 7 which is movably installed in the axial direction in the handpiece 5 via a crank linkage mechanism. The needle bar 7 has a needle 8 at its lower end. The needle can move up and down on a vertical shaft through a crank connecting rod mechanism. The needle 8 guides the needle thread (also not shown) fed from the loop (not shown) in the eye of the needle.

基板2支撐底板9，借助縫紉機1進行縫製的縫紉材料可以放置在底板9上。底板9分為幾個部分。底板9的一部分是針板10(例如參見圖2)，該針板擰緊在基板2上。對於非針送布縫紉機1而言，針板具有供機針8穿過的針孔11。此外，針板10具有矩形的穿通孔12，下方滑塊13的上回行段穿過該穿通孔。下方滑塊13以公知的方式與驅動軸驅動連接，該驅動軸設置在基板2下面。對於針送布縫紉機1而言，針孔11可以設計在下方滑塊13中。The base plate 2 supports the base plate 9, and the sewing material sewn by the sewing machine 1 can be placed on the base plate 9. The bottom plate 9 is divided into several parts. A part of the bottom plate 9 is a needle plate 10 (see FIG. 2 for example), which is screwed on the base plate 2. For the non-needle-feed sewing machine 1, the needle plate has a needle hole 11 through which the needle 8 passes. In addition, the needle plate 10 has a rectangular through hole 12 through which the upper loop section of the lower slider 13 passes. The lower slider 13 is drivingly connected with a drive shaft in a known manner, and the drive shaft is arranged under the base plate 2. For the needle-fed sewing machine 1, the needle hole 11 can be designed in the lower slider 13.

縫紉機1進行縫製時，夾緊器14以公知的方式與機針8配合，該夾緊器可以圍繞垂直的夾緊軸旋轉。在夾緊器14的夾緊主體15中，安裝有用於容納剩餘夾緊線或底線的鍋狀梭殼。When the sewing machine 1 is sewing, the clamp 14 is engaged with the needle 8 in a known manner, and the clamp can rotate around a vertical clamping axis. In the clamping body 15 of the clamp 14, a pot-shaped bobbin case for accommodating the remaining clamping thread or the bottom thread is installed.

切線刀或拉線刀16用於切斷夾緊線。拉線刀可以在圖4所示的原始位置和圖2所示的線檢測位置之間圍繞垂直的擺動軸線擺動。例如經由氣動驅動器來驅動切線刀16的擺動運動。也可以使用其他驅動機構。The thread cutter or the thread pulling knife 16 is used to cut the clamping thread. The wire pulling knife can swing around a vertical swing axis between the original position shown in FIG. 4 and the wire detection position shown in FIG. 2. The oscillating movement of the thread cutter 16 is driven, for example, via a pneumatic drive. Other drive mechanisms can also be used.

在根據圖2的視圖中，拉線刀16具有鐮刀狀的基本形狀，其自由端在原始位置中圍繞夾緊器14的梭殼伸展。In the view according to FIG. 2, the thread-pulling knife 16 has a sickle-like basic shape, the free end of which extends around the bobbin case of the gripper 14 in the original position.

拉線刀16的刀面17(參見圖10)與固定於殼體上的割線定刀19的定刀面18的切割邊緣配合，用於線切割。定刀19大致具有被磨削的長方體形狀，其具有用於固定在殼體上的止動銷20的止動凹槽19a，來設定定刀19擺動支承的止動定刀位置19 1, 19 2(參見圖9)，該擺動支承圍繞擺動軸線21在仍待描述的定刀容納部中進行。此外，定刀19具有用於軸承銷22的穿通孔(參見圖8)。軸承銷22預先確定定刀容納部中定刀19擺動支承的擺動軸線21。 The knife surface 17 of the thread-pulling knife 16 (see FIG. 10) is matched with the cutting edge of the fixed knife surface 18 of the secant fixed knife 19 fixed on the housing for wire cutting. The fixed knife 19 generally has a rectangular parallelepiped shape to be ground, and has a stop groove 19a for a stop pin 20 fixed to the housing to set the stop fixed knife position 19 1 , 19 2 of the fixed knife 19 swinging support. (Refer to FIG. 9), the swing support is carried out around the swing axis 21 in the fixed knife receptacle still to be described. In addition, the fixed knife 19 has a through hole for the bearing pin 22 (see FIG. 8). The bearing pin 22 predetermines the swing axis 21 on which the fixed knife 19 is swingably supported in the fixed knife accommodation portion.

用於定刀19的定刀容納部23是定刀容納保持件24的一部分。定刀容納保持件經由定刀座保持件25固定在縫紉機1的殼體6上。The fixed knife receiving portion 23 for the fixed knife 19 is a part of the fixed knife receiving holder 24. The fixed knife accommodating holder is fixed to the housing 6 of the sewing machine 1 via the fixed knife seat holder 25.

定刀容納保持件24相對於定刀座保持件25位置可調節地安裝。The fixed knife accommodating and retaining member 24 is installed in an adjustable position relative to the fixed knife seat retaining member 25.

固定於殼體上的定刀容納部23中的定刀19在第一止動定刀位置(參見圖9中的位置19 1)和與之對應的第二止動定刀位置(參見圖9中的位置19 2)之間的位置區域中關於切割定刀位置(例如參見圖10中定刀19的位置)是連續可調節並可固定的。通過定刀19圍繞擺動軸線21在擺動範圍內擺動進行這種連續調節，該擺動範圍由所述止動凹槽19a在圍繞擺動軸線21的圓周方向上進行預先確定。在止動定刀位置19 1中，止動凹槽19a的限制壁碰撞止動銷20；並且在第二止動定刀位置19 2中，對側止動凹槽19a的限制壁碰撞止動銷20。軸承銷22穿過定刀19的穿通孔或鑽孔26用以擺動支承。 The fixed knife 19 in the fixed knife accommodating portion 23 fixed on the housing is at the first stop fixed knife position (see position 19 1 in FIG. 9) and the corresponding second stop fixed knife position (see FIG. 9). The position of the fixed knife (for example, see the position of the fixed knife 19 in FIG. 10) in the position area between the positions 19 2 ) is continuously adjustable and fixed. This continuous adjustment is performed by the fixed knife 19 swinging around the swing axis 21 within a swing range that is predetermined by the stop groove 19 a in the circumferential direction around the swing axis 21. In the fixed knife stop position 19 1 , the restriction wall of the stop groove 19a collides with the stop pin 20; and in the second fixed knife stop position 19 2 , the restriction wall of the opposite stop groove 19a collides with the stop pin 20 . The bearing pin 22 passes through the through hole or drilled hole 26 of the fixed knife 19 for swing support.

線上切割過程中，當定刀19與切線刀16配合時，進行連續調節。對此，定刀19浮動地安裝在定刀容納部23中。During the on-line cutting process, when the fixed knife 19 and the thread cutting knife 16 cooperate, continuous adjustment is performed. In this regard, the fixed knife 19 is floatingly mounted in the fixed knife receiving portion 23.

另外，定刀容納部23中的定刀19可以借助固定夾緊裝置(圖中未示出)在極限定刀位置19 1和19 2之間以期望的定刀位置進行固定。然後，當切線刀16的切割面和定刀19的切割面關於切割配合地彼此接觸時，這種固定可以在初次調節定刀19時進行。然後，在定刀19的相對切割位置中，可以將其固定在定刀容納部23中。這種固定不是強制性的。 Further, the fixed blade receiving portion 23 of the fixed blade 19 may be secured by means of a clamping device (not shown) is fixed between the fixed knife extreme positions 191 and 192 in a desired position fixed knife. Then, when the cutting surface of the thread cutting knife 16 and the cutting surface of the fixed knife 19 are in contact with each other with respect to cutting, this fixing can be performed when the fixed knife 19 is adjusted for the first time. Then, in the relative cutting position of the fixed knife 19, it can be fixed in the fixed knife receiving portion 23. This fixation is not mandatory.

夾線彈簧27經由螺釘28固定在定刀容納保持件24上。在切線刀16的原始位置中(參見圖4)，夾線彈簧27與切線刀16配合，用以夾緊和保持所切割的線、即面線和底線。The wire clamping spring 27 is fixed to the fixed knife accommodating holder 24 via a screw 28. In the original position of the thread cutter 16 (see FIG. 4), the thread clamping spring 27 cooperates with the thread cutter 16 to clamp and hold the cut thread, that is, the upper thread and the bottom thread.

定刀19可以設計成可逆式定刀，也就是說可以構造為，使得其能夠在定刀容納部中的不同方向使用，其中定刀的各個其他切割邊緣與切線刀16的刀面配合用以線切割。定刀19除了具有一方面用於軸承銷22而另一方面用於止動銷20的凹槽之外，定刀19原則上能夠如EP 1 992 726 A1中所描述的那樣構造。而且例如WO 95/19245 A1或DE 36 21 785 A1中所公開的構造那樣，定刀可以在不同方向上使用。The fixed knife 19 can be designed as a reversible fixed knife, that is to say, it can be configured so that it can be used in different directions in the fixed knife receiving portion, wherein each other cutting edge of the fixed knife cooperates with the knife surface of the thread cutting knife 16 Wire cutting. The fixed knife 19 can in principle be constructed as described in EP 1 992 726 A1, except that it has a groove for the bearing pin 22 on the one hand and the stop pin 20 on the other hand. Moreover, for example, the structure disclosed in WO 95/19245 A1 or DE 36 21 785 A1, the fixed knife can be used in different directions.

在借助縫紉機1縫線之後，操作切線刀，其中首先將其從原始位置轉移至線檢測位置，接著在檢測完面線和底線之後，將其再次轉移至原始位置。在此，通過刀面17與定刀19的配合進行線切割，並且之後將切割的線限定地保持在切線刀16和夾線彈簧27之間。After sewing the thread with the sewing machine 1, the thread cutter is operated, in which it is first transferred from the original position to the thread detection position, and then after detecting the upper thread and the bottom thread, it is transferred to the original position again. Here, the wire cutting is performed by the cooperation of the knife surface 17 and the fixed knife 19, and then the cut wire is held between the wire cutter 16 and the wire clamping spring 27 in a defined manner.

縫紉機也可以是以滑輪形式輸送縫紉材料的縫紉機。縫紉機1可以設計為柱式縫紉機。縫紉機1也可以設計為平臺式或自由臂式縫紉機。所描述的切線刀/定刀的構造除了應用於以附圖為例的臥式縫紉機，還能夠應用於立式縫紉機，對於該立式縫紉機，底板是豎直伸展而非水平伸展，並且針跡形成工具相應地傾斜90°。The sewing machine may also be a sewing machine that conveys sewing materials in the form of a pulley. The sewing machine 1 can be designed as a column sewing machine. The sewing machine 1 can also be designed as a platform type or a free arm type sewing machine. The described thread cutter/fixed knife structure is not only applied to the horizontal sewing machine shown in the figure, but also can be applied to the vertical sewing machine. For this vertical sewing machine, the bottom plate extends vertically instead of horizontally, and the stitches The forming tool is correspondingly inclined by 90°.
