Description. [Patent Document 1] Japanese Laid-Open Patent Publication No. Hei No. 99571 [Patent Document 2] Japanese Patent Laid-Open Publication No. Hei 7 No. 2963 No. 1 [Ming Nei Po.] The invention discloses a problem to be solved by the invention. In any of the above-described fasteners, the adjustment of the stitch pitch of the width of the buttonhole is determined by the engagement position of the feed wheel of the arcuate guide. When the card 15 is retracted from the rocking fulcrum of each of the rocking members, the pitch is increased, and the pitch is reduced as the distance is close. Therefore, it is necessary to correspond to the button having a large interval between the buckle holes, and the width of the engagement position is designed to be large. Therefore, it is necessary to set a stroke of the arc-shaped guide member of the rocking member. However, in the stapler 200 of the patent document shown in Fig. 11, since the arc-shaped guide period of the rocking member 2〇1 of the sewing method selecting mechanism 2〇Q is different, it cannot be ensured. Sufficient to move the component T of the arcuate guide 2〇8 of the member 2〇1. On the other hand, when the stroke of the arcuate guide 208 of the rocking member 201 is ensured, the arcuate guide 208 of the rocking member 201 is extended. Further, the stroke of the arcuate guide 2〇9 of the rocking member 202 is limited, and the 200912073 rocking members 201, 202 cannot both ensure the problem of the stroke of the arcuate guides 208, 209. With respect to the above problem, in the button fastening machine 200A of Patent Document 2 shown in Fig. 12, by arranging the respective groove cams 2〇3A, 204A at both end portions of the shaft 205, 5, the rocking members 201A, 202A can be made. The distance between the pivot points is larger than that of the stapler of Patent Document 1, and the stroke of the arc-shaped guides 208A, 209A is ensured. However, in the button sewing machine 200A of Patent Document 2, as shown in Figs. 13 and 14, the following problems occur. 10 that the order of the underpins is as shown in Figure 13(a) and Figure 13(b).
開始位置（第1針）及結束位置（第16針）在兩個縫法並不同。 因此，縫法選擇機構200A之溝凸輪203A，204A之溝設置成 結束位置（第16針）後，鈕扣保持機構移動至開始位置（第j 針）之位置，以於1個釘扣結束後，進行下個釘扣。以溝凸 15輪203A，204A搖動之搖動構件2〇ia，202A從結束位置（第 16針)移動至開始位置（第1針）時，如第14圖所示，各圓弧狀 導件208A，209A錯開。此時，對釘扣之縫合要切換第13(a) 圖之縫法與第13(b)圖之缝法時，使送料輪2〇6可沿圓弧狀導 件208A，209A移動之時間僅為在搖動構件2〇1A ，202A之 20圓弧狀導件208A，209A沿著相同圓周上之時間。 因而，釘扣之結束及開始時，只要溝凸輪203A ，204A 之停止位置稍微偏離，搖動構件2〇1A，2〇2A之圓弧狀導件 208A ’ 209A便大幅偏離，而無法傳遞送料輪施。是故， 無法確實地進行縫法之切換。 200912073 本發明鑑於上述問題點，提供一種藉確保足夠之對應 紐扣孔間隔之間距調整之寬度，可輕易且针地進行縫法 之切換之#r扣機。 用以欲解決問題之手段 10 15 申請專利範圍第1項之發明係一種釘扣機包含有使缝 十在預疋之位置上下移動，以形成針跡之針跡形成機構 (17 ’ 19)，一面保持鈕扣，—面可相對於縫針之上下移動位 置於水平方向移動之紐扣保持機構(4〇);使前述叙扣保持機 構進行2種不同之送料運動之2個凸輪部(54，55);在縫合叙 扣之預定針數’使前述針跡形成機構及前述兩凸輪部之動 作停止之停止機構(30);與前述紐扣保持機構連結，而可旋 動操作之縫法選擇機構(58);各自獨立地卡合於前幻個凸 輪料之-者，同時，隨動於卡合之凸輪而搖動，藉此， 可於前述姊保持機構產生送料運動之2個搖動構件⑼， 外及形成沿前述縫法選擇機構之旋鱗徑之圓弧狀，八 別設於前述搖動構件之圓弧狀引導構件(my。釘^ 進行釘扣勒，該釘扣_係使前述2個圓弧狀料财以 相互相對之狀態，延伸設置於同—_上，以前述縫法選 擇機構之操作進彳了切換’使前述縫㈣擇機構卡合」 圓孤狀引導構件，藉此，前述紐扣保持機構對應於任—I 選擇之凸輪部而移動。該釘扣機之特徵在於前述 在以前述縫法選擇機構之操作選擇任一 —。 形狀係形成為使第1針及最後1針分別於同—钮# ' 兩 根據申請專利範圍第1項之發明:由於在：::第 20 200912073 !針進行下狀孔與在最㈣淺行下針之孔在二種縫法， 例如近似U字縫與X字縫—致，故姊縫合完畢後，停止釘 扣機時’2個搖動構件之圓弧狀導件之各前端部之前後移動 方向經常-致。因而，各導件呈在其搖動方向於同一位置 5排列之狀態，而在域釘扣之開始前後，在各導件呈沿同一 圓周上排列之狀態，亦即最適合縫法選擇機構從其中一導 件傳遞至另-導件之狀態，即使各導件之停止位置偏離， 亦不致如習知般導件之前端於不同方向偏離而於相同之 方向偏離，故可經常確實且輕易地切換縫法選擇機構。 1〇 又*縫法選擇機構從其中一導件傳遞至另一導件時， :減低縫法選擇機構撞擊另—導件，而於縫法選擇機構及各 導件產生破損之可紐，可提供可#錢高之釘扣機。 【資方式】 用以實施發明之最佳形態 15 (實施形態之全體結構） 以下，依第丨圖至第丨0圖，就本發明實施形態之釘扣機 訓乍朗。第丨_本案發明—實麵態之釘扣卿〇之側 面圖，第2圖係立體圖。 釘扣機100包含⑽納或保持釘扣機各結構之機架 20 20，作為各結構之驅動源之圖中未示之機體馬達，將機體 馬達之輸出轉矩傳達至各結構之圖中未示之主抽，切換從 機體馬達至主軸之動力傳達之連接與切斷之離合器機構 25 ’由使縫針17上下移動之上下移動機構％及與縫針17 — 同運作，形成環縫之針跡之旋轉式線鉤19(參照第4圖）之圖 200912073 之==形成機構，保持縫合於被縫製物 物/ 扣保持機構4Q，縫製時將縫針斑缝合 位，移動機構5°，用以設定縫合物之鏠合所需之 2並㈣停止機構」之針數調節機構30。即，停土機 構在縫合鈕扣之狀魏，㈣述針㈣錢構及後述凸 輪部54，55之動作停止。 (機架） 如第1圖及第2圖所示，機架2〇全體形成約口字形，具 10 有構成其下部之機床部2卜從機床部21之—端部直立設置 之直立部22，從直立部22於與機床部21相同之方向延伸之 臂部23。 另，在以下之說明中，令機床部21之長向為γ軸方向， 與Υ轴方向垂直相交，縫針17進行上下移動之方向為2轴方 向，於Υ軸方向及Ζ軸方向垂直相交之方向為乂軸方向。 15 (各輛之連結） 在機床部21内，主軸可旋轉地沿X軸方向配設，從機體 馬達藉由離合器機構25，進行旋轉驅動。 又，在機床部21内，線鉤機構之線鉤軸可旋轉地沿Υ 軸方向配設’從主軸藉由螺旋齒輪以與主軸相等之速度進 20行旋轉驅動。 在機床部21内’針數調節機構30之減速軸31可旋轉地 沿X軸方向配設，以安裝於線鉤軸之直立部22側端部之禍 輪，以預定之減速比，賦與旋轉驅動力。 在機床部21内，連動軸34沿X軸方向可旋轉地配設’傅 11 200912073 使針數調節機構30與離合器機構25連動。 (針數調節機構） 在第3圖中，僅顯示設置於機床部21之針數調節機構3〇。 如該等圖所示，針數調節機構30具有安裝於線鉤軸之 5圖中中未示之蝸輪，具有與蝸輪咬合之平齒輪，對主軸以 預定減速比進行旋轉驅動之前述減速軸31，設置於減速軸 31之一端部之約呈圓板狀之板凸輪32，用以謀求與離合器 機構25之連動之連動軸34、基端部固定支撐於連動軸％之 一端部，同時’搖動端部卡合於板凸輪35外周之調節腕％、 10將調節腕33朝向板凸輪32按壓之圖中未示之彈簧33a。 上述針數調節機構3〇之蝸輪與減速軸之平齒輪可更換 為齒距及齒數不同之其他齒輪，藉此，可調節減速軸之減 速比。減速軸31依用以縫合缝合物之針數，進行適當選擇。 舉例言之，縫合物為具有4個穿線孔之鈕扣，每2個孔以8針 15之針數進行縫合時，由於需總計16針之針數，故使用減速 比為16之蜗輪及平齒輪。 即’減速軸31對主轴以藉齒輪之選擇設定之減速比進 行旋轉驅動。 板凸輪32固定保持於減速軸31，隨之進行旋轉，同時， 20其形狀約呈圓形，於其外周之一部份形成凹部32a。 調節腕33之搖動端部被按壓至板凸輪32之外周，僅於 方疋轉之板凸輪32之凹部323時，朝板凸輪32之中心側進行播 動。 12The start position (1st stitch) and the end position (16th stitch) differ in the two stitching methods. Therefore, after the groove of the groove cams 203A, 204A of the sewing method selection mechanism 200A is set to the end position (16th stitch), the button holding mechanism is moved to the position of the start position (j-th needle) so that after one stapling is completed, Carry out the next button. When the rocking members 2〇ia, 202A which are swung by the groove 15 wheels 203A, 204A are moved from the end position (16th needle) to the start position (first stitch), as shown in Fig. 14, each of the arc-shaped guides 208A , 209A staggered. At this time, when the sewing of the stud is to be switched between the sewing method of the 13th (a) and the sewing method of the 13th (b), the timing of the feeding wheel 2〇6 being movable along the arc-shaped guides 208A, 209A It is only the time along the same circumference of the arcuate guides 208A, 209A of the rocking members 2〇1A, 202A. Therefore, at the end and the beginning of the buckle, as long as the stop positions of the groove cams 203A, 204A are slightly deviated, the arc-shaped guides 208A ' 209A of the rocking members 2 〇 1A, 2 〇 2A are largely deviated, and the feed wheel can not be transmitted. . Therefore, it is impossible to switch the sewing method surely. In view of the above problems, the present invention provides a #r button machine which can easily and pin-and-tap the sewing method by ensuring a sufficient width for adjusting the interval between the corresponding buttonhole intervals. Means for Solving the Problem 10 15 The invention of claim 1 is a stapler comprising a stitch forming mechanism (17' 19) for moving the slit ten up and down at a pre-twisted position to form a stitch, a button holding mechanism (4〇) that can move in a horizontal direction with respect to the upper and lower movement positions of the needle; and two cam portions (54, 55) that perform the two different feeding movements by the aforementioned buckle holding mechanism a stop mechanism (30) for stopping the operation of the stitch forming mechanism and the two cam portions in the predetermined stitch number of the stitching; a sewing method selecting mechanism that is coupled to the button holding mechanism and rotatable Each of them is independently engaged with the front phantom cam material, and at the same time, it is rocked by the engaging cam, whereby the two rocking members (9) capable of generating the feeding motion in the 姊 holding mechanism are externally Forming an arc shape along the spiral diameter of the slit selection mechanism, and setting the arc-shaped guiding member of the rocking member (my nail) to perform a pinning, and the fastening button is for the two arcs Expanded in the state of mutual relatives In the same -_, the operation of the sewing method is carried out by switching the 'sewing of the slit (four) mechanism to the circular orphan guide member, whereby the button holding mechanism corresponds to the cam portion selected by -I And the buttoning machine is characterized in that any one of the foregoing operations is selected by the operation of the slit selection mechanism. The shape is formed such that the first stitch and the last stitch are respectively in the same button #' according to the patent application scope. The invention of 1 item: Because in::: 20th 200912073! The needle is made into the lower hole and the hole in the most (four) shallow line is in two kinds of sewing methods, for example, the U-shaped seam and the X-shaped seam are caused, so the suture is sutured. After the completion of the stapling machine, the front end portions of the arc-shaped guide members of the two rocking members are often moved in the front and rear directions. Therefore, the guide members are arranged in the same position 5 in the rocking direction thereof. Before and after the start of the field fastener, the guide members are arranged along the same circumference, that is, the most suitable state for the sewing method to be transmitted from one of the guide members to the other guide member, even if the stop positions of the guide members are stopped. Deviate, not as conventional as the guide Different directions deviate and deviate in the same direction, so the sewing method selection mechanism can be switched frequently and easily. 1〇 and *Sewing selection mechanism is transmitted from one of the guide members to the other guide member: Reduce the sewing method selection mechanism Impacting the other-guide, and the sewing method and the guides are damaged, and the button can be provided.

That is, the earth-moving mechanism is in the shape of the sewing button, (4) the needle (four) money structure and the operation of the cam portions 54, 55 described later are stopped. (Rack) As shown in Figs. 1 and 2, the frame 2 is formed in a square shape as a whole, and the machine unit 2 having the lower portion thereof has an upright portion 22 which is erected from the end portion of the machine unit 21 The arm portion 23 extends from the upright portion 22 in the same direction as the machine tool portion 21. In the following description, the longitudinal direction of the machine tool unit 21 is the γ-axis direction and perpendicular to the Υ-axis direction, and the direction in which the needle 17 moves up and down is the two-axis direction, and the vertical direction intersects the Υ-axis direction and the Ζ-axis direction. The direction is the x-axis direction. 15 (connection of each vehicle) In the machine unit 21, the main shaft is rotatably disposed in the X-axis direction, and is driven to rotate from the machine motor by the clutch mechanism 25. Further, in the machine unit portion 21, the wire hook shaft of the wire hook mechanism is rotatably disposed in the z-axis direction. The spindle is rotationally driven by the helical gear at a speed equal to the spindle speed. In the machine tool unit 21, the deceleration shaft 31 of the needle number adjustment mechanism 30 is rotatably disposed in the X-axis direction to be attached to the end of the side of the upright portion 22 of the hook-and-loop shaft, and is given a predetermined reduction ratio. Rotational driving force. In the machine unit 21, the interlocking shaft 34 is rotatably disposed in the X-axis direction.

(Needle Number Adjustment Mechanism) In the third diagram, only the stitch number adjustment mechanism 3A provided in the machine tool unit 21 is displayed. As shown in the figures, the needle number adjusting mechanism 30 has a worm wheel (not shown) attached to the wire hook shaft, and has a spur gear that meshes with the worm wheel, and the above-described speed reducing shaft 31 that rotationally drives the spindle at a predetermined reduction ratio. a disk-shaped plate cam 32 disposed at one end of the deceleration shaft 31 for interlocking with the clutch mechanism 25, and the base end portion is fixedly supported at one end of the interlocking shaft % while being 'shaking The adjustment arms %, 10 whose ends are engaged with the outer periphery of the plate cam 35 press the adjustment arm 33 toward the plate cam 32, and the spring 33a (not shown) is shown. The spur gear of the worm wheel and the reduction shaft of the needle number adjusting mechanism 3 can be replaced with another gear having a different pitch and number of teeth, whereby the speed reduction ratio of the speed reduction shaft can be adjusted. The deceleration shaft 31 is appropriately selected depending on the number of stitches for suturing the suture. For example, the suture is a button with four threading holes. When each of the two holes is stitched with 8 stitches of 15 stitches, since a total of 16 stitches is required, a worm gear and a spur gear with a reduction ratio of 16 are used. . That is, the deceleration shaft 31 rotationally drives the main shaft at a reduction ratio set by the selection of the gear. The plate cam 32 is fixedly held by the deceleration shaft 31, and is rotated therewith. At the same time, the shape of the plate cam 32 is approximately circular, and a recess 32a is formed in one of the outer circumferences. The rocking end portion of the adjustment arm 33 is pressed to the outer circumference of the plate cam 32, and is played only toward the center side of the plate cam 32 when the concave portion 323 of the plate cam 32 is rotated. 12

The deceleration sleeve 31 rotates the main shaft at a reduction ratio of 16, so that the 16-pin rotation is performed once, and every 16 stitches are stopped. Therefore, the stitch adjustment mechanism 3 having the plate cam 32 functions as a "stop mechanism". Further, in the above embodiment, when the four-hole button is sewn, the plate cam 323 is rotated one turn, and the stitching of one button is completed, so that the recess 32a is provided at the outer periphery of the plate cam 32. The number of the recesses 32a of the plate cam 32 is based on the relationship between the amount of rotation of the speed reduction shaft 31 and the number of stitches required to sewn the button, and is of course not limited to the above embodiment. In other words, the reduction ratio of the deceleration shaft 31 may be an integral multiple of the number of stitches required for sewing the button, and the recess 32a having the same number as the integral multiple may be provided at a uniform interval. (Clutch mechanism) as shown in Fig. 1 to As shown in Fig. 3, the clutch mechanism 25 is connected to the stitch number adjusting mechanism 30 of the number of stitches set by 15 in the count, and the connection and disconnection between the driving force of the body motor and the main shaft are switched, and the motor is driven by the body motor. The actuating pulley 26, which is not shown, can be driven to rotate and drive the driven pulley 27, and the driven pulley 27 can be moved up and down with respect to the active sliding (10), and the front end portion can be swung up and down to switch the contact and separation of the driven pulley 27 to switch from the contact state. In the state of separation 20, the brake lever of the driven pulley 27 of the inertia rotation is stopped. The switching lever 28 and the brake lever 29 are fixedly supported by the interlocking pump 34, and are rocked around the interlocking shaft 34. 13 200912073

When the adjustment arm 33 and the plate cam 32 are lowered to the lower position 'when the power of the β wheel 27 is swung from the recess 32a, the adjustment arm 33 is disengaged from the recess, and the adjustment arm 33 is engaged with the recess 32a. Communicated from the active pulley hemp. The shaft of the brake lever 29 is pivoted about the linkage shaft 34, and the rocking end portion is moved up and down, and is lowered by sliding to contact the outer peripheral surface of the driven pulley 27. The driven pulley 27 is fixed to the main shaft, and the power from the active pulley is transmitted to the main shaft by the driven pulley 27. When the fitting portion is formed at a predetermined position on the outer circumference of the driven pulley 27, and the fitting portion of the driven driven pulley 27 is engaged with the front end portion of the brake lever 29, the brake 15 acts on the driven pulley 27. Then, the switching lever 28 and the brake lever 29 are manually operated to activate the pedal so that the respective rocking ends are swung upward. In other words, when the body motor is started, in the state in which the end portion of the adjustment arm 33 of the stitch number adjusting mechanism 30 is fitted into the concave portion 323 of the plate cam 32, the power cannot be transmitted to the main shaft, and the pedal is artificially transmitted. When the power transmission to the main shaft is performed, since the deceleration shaft also starts to rotate from the main shaft by the wire hook shaft, the state in which the adjustment arm 33 is disengaged from the concave portion 32a of the plate cam 32 is maintained even if the foot is separated from the start pedal. When the spindle performs the rotation of the set number of needles, since the adjustment arm 33 14 200912073 is slidably locked to the recess 32a of the plate cam 32, the power is cut off from the active pulley 26 to the position: the power of the day: the special. Then, the driven pulley 27 is inertly rotated, and when the fitting portion of the engagement portion reaches the front end portion of the contact lever 29, the front end (stitch formation is) acts to stop the inertial rotation of the driven pulley 27 and the main shaft. Up and down I: shape, the mechanism upper and lower moving mechanism 35 has a figure h along the axis in the upright portion 22 while 'the eccentric cam (not shown) is connected to the main end portion, and the rod body of the el is maintained At the same time, the needle 17' is held in front of the arm portion 23 to be rockable: a needle bar 36 that can be moved up and down, and inside the arm portion 23, the wrist 37 is rocked. The other end and the upper end are connected to the end of the rocking arm 37, and the rocking arm 37 is connected to the needle: the state in which the upper and lower movements are displaced, and the upper and lower sides of the main body are moved up and down by the same period of the main shaft. The 15 needle plus the main (4) zone power is transmitted to the needle bar 36 by rocking the wrist 37, and the slit 7 is moved up and down in synchronization with the rotation of the spindle. In Fig. 4, the needle plate 18 is omitted. The thread hook of the stitch forming mechanism The mechanism has a wire hook shaft in front of the machine tool portion 21, and a wire hook 19 supported on the lower side of the needle plate 18 on the lower side of the needle plate 18. The sharp pointed tip has a stitching pin 17 which is lowered from below the needle plate 18 The brother of the line is a big master, when the rotation of the shaft is full rotation, 'capture the suture, and move it to the bottom, and the tip of the seam ^ is located at the top _ 'When the direction is again upward, then when the line is twisted, 'by the tip The needle stitch of the last stitch of the stitching catches the stitch ring, and the reverse S' allows the next loop to penetrate the cover to perform the action, and the single-line loop can be performed. 15 200912073 (Button holding mechanism) As shown in Figs. 1 and 2, the button holding mechanism 4 for holding the button extends on the upper surface of the machine tool portion 21 in the γ-axis direction, and supports the front end portion of the machine tool portion 21 at its front end portion. Move freely along the XY plane. As shown in Fig. 5, the button holding mechanism 40 has a spring extending toward the distal end side, which is a pair of gripping claws 41, 41 and pressing the gripping claws 41, 41 in the direction in which they are close to each other. When the button B is sewn, the button B is held in a state of being sandwiched between the respective holding claws 41, 41. Further, the gripping claws 41, 41 are different depending on the type of the suture (the size of the button or the like) 10 and the configuration of the distal end portion. In addition, the buttoning machine 100 forms a hole of the four-hole button at the four vertex positions of the square to form a stitching object, and the button holding mechanism is in the position of each of the clamping claws of the button holding position. The two sides of the square in which the holes are formed are parallel in the X-axis direction, and the other two sides hold the buttons in the direction 15 in which the γ-axis direction is parallel. As shown in the figure, the long hole 2a is provided in the bottom plate of the button holding mechanism, and the wheel 43 can be snapped to the long hole. The wheel is set to a predetermined position in the rack. 20, before and after the moving mechanism 5G, the moving mechanism communicates before and after the movement is long; the wheel 43 slides, the bottom plate 42 moves back and forth in the direction substantially along the γ-axis direction, and the right and left movement mechanism of the moving mechanism 5G conveys the left and right movement to the wheel It is said that the material of the bottom correction 2 and b move back and forth in the direction substantially along the X-axis direction.

the buckle holding mechanism 4. TM on mobile, mobile agencies. (Left and right moving mechanism) As shown in Fig. 6, the right and left moving mechanism has a cam groove corresponding to the stitch formation of the stitching as a "cam mechanism" in terms of the movement of the button 10 holding mechanism 40 substantially in the X-axis direction. The right and left movement groove cams 51 are pivoted by the cam groove shape of the right and left movement groove cams 51, and the bases of the swinging arm 52 and the buckle holding mechanism 4 are connected to move substantially in the direction of the x-axis direction. It is transmitted to the right and left movement transmitting member ^ of the face button holding mechanism 4'. 15 S_52 lower material, the roller material roller roller shaft 5 is the shaft support. The roller of the rocking arm 52 is engaged with the cam groove of the right and left movement groove cam. The roller moves back and forth in the direction of the yaw axis direction according to the shape of the cam groove, and the front end of the wrist 52 is rocked substantially along the χ axis. The direction of the direction is swung. One end of the left and right movement transmitting member 53 is coupled to the front end of the rocking arm 52, and the other end is coupled to the bottom plate 42 of the button holding mechanism 40. Thereby, the shaft 43a of the wheel 43 of the button holding mechanism 40 is used. For the rotating shaft, the button holding mechanism 4 is rocked left and right. The other end of the left and right movement transmitting member 53 and the bottom plate 42 of the button holding mechanism 4 can be changed and adjusted, whereby the left and right rocking strokes can be adjusted. When the bottom plate 42 is connected to the other end of the left and right movement transmission mechanism 17 200912073, the left and right movement strokes are reduced, and the bottom plate 42 is connected to the other end of the left and right movement member brothers at the position close to the shaft 43a of the wheel 43. The left and right movement strokes are increased. The relationship between the shape of the groove provided in the right and left movement groove cams 51 and the movement of the button retaining mechanism 40 will be described later. (Backward movement mechanism) 10 1 5 20 As shown in Fig. 6, the 'forward and backward movement mechanism has two forward and backward movement groove cams 54' 55 which are "cam portions" and "cam mechanisms" corresponding to the U-shaped seam and the X-shaped slit of the buckle. The shape of the cam groove provided in the two front and rear moving groove cams 54, 55 is pivotally supported by the rocking fulcrum shaft 56d, 57d of the machine tool portion 21, and the two rocking members 56, 57 of the middle to the rocking are switchably selected. The U-stitch and X-stitch sewing method selection mechanism 58 supports the handsome storage mechanism 4G so as to move the support members 59a' to 59b forward and backward in a direction substantially moving in the Y-axis direction. The two rocking members %' 57 respectively have an arc-shaped guide thinner, 57a, and the front ends of the arc-shaped guides 56a' 57a are opposed to each other. The two front-rear movement groove cams are approximate U-slot groove cams 54 having cam grooves formed corresponding to the stitches of the approximate u-slots, and have the groove grooves for the cam grooves formed by the stitches corresponding to the stitches of the word slits. 55 composition. Therefore, the front and rear feed cams 54' 55 function as cam portions, causing the button holding mechanism to perform a different feeding motion. The two-money moving material cams 54, 55 and the left and right moving grooving wheels 51 are concentric and fixedly cut to the deceleration shaft, and the disc-shaped cams are formed on the circumferential surface to guide the rollers of the jug χ axis square groove. The groove cams 51, 54' 55 are fixedly supported on the coaxial side for synchronization. That is, the movement of the groove from the first stitch to the last stitch of the sewing machine 18 200912073. The movement of each hole of the 胄 position drop is performed simultaneously at each stitch. The two front and rear moving groove cams 54, 55 and the left and right moving groove cams are rotated at a speed to rotate a period of time during the formation of a predetermined number of stitches. ...to the bottom of the two rocking members 56, 57, respectively, roller rollers (refer to Figure 9), the rollers 56c, 57c to feed the cam roller, and the branch. The roller 56e of the member 56 is engaged with the cam groove of the grooving groove cam 54, the deceleration shaft 31 is rotated, and the U-stitching cam 54 is rotated, and the roller 56 of the rocking member 56 is close to the splicing cam 54. When the cam groove is rocked, the rocking end portion of the circular recording guide is rocked in a direction substantially along the γ-axis direction. The roller 57 of the rocking member 57 (the cam groove of the slanting groove groove cam is engaged, the deceleration shaft 31 is suspected to rotate, the stencil groove is rotated by the groove cam 55, and the roller π of the rocking member π is used for the groove groove cam When the cam groove of the 55 is swung, the rocking end portion of the arcuate guide 57a of the rocking member 57 is rocked in the direction of the substantially mandrel direction. Thus, the two rocking members 56, 57 and the two cams 54, 55 are 15 The two are engaged with each other independently, (4), followed by the cam of the engagement, whereby the feeding mechanism can be generated by the button holding mechanism 40. The sewing method 58 has an arc-shaped guide, % The grounding wheel & feeding wheel 58a supports the wheel to be a rotatable feeding adjustment rod 58b. The rotating fulcrum of the material adjusting rod 58b is coupled with two front and rear moving support members, the end of 0 59b. The feeding adjustment rod 5, the front and rear moving branch member members are connected to the button holding mechanism 40. Thereby, the sewing method selecting mechanism 58 is fixed to the predetermined position of the machine tool portion 21 and then moves the other end of the supporting member 59a as a rocking fulcrum. One of the arcuate guides 56a, 57a conveys a substantial /cr Y The rocking motion in the direction of the axis direction is transmitted to the button holding mechanism. The slit 19 200912073 is connected to the button holding mechanism 4〇, and can be rotated. By the rotation of the feed adjusting lever 58b, the feeding wheel 58a can be moved along The arc-shaped guides 56a, 57a are rotated. At this time, the distance between the feed wheel 58a and each of the rocking members %, π, the rocking fulcrum axes 56d, 57d is changed. Thereby, the circle of the members 56, 57 is shaken from each The orphan guides 56a, 57a are changed in the movement stroke before being conveyed to the button holding mechanism 40 by the sewing method selection mechanism. The feed wheel 58a and the arc-shaped guide members 56a, 57a are close to the pivoting fulcrum thereof. When the positions of the shafts 56d, 57d are engaged, the front and rear miscellaneous materials are conveyed from the rocking member having the arc-shaped guide. Further, any of the #补轮58a and the arc-shaped guides 1056a, 57a are When the position away from the pivot point is engaged, the movement stroke is large before the conveyance of the arc-shaped guide member. That is, if the feed adjustment lever 58b is rotated, the feed roller 58a and the arc-shaped guide are adjusted. One position of the engagement, the front and rear movement lines can be adjusted Further, by rotating the feed adjusting lever 58b, the arc-shaped guide pool 57a of the feed roller 58a can be switched. For example, the tearing from the feed roller and the arc-shaped guide 56a are engaged. The state of the U-shaped slit is switched to the U-shaped slit, and the feed adjusting lever 58b is operated to guide the feed 58 wheel a from the arc-shaped guide 56a to the arc-shaped guide 57a. Of course, the opposite operation can be performed. The switchable feed wheel 58a is engaged with any one of the arc-shaped guides 56a, 57a. That is, by using the feed adjustment lever 58b, it is possible to select either one of the approximate ϋ-stitch and the splicing. The button retains the movement mode of the mechanism 4〇. (Approximating the U-slot and the position of the needle under the sewed seam) Next, the U-stitch and the X-stitch are approximated to the position of the needle under the button and the groove cam 51 for the left and right movement, and the groove cam 54 and the 缝 groove are approximated. Word groove groove convex 20 200912073 The relationship between the groove shape of the wheel 55 is described in detail. Fig. 7(4) is a diagram showing the order of the needles below the U-slot of the button B, and the figure 7(8) shows an illustration of the sequence of the needles under the X-slot. In addition, the figure 丨~ of the figure 7 indicates the gaze under the stitch of the button. Fig. 8 is a diagram showing the shape of the groove of the right and left movement groove corresponding to the needle order in Fig. 7, which approximates the groove shape of the u-slot groove cam 5qx word (four) groove cam 55. The eighth (8)_ shows the groove shape of the left and right moving material cams, the first figure shows the groove shape of the U-shaped groove groove cam 54, and the eighth figure (e) shows the groove shape of the X-shaped groove groove cam 55. In addition, if the figure is the same as the figure s(4), and the arc-shaped guides that are swayed by the respective groove cams 54, 55, the direction of extension is opposite, the approximate u-slot groove cam 54 is used. The respective shapes of the slit groove cams 55 are formed in the opposite direction to any of the moving directions before and after the button holding mechanism 4''. Further, the position of the needle under the button is determined by the moving direction 15 of the button holding mechanism 4〇. By the movement mechanism 50, the button holding mechanism 40' of the holding _σβ is relatively moved with respect to the position of the needle under the needle, and the button is stitched. First, the position of the left and right needles of the button 8 shown in Fig. 7 and the shape of the groove of the right and left movement groove cam 51 shown in Fig. 8 will be described. 2〇Comparative brother 7(a), As you can see from the figure 7(b), the left and right movements of the needle position under the button are usually fixed. That is, the first, third, fifth, seventh, eighth, ninth, u, 13, 15, and 16 needles are usually at the seventh (a). ) Figure 7 and Figure 7(b) show the lower needle on the right side, and the 2nd, 4th, 6th, 10th, 12th, and 14th needles usually perform the lower needle on the left side. At this time, the left and right position of the lower needle position is based on the 8th (a). The left and right movement of the left and right movement mechanism shown in the figure is the shape of the groove of the groove cam 51 in 200912073. Next, the position of the inner side and the front side of the button B shown in Fig. 7 and the figure 8(b) and 8 (c) The correspondence between the shape of the groove of the groove cam before and after the movement is shown in the figure. 5 The movement of the lower needle position before and after the movement is similar to the U-shaped seam and the X-shaped seam. In the approximate U-stitch, the first to eighth stitches are used. On the back side of the 7th (a)th and 7th (b)th, the 9th to 16th stitches are performed on the front side. On the other hand, in the X-stitch, the i-th, 3, 5, 7, 8, 10, 12, 14 needles usually on the back side of the 7th (8) and 7th (b) Perform the '2nd, 4th, 6th, 9th, Uth, 13th, 15th, and 16th stitches on the front side. 10 At this time, the stitching mode of the button should be approximated by U-stitch or X-stitch. The feed adjustment lever 58b of the mechanism 58 is determined by the engagement of the feed wheel 58a with any of the arc-shaped guides 56a, 57a. That is, when the feed wheel is engaged with the arc-shaped guide 56a, it is formed according to the eighth ( b) Approximation 1 shown in the figure; movement of the groove shape of the groove groove 54 for the word slot, when the feed wheel 58a is combined with the paper guide member card 15, 'forms an X-shaped seam according to the figure 8(c) The groove shape of the groove cam 55 is used. Further, as shown in Figs. 8(b) and 8(4), since the arc-shaped guides 56a' to 57a which are swung by the groove cams %, 55 are opposite in direction, they are close. The shape groove groove cam 54 and the X-slot groove cam 55 are formed in the opposite direction to any of the movement directions before and after the button holding mechanism 40. 2〇 At this time, whether it is an approximate u-slot or an x-slot The third position, that is, the needle position at the beginning is the right rear side. The 16th needle, that is, the needle position at the end is the right front side. That is, the start position and end of the needle position below the staple The position is the same as the U-stitch and the x-stitch. Here, since the left-right movement of the button holding mechanism 40 is usually fixed, 22 200912073, there is no change between the approximate stencil and the X-slot. The start position and the end position of 1 are moved forward and backward in the same manner as the stencil and the stencil. The groove shape of the groove cam 54 and the groove shape of the groove cam 55 and the groove for the X-shaped groove are used. The groove shape of the cam 55 is the same as the movement direction at the time of completion of the sewing of the buckle holding mechanism 40 until the start of sewing, and as described above, in order to transmit the power of the speed reduction shaft 31, 10 15 is required to sew the button Β The number of stitches (16) is rotated during the period of the hand, and the front and rear moving groove cams and the right and left moving groove cams 51 form grooves for moving the total number of needles required for the combination. That is, after the button is stitched and the next button is closed, the groove cam is changed from the groove shape in which the 16th needle is moved to the groove shape in which the first needle is formed. < ’ Then, the needle number adjusting mechanism 30 cuts off the power transmission from the body motor after the 16th needle is lowered and the next needle is stitched to the next needle. Therefore, the start position and the end position of the needle position below the staples are similar to those of the X-stitch, and the approximate U-slot groove cam 54 and the sigmoid groove groove cam 55 have respective groove shapes. When the 16th needle is changed to the third needle, the direction of the shaking of each of the shaking members is the same. (Ringing direction of the arc-shaped guide member before and after the start of the stapling) Next, the relationship between the swinging direction of the round (four) materials 56a, 57a before and after the start of the stitching of the above-mentioned fasteners and the sewing method selection mechanism % will be described in detail. Fig. 9 is an explanatory view showing the relationship between the groove shape of the slightly U-shaped movement groove 54 and the X-shaped movement groove cam 55 before and after the start of sewing of the button B and the position of the rollers 1 and 5 of each of the swing members. The 1st figure shows the positional relationship between the respective rocking members and the feed wheel 58a before and after the start of the stitching = 23 200912073 Fig. 10(8) shows the positional relationship when the needle is finally cleared (16th stitch), the first position 〇 _ shows the relative positional relationship before (at the end of) the buckle, and the 10th (4) shows the relative positional relationship when the needle is below the (8) needle at the beginning of the buckle. 5 When the stud is completed and the deceleration 停止 is stopped at the ideal stop position, the cam groove of the U-slot groove cam 54 and the 1-slot groove cam 55 and the rocking members 56, 57 engaged with the cam grooves are approximated. The positional relationship between the rollers 56c and 57c is in the positional relationship shown in Fig. 9. At this time, the center of the roller 56e is located on the line of the 9th (b) which is the middle position in the middle of the switching of the button holding mechanism 40 from the last needle down to the first lower movement. At this time, the positional relationship of the rocking members 56, 57 is as shown in the first figure (9), the rocking member brothers, 57 round orphan guides 56a, 57a are located on the same circumference, and at the same time, the branch k is adjusted to eH dry 58b. The rotational axis of the wheel 58a is set along the arcuate guides 56a, 57a at this time. Therefore, the feed wheel 58a of the % selection mechanism is rotated by the feed adjustment member, and is easily transferred from one of the arc-shaped guides 56a, 57a to the other. In other words, when the number of suture stitches of one of the stapling buttons is completed, the rotation force transmitted to the deceleration shaft 3! is automatically cut by the stop mechanism 3, thereby approximating the u-slot groove cam 54 and the X-slot groove. The rotation of the cam 55 is stopped, and the position of the rocking member is opened to form the sewing machine selection mechanism 20 as shown in Fig. 1G(b). Also, in the last position of the needle under the button (16th pin), among the rollers 56c, 57c. Located on the line of Fig. 9(a), the rocking member % at this time has a positional relationship as shown in the first H). At the lower needle lowering position (first stitch) after the end of the above-mentioned fastening, the center of the rollers 56c, 57c is located on the line 24 200912073 of the figure 9 (4), and the positional relationship of the rocking members 56, 57 at this time As shown in Figure 10(c). That is, after the end of one of the staplings, the shaking directions of the rocking members 56, 57 which are performed before the start of the next stapling are the same in the direction substantially in the Y-axis direction. At this time, the front ends of the arcuate guide members 56a, 57a of the rocking members 56, 57 are usually positioned on the same line as the direction substantially 5 along the X-axis direction. Therefore, when the rocking members 56, 57 are located at the positions of the first (a) and the first (c), the feed wheels 58 & can also be easily transferred from one of the arc-shaped guides 56a, 57a. To the other. That is, even if the original center should be on the line of the figure 9 (b), the rollers 56c, 57c are decelerated for some reason, and the stop position is deviated, and the position of the front position is 9 (a) or 9 (1) At either or both of the positions on the line of the phantom, the front ends of the arcuate guides 56a, 57a of the rocking members 56, 57 are generally still on the same line substantially in the direction of the X-axis direction. When the stop positions of the u-slot groove cam 54 and the X-slot groove cam 55 are shifted, the button holding mechanism 4 can be easily switched between the front and rear 15 movements. (Description of the operation) The operation of the button fastening machine 1 configured as described above is performed. First, when the stitching of the button B as the suture is performed, the button holding mechanism 4 is attached to the upper surface of the mattress unit 21, The buckle is held between the pair of clamping claws 41, and the fabric c to be sewn is placed between the button structure 2 and the needle plate 12. At this time, the feeding adjustment lever 58b of the sewing mechanism and the adjusting mechanism 58 is determined to be near. _ word slit or χ L. For example, when performing an approximate U-stitch, operate the feed adjustment lever ' 煲The conveyance wheel 58a is engaged with the arcuate guide 56a. The movement of the left and right movement transmission member Μ 25 200912073 and the bottom plate 42 and the position adjustment of the sewing method selection mechanism 58 are performed according to the stroke of the button hole of the buckle B, < The buttonhole of the button B is most suitable for the left and right movement of the button holding mechanism 40 and the forward and backward movement stroke. Then, the driving of the body motor is started, and when the pedal is depressed, the adjustment arm 33 is disengaged from the recess 32a of the plate cam 32, thereby generating When the interlocking shaft 34 is rotated, the switching lever 28 and the brake lever 29 are rotated upward to transmit the rotational power to the main shaft, the line fishing shaft, and the deceleration shaft 31. Therefore, the button B performs a predetermined movement to carry the needle to the hook. 13 stitches are formed in sequence. 10 15 20 After that, the adjustment arm 33 is fitted to the recess 32a of the plate cam 32, and the switching lever 28 and the brake lever 29 are rotated to the lower side with the rotation of the interlocking shaft 34. The main shaft, the wire hook shaft, and the deceleration shaft 31 cut off the rotational power. Then, the inertially driven driven pulley 27 is rotated to the fitting portion, and the brake lever 29 is used to stop the rotation. ～叫呵+叫々疋初Η乍 is transmitted from the spindle to the figure. Not well known The movable knife of the tangential mechanism, until the inertial rotation of the pulley 27 is stopped, the end of the ring of the last needle of Jing is the end of the 财 1 财 1 she buckled the sewing operation. When the rough and handsome sewing operation, the yang will be sutured The buckled cloth c is removed from the buttoning machine (10), and two buttons and fabrics for sewing are placed. When the type of the buckle on the temple is changed, the stroke of the buttonhole is changed. The connection between the member 53 and the bottom plate 42 =::r holds the movement of the mechanism by about 4°, and: thereby: the buckle: the section _ retaining mechanism 4° before and after the movement stroke. Momentum. The cutting stroke is most suitable for the buckle holding mechanism Shifting 26 200912073 When the approximate U-slot and the stencil are switched, the sewing method selection mechanism 58 is operated to rotate the feed wheel 58a from one of the arc-shaped guides 56a or 57a to the other. -By. For example, when switching from the approximate U-stitch to the 缝-stitch, the feed adjusting lever 58b is operated to transfer the feed roller 58a from the arc-shaped guide 56a to the arc-shaped guide 57a. Then, by stepping on the activation pedal again, the button is stitched in the same procedure as described above. (Operation and Effect of the Button Machine of the Embodiment) According to the above embodiment, the first stitch and the last 101 stitch of the needle under the stitching of the button are not the same as the button hole of the U-shaped seam or the X-shaped stitch. Therefore, before the completion of the sewing of one button until the button of the button is stopped, the rocking ends of the arc-shaped guides 56a, 57a of the two rocking members 56, 57 are all moved in the same direction, and may be in the shape of arcs. The guides 56a, 57a are arranged in the same position in the shaking direction. Therefore, before and after the start of a button, the arc-shaped guides 56a, 57a 15 /α are aligned on the same circumference, that is, the most suitable slit selection mechanism 58 from one of the arc-shaped guides 56 & Or 57& is transferred to the other arc-shaped guide 57a or 56a, even if the stop positions of the arc-shaped guides 5, such as 57a are deviated, the front ends of the arc-shaped guides 56a, 57a are not conventionally known. The portions are deviated in different directions and deviate in the same direction, so that the deviation of the arcuate guides 563, 5 and 20 can be reduced, and the slit selection mechanism 58 can be more easily transmitted. Therefore, it is possible to provide a more efficient buttoning machine that can perform switching operations frequently and smoothly. When the slit selection mechanism 58 is transferred from one of the circular guides 56a or 57a to the other of the arcuate guides 563 or 57&, the feed roller 58a can be reduced to hit the other arcuate guide 56a or 57a. The method selection mechanism 58 and each of the arc-shaped guides 27 200912073 56a'57a|is a secret of the damage, and can provide a more reliable buttoning machine. (Others) 5 10 15 20 Further, the positions of the approximate U-shaped slit groove cam 54 and the stencil groove cam 55 may be replaced with each other. At this time, the groove shape of each of the groove cams 54, 55 is formed to be transmitted to the handsome holding mechanism 40 by the matching position of each of the groove cams 54, 55 and the rocking members 56, 57 which are swung by the respective groove cams %, 55: In the relationship of movement, the near-slot and the X-slot are correctly performed by the respective groove cams. In the above-described embodiment, i for the right and left movement groove cams are provided, and the movement groove cams are provided corresponding to the slightly U-shaped and x-slots, and the left and right movement groove cams and the slightly U-shaped movements are closed. Two sets are provided, and the aforementioned movement groove cam may be provided with a tamping. At this time, the arrangement of the front and rear moving groove cams and the left and right moving material cams is replaced, the rocking members %, 57 are engaged with the respective moving groove cams, and the respective rocking members 56, 57 are arc-shaped guides and 573 are engaged. The selection mechanism 58 converts the displacement of the direction into the displacement of the direction by micro-junction of the bottom of the bell crank and the gripper. Further, the front-rear movement groove cam is engaged with the rocking arm 52, and the proud wrist 52 is connected to the bottom plate 42 of the mechanism 40 to displace the father gentleman 2 indicator. The displacement of the axis direction is converted into the γ-axis direction. In addition, at this time, the state of the needle object (4) under each sewing method is not clocked or reversed, and the material of each (10) is in the order of money. The embodiment is not limited to the scope of the features of the invention, and the embodiment may be omitted. For example, the groove cam can be replaced with a plate cam. 28 200912073 [Circular Simple Description 3 FIG. 1 is a side view of the buckle machine of the embodiment of the present invention.
