Field of the Invention The present invention relates to a control device and method for controlling the feeding size of a belt when sewing a belt to a fabric. [Previous 3 Background of the Invention Fig. 7 is a block diagram showing the configuration in which the tape feeding size control 1 is set to 1 in the prior art.帛8® is a front view showing the operation panel 10 15 2 of the size control device. Fig. 9 is a perspective view showing a part of the sewing material. The feed size control device is provided with an operation panel 2, a sewing machine rotation sensor 3, a control circuit 4, and a feed motor drive circuit 5. The delivery size control device (, when the belt (4) 8__ material 7 is used by the seam cutter body, (4) the feeding size of the belt 8 of the machine body. When the stretchable belt 8 is sewn to the cloth 7, the tension is applied to the belt while the portion to be sewn, and the portion to which the object is sewn by applying tension. In the former part, the seam material 7 is shrunk to produce a fold net; in the latter part, the cloth after sewing is: not = but is flat. At this time, the tension and the number of needles for each process are divided into a number of work + no collection for each part. Then, using the operator 3, the "control and feed motor 6 with the value of Yunlonglong, that is, the rotary machine 2 rotation sensing rotation angle, and the electric motor from the control circuit 4 to the feed motor ==_ is used. The stitches set by the number of stitches = the tension set in the month are set in each work, and the tape 8 is fed. The blistering operation period 20 1253485 is similar to the feeding size control device 1, and has such a control device, that is, instead of the tension of each step, the feeding size of the feeding belt 8 is input, the number of the needles is fed, and the feeding is performed. The tension of each step is obtained by the size, and the tension is obtained by the tension obtained during the sewing operation for the number of needles to be input. (5) The above-mentioned prior art is controlled by the number of needles, and the sewing operation is performed by the number of needles in each step δ (see, for example, Japanese Patent Laid-Open No. Hei 7-68067 and Japanese Patent Publication No. Hei 7-44984) . In the sewing device, since the rotational speed of the drive shaft of the sewing machine body generates an inertial force on the cloth feed mechanism, the sewing pitch Ρ7 is different, that is, the positional interval at which the needle passes on the cloth differs. For example, when the square turn speed is 3〇〇〇miirl, the seam spacing Ρ7 is 2.0mm; when the rotation speed is 5000mirrl, the initial pitch P7 is 2,2mm; when the rotation speed is (9)00111111·1, the sewing pitch P7 is 2.4mm. Therefore, in the control of the number of needles as described above, even if the same number of needles is used, the length of the process varies depending on the rotation speed of the drive shaft.

，操作板28包含有輸入機構40、作爲顯示機構的顯示部41 。輸入機構40是輸入要求尺寸的機構，該要求尺寸是要缝 在布料23上預定區域的帶狀物24的尺寸。包含著由輸入機 構所輸入的要求尺寸的資訊，被送到控制回路30，控制回 路3〇控制顯示部41，使顯示部41顯示包含著由輸入機構4〇 15所輸入的要求尺寸的資訊。 根據不同的縫製製品22，在把帶狀物24縫製到布料23 上時，特別是在縫製具有彈性伸縮性的帶狀物24時，有時 存在著對帶狀物24施加張力、以伸長狀態縫製在布料23上 的部分、和不對帶狀物24施加張力、以自然狀態縫製在布 2〇料23上的部分。前者部分是爲了在縫製後的布料23上形成 折敵，使布料23呈收縮狀；後者部分是爲了在縫製後的布 料23上不形成折皺，使布料23呈平展狀。這時，縫製裝置 中根據元成後的狀悲、換㊂之根據在缝製時對帶狀物 24施加張力，把布料23上的缝製帶狀物以的全部區域，劃 1253485 分爲若干個區域部分，每個區域部分有 進行縫製。例如，在第3__认丄4 的工序，化樣 料㈣*〜 女式短裤的褲腳口部設置 表緊一，劃分爲第1〜第3這樣三個工序。 ，可操作板28具有若干個操作賴，操作者操作各鍵42時 以輸U序數、各工序中的設定張力、各工序間長度 〜正设定值等的輸入資訊。工序數，是指把布料23上的 縫製帶狀物24的全部區域劃分爲若干個 區域部分，對每個 10 區域部分進行縫製時的工序的數，該數也是區域部分的數 ’在第3圖的例中，工序數是3。各工序被分配有工序序號 ’按照縫製動作的順序，依次分配爲卜2、…、η的自然數 。廷裏的‘η’’ ’是最後的工序序號，是與工序數同樣的數 字0 各工序中的設定張力，是在各工序中，在對應的區域 部分上進行縫製時，對帶狀物24施加的張力，是工序序號 15爲“1”的第1工序中的第i設定張力、王序序號爲“2”的第2工 序中的第2設定張力、…、工序序號爲“n，，的第n工序中的第n 設疋張力。因此’第3圖的例中，輸入第1〜第3設定張力。 各工序間長度(下面有時稱爲“進給長度”），是縫在各工 序所對應區域部分上的帶狀物24的長度方向尺寸，是第1工 20序中的第1進給長度、第2工序中的第2進給長度.....第η 工序中的第η進給長度。因此，在第3圖的例中，輸入第1〜 第3進給長度。各進給長度是不施加張力的自然狀態的尺寸 ’無論對應區域部分是平展部分還是收縮部分，都與完成 後的縫製製品中的尺寸相同。該進給長度，相當於要求尺 15 1253485 寸，是在各工序的縫製動作期間，應送入縫紉機本體25的 帶狀物24的尺寸。 修正設定值，是用於修正進給棍26的送入尺寸的修疋 值。從理論上說，送入親26的各報（片）38、39每旋轉〆周’ 可送入與各輥38、39的全周長相等尺寸的帶狀物24，但是 ，由於帶狀物24的伸縮性和材質等原因，各輥38、39旋轉 一周時送入的帶狀物24的尺寸，有時與各輥38、39的全周 長不相同。用來修正這一點的值，就是上述的修正設定值 ’該修正值對每個帶著物24設定。這裏所述的周長，是指 10外周面的周方向尺寸；所說的全周長，是指沿著輥38、39 周方向全周的外周面的周方向尺寸。 由輸入機構40輸入的輸入資訊，被送到控制回路3〇。 顯示機構41被控制回路3〇控制，可顯示該輸入資訊，所以 ，在輸入上迹的輸入資訊時，可以一邊確認顯示的輸入資 15訊，-邊進行輸入操作，具有便利性。 控制回路30包含有作爲計算處理機構的中央計算處理 單兀(CPU)、作爲存儲機構的唯讀記憶體⑽m)和隨機存取 吕己ί思體（RAM)等的印,〖咅辨

與=給馬達27的動作量對應，因此，也是與進給輕26的動 乍里十應的值。本實施形_中，通過計測該驅動脈衝數， 檢測進給馬達26動作量。 另外，控制回路30具有計算機構的功能。即，在記憶 體内贱存儲著所需動作量計算程式，CPU讀出並執^ 需動作量計算程式，計算所需動作量，該所需動作量，是 爲了把與輸人的要求尺寸對應的帶狀物24送人而所需的^ 給輥26的動作量。具體地說，根據輪人的^〜第:給長

式（1)中的P，是當一個驅動脈衝給與驅動電路31時， 與進給報26的旋轉數(旋轉角度)相當的進給報26的周長。如 前所述，進給輥26具有外徑不同的一對輥38、39，該一對 5 輥38、39連動地旋轉，所以，與1脈衝對應的周長是相同的 。上述的周長可是與任一個親相關的值，在本實施中，是 與輥38相關的周長。 另外，式（1)中的C，是進給修正值。該進給修正值C ，用來修正各輥38、39的全周長、與各輥38、39旋轉一周 10 時實際送入的帶狀物24的尺寸（下面有時稱爲“實際進給尺 寸”)的差，是各輥38、39的全周長與實際進給尺寸的比。 下面，以輥38爲例具體說明。設一個輥（片）38的全周長 爲X，輥38的實際進給尺寸爲Y，則進給修正值C用式(2) 表示。 15 C = Y/X …(2) 這裏，由輸入機構40輸入的修正設定值，可以是進給 修正值C，也可以是實際進給尺寸Y。輥38的全周長X是 機械的尺寸，是一定值，所以，預先存儲在控制回路30的 記憶體内，通過計測並輸入由帶狀物24引起變化的實際進 20 給尺寸Y，也可以由控制回路30計算進給修正值C。無論 哪種情況，進給修正值C可根據輸入的修正設定值得到。 另外，控制回路30具有判斷機構的功能。即，在記憶 體内預先存儲著判斷程式，CPU讀出並執行判斷程式，將

In addition to the above, the sewing device 21 can also be used to sew other 12 1253485 stitching products 22 on which the belt 24 is sewn on the cloth 23, for example, the elastic band sewing elastic band can be sewn to the tights and the waist of the tights. The waist of the work, the waist of the romper and the jumpsuit, the twisted elastic band are sewn, loose: the waist that is sewn. Clothing and sweatpants 5 10 15 a The sewing device 21' includes a slit machine body rib, a feed 26, an entrance 27, an operation panel 28, a control circuit 30, and a feed motor drive circuit. The operation panel 28, the control circuit 3A, and the feed motor drive circuit 31 constitute a delivery size (4) device 2A. The shaft main body 25 as a sewing mechanism is a mechanism for sewing the belt 24 on the cloth 23. The machine body 25, with the needle plate 35 and the pressure plate %, puts the cloth 23 placed on the slightly horizontal support surface of the cloth support table 34 (the third figure and the first note 'in the please and the towel wheel'), and the side The cloth (not shown) feeds it in a predetermined sewing direction, and the needle is reciprocated in the up and down driving direction, so that sewing can be performed. Further, in the sewing device 21, the belt 24 is sent to the sewing machine body 25, and the belt μ can be sewn to the cloth. The feed roller 26 as the feeding mechanism is a mechanism for feeding the ribbon 24 into the slit machine body 25, specifically, a mechanism for feeding the ribbon 24 to the ribbon supply port of the pressure plate 36, which Has a pair of views, %. In each of the views 38, 39, the roller 38 is larger than the outer diameter of the other roller 39, and the two rollers rotate about the mutually parallel axes and elastically rotate in conjunction with each other. These mouths are fortunate than the 38 to rotate the ribbon 24 so that the ribbon 24 can be fed into the sewing machine body 25. The feed motor 27 as the feed drive mechanism is a mechanism for driving the feed parent 26 to rotate 13 1253485, and it may be, for example, a stepping motor. The feed motor 27 rotates one of the rollers 38 and 39. In the present embodiment, the roller 38 is rotated, and the other roller 39 is also driven to rotate. A belt feeding device including a feed roller 26 and a feed motor 27 is mounted on the sewing machine body 25. Above the sewing machine body 25, for example, a belt supply device (not shown) called an automatic feeding device supported on a support (not shown) is provided. The tape feeding device feeds the tape 24 supplied from the tape feeding device to the sewing machine body 25. Fig. 5 is a front view showing the operation panel 28. As shown in FIGS. 1 to 4, the operation panel 28 includes an input unit 40 and a display unit 41 as a display unit. The input mechanism 40 is a mechanism for inputting a required size which is the size of the strip 24 to be sewn to a predetermined area on the cloth 23. The information including the required size input by the input mechanism is sent to the control circuit 30, and the control circuit 3 controls the display unit 41 to cause the display unit 41 to display information including the required size input by the input unit 4〇15. According to the different sewn products 22, when the belt 24 is sewn onto the cloth 23, particularly when the elastically stretchable belt 24 is sewn, tension is applied to the belt 24 to be stretched. A portion that is sewn on the cloth 23 and a portion that does not apply tension to the belt 24 and is sewn to the cloth 2 in a natural state. The former part is for forming an entrapment on the cloth 23 after sewing, and the cloth 23 is contracted; the latter part is for not forming wrinkles on the cloth 23 after sewing, so that the cloth 23 is flat. At this time, in the sewing device, according to the shape after the element is formed, the tension is applied to the belt 24 at the time of sewing, and the entire area of the sewing belt on the cloth 23 is divided into several parts by 1253485. In the area section, each section is sewn. For example, in the process of the 3rd__4, the sample (4)*~ The bottom of the pants of the women's shorts is set to the first step, and the first to third steps are divided into three steps. The operable panel 28 has a plurality of operations, and the operator inputs the input information such as the U-number, the set tension in each step, and the length between the steps and the positive set value when the operator operates the keys 42. The number of steps refers to the number of steps in which the entire area of the sewing tape 24 on the cloth 23 is divided into a plurality of area portions, and the number of the portions of each of the 10 area portions is sewed, and the number is also the number of the area portion. In the example of the figure, the number of processes is three. Each step is assigned a process number ‘ in the order of the sewing operation, and the natural numbers of Bu 2, ..., η are sequentially assigned. 'η'' of the Tingri is the last process number, and is the same number as the number of processes. The set tension in each process is the tape 24 when sewing is performed in the corresponding zone portion in each process. The applied tension is the i-th set tension in the first step in which the step number 15 is "1", the second set tension in the second step in which the king number is "2", ..., and the step number is "n," In the example of the third figure, the first to third set tensions are input. The length between each step (hereinafter sometimes referred to as "feed length") is The dimension in the longitudinal direction of the strip 24 in the portion corresponding to each step is the first feed length in the first work order and the second feed length in the second step. The nth feed length. Therefore, in the example of Fig. 3, the first to third feed lengths are input. Each feed length is a size of a natural state in which no tension is applied, regardless of whether the corresponding portion is flat or contracted. The part is the same size as the finished sewing product. The feed length is equivalent to the requirement. 15 1253485 inches is the size of the strip 24 to be fed into the sewing machine body 25 during the sewing operation of each step. The corrected set value is a correction value for correcting the feed size of the feed stick 26. It is said that the newspapers (sheets 38, 39 fed to the pro 26 can be fed into the belt 24 of the same size as the entire circumference of each of the rollers 38, 39 per revolution, but due to the belt 24 The size of the strip 24 fed when the rolls 38 and 39 are rotated one rotation may be different from the entire circumference of each of the rolls 38 and 39 due to the stretchability and the material. The value for correcting this is The correction set value 'this correction value is set for each carrier 24. The circumference described here refers to the circumferential dimension of the outer peripheral surface of 10; the full circumference refers to the circumference of the roller 38, 39 The circumferential direction dimension of the outer circumferential surface of the entire circumference. The input information input by the input mechanism 40 is sent to the control circuit 3. The display mechanism 41 is controlled by the control circuit 3〇, and the input information can be displayed, so the input is traced. When inputting information, you can confirm the input of the input message 15 Operation is convenient. The control circuit 30 includes a central processing unit (CPU) as a calculation processing unit, a read-only memory (10) m as a storage unit, and a random access memory (RAM). , 咅 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Once the 隹 隹 检 检 核 核 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' Count is used as the amount of operation of the acknowledgment 16 1253485 up to 26. In the present embodiment, the feed motor 27 is a stepping motor, and is supplied from the control circuit Bayer motor drive circuit (hereinafter sometimes referred to as "drive circuit,") 31. __ 'This commands the feed motor 27 ^ to rotate the feed motor 27 according to the number of rotations of the drive motor 27 from the _call_command motor 27, in other words, the feed motor 27 is operated. That is, the output shaft is rotated. Hereinafter, the rotation of the shaft is referred to as the rotation of the feed motor 27. 10 15 20 Thus, the number of drive pulses given to the drive circuit 31 from the control circuit 30 corresponds to the amount of operation of the motor 27, and therefore, it is also a value corresponding to the movement of the feed light 26. In the present embodiment, the amount of operation of the feed motor 26 is detected by measuring the number of drive pulses. Additionally, control loop 30 has the function of a computing mechanism. That is, the required action amount calculation program is stored in the memory, and the CPU reads and executes the required action amount calculation program to calculate the required amount of action, which is to correspond to the required size of the input. The amount of action of the feed roller 26 is required for the belt 24 to be delivered. Specifically, the number of set pulses is obtained as the required motion amount according to the number of the person's ^~:: giving length' in each guard. The set pulse number Pulse and the number of pulses required to rotate the feed motor 27 for feeding the strips 24 of the second to nth feed lengths = this, the calculation is performed in consideration of the input correction set value. . More specifically, during the sewing operation of each step, the size of the belt bundle to be reversed into the slit machine body 25 is set to red, and the number of set pulses is calculated by the following formula (1). Setg 17 1253485 P ulse = (L/P)xC."(l) P in equation (1) is the number of rotations (rotation angle) with the feed 26 when a drive pulse is applied to the drive circuit 31. The length of the feed is 26. As described above, the feed roller 26 has a pair of rollers 38, 39 having different outer diameters, and the pair of five rollers 38, 39 rotate in conjunction with each other, so that the circumference corresponding to one pulse is the same. The above-described perimeter may be a value associated with either one, and in this embodiment, is the circumference associated with the roller 38. Further, C in the formula (1) is a feed correction value. The feed correction value C is used to correct the full circumference of each of the rolls 38, 39 and the size of the strip 24 actually fed when the rolls 38, 39 are rotated one time (hereinafter sometimes referred to as "actual feed" The difference in size ") is the ratio of the total circumference of each of the rolls 38, 39 to the actual feed size. Hereinafter, the roller 38 will be specifically described as an example. When the total circumference of one roller (sheet) 38 is X and the actual feed size of the roller 38 is Y, the feed correction value C is expressed by the formula (2). 15 C = Y/X (2) Here, the correction set value input by the input means 40 may be the feed correction value C or the actual feed size Y. The full circumference X of the roller 38 is a mechanical size and is a constant value. Therefore, it is stored in the memory of the control circuit 30 in advance, and the actual feed 20 size Y caused by the change of the belt 24 can be measured and input. The feed correction value C is calculated by the control circuit 30. In either case, the feed correction value C can be obtained from the input correction set value. In addition, the control circuit 30 has the function of a judging mechanism. In other words, the determination program is stored in advance in the memory, and the CPU reads and executes the determination program, and the detected operation amount (hereinafter sometimes referred to as "detection operation amount") and the required operation amount 18 a 〇 3485

In step s7, it is determined that the feed motor 27 is in the forward direction, Feed 2 The direction rotation of the 0 f-shaped object 24 is also rotated in the reverse direction, that is, in the direction in which the belt 24 is pulled back. Specifically, it is judged that the pulse given to the feed motor drive circuit 31 is rotated in the forward direction. It is also a drive pulse that rotates in the opposite direction. This judgment is made because the feed motor 27 adjusts the tension of the belt 24, and sometimes the strip 24 is pulled back slightly. 21 1253485 When feeding When the motor 27 rotates in the normal rotation direction, the process proceeds to step s8, and "pulse is added to the count pulse count P count for each pulse, and the process proceeds to step s10. If the feed motor 27 is rotated in the reverse direction, the process proceeds to step S9, for each pulse, subtract "1" from the measured pulse number P count, and proceed to step s10.
5 在步驟slO，判斷計測脈衝數P count與設定脈衝數P ulse是否相同。如果不相同，則判斷爲現在的工序未結束， 返回步驟s6。如果相同，則判斷爲現在的工序已結束，進 入步驟sll。 在步驟sll，判斷是否存在下一工序。具體地說，是判 10 斷現在的工序序號與輸入的工序數是否相同。如果不相同 ，則判斷爲有下一工序，進入步驟S12，在現在的工序序號 上加上“1”，返回步驟s2。如果相同，則判斷爲沒有下一工 序，進入步驟s 13，結束控制動作。 根據上述送入尺寸控制裝置20和控制方法，由進給馬 15 達27驅動進給輥26，將帶狀物24送入缝紉機本體25時，根 據輸入到各工序的帶狀物24的進給長度，控制回路30計算 驅動脈衝數即設定的脈衝數P u 1 s e，該驅動脈衝數與爲了送 入該進給長度的帶狀物24而所需的進給馬達27的旋轉數( 旋轉角度)相當。另外，控制回路30給與驅動電路31的驅動 20 脈衝數被計測，由控制回路30判斷該計測脈衝數Pcount與 設定脈衝數Pulse是否相同，控制回30控制進給馬達27，使 進給馬達27的旋轉數與設定脈衝數Pulse相當。 這樣，通過輸入要缝製在布料23上的帶狀物24的進給 長度，使進給馬達27只旋轉能夠將該長度的帶狀物24送入 22 1253485 的旋轉數，使進給輥26旋轉，可將帶狀物24送入。因此， 例如即使因驅動軸的旋轉速度等缝紉機本體25的動作條件 、或者有無疊合部等的布料23的狀態等引起縫製間距的差 異’也能防止帶狀物24的縫製尺寸受到上述差異的影響， 5可以用高的尺寸精度缝製帶狀物24。而且，實現該高尺寸 精度時，操作者只要輸入進給長度即可，不必考慮缝紉機 本體25的動作條件和布料23的狀態地進行輸入操作，可以 使輸入操作極爲容易。 縫製在布料23上時的帶狀物24的張力，是在進給輥26 10到縫紉機本體25之間被施加的，由於在進給輥26的上流側 不施加張力，所以，即使每個工序的設定張力不同，相對 於進給輥26—周旋轉的送入尺寸也保持一定，張力不影響 送入尺寸，可容易地控制送入尺寸。第6圖的步驟s9中，進 、、’e秦b26疋反轉，這只是爲了調節張力，對送入尺寸的影響 15 在誤差範圍内，控制很容易。 上述實施形態僅表示本發明的一個例子，在本發明的 範圍内，可以變更其構成。例如，前述的實施形態中，控 制回路3〇是作爲送入檢測機構，但是，也可以如幻圖所示 ，另外地設置馬達旋轉感測器29,將它作爲送人檢測機構 20。該馬達旋轉感測器29，檢測進給馬達27的動作量即進給 馬達27的旋轉數(旋轉角度）。檢測出的進給輕26的旋轉數， 送到控制回路3〇。具體地說，馬達旋轉感測器29,例如是 設在進給馬達27上的旋轉編碼器，每旋轉預定的角度時， 產生脈衝，將該脈衝送到控制回路3〇。在控制回路3〇，計 23 1253485 測該脈衝’取得計測脈衝數。該計測脈衝數也是與進給輥 26的動作量對應的值，可以代替計測驅動脈衝的計測脈衝 數，可進行同樣的控制。 另外’前述實施形態中，要求尺寸是輸入每工序的進 5 給長度的尺寸，但是，也可以不採用要求尺寸，而是輸入 各工序的完成後尺寸。完成後的尺寸，是將各工序對應的 布料23的區域部分縫製完成後的尺寸，是縫製後不施加外 力的自然狀態時的尺寸。該完成後尺寸，也是與在一個工 序的縫製動作期間應送入縫紉機本體25的帶狀物24的尺寸 10 對應的值，考慮到布料23的材質和厚度等因素，可以從完 成後尺寸，求出在一個工序的缝製動作期間應送入縫紉機 本體25的帶狀物24尺寸。因此，可進行與前述實施例同樣 的控制。 前述實施形態中，是例舉了有若干工序的例子，但也 15 適用於只有一個工序的情形，可達到優異的效果。另外， 在前述實施形態中，是採用進給輥作爲送入機構，採用進 給馬達作爲送入驅動機構，但是並不限於此，也可以採用 其他的構造。另外，送入尺寸的檢測，也可不採用檢測送 入馬達的旋轉數，而是採用光學感測器，直接檢測帶狀物 20 的送入量。另外，關於布料和帶狀物，也可以是前述例以 外的物料。 在不脫離本發明精神和主要特徵的範圍，可以有其他 各種實施形態。因此，前述實施形態僅僅是例舉而已，本 發明的範圍在權利要求中表示，不受說明書限制。另外， 24 1253485 在權利要求範圍内的各種變形或變更，均在本發明範圍内。 L圖式簡單說明3 第1圖是表示本發明一實施形態的送入尺寸控制裝置 的框圖。 5 第2圖是表示備有送入尺寸控制裝置的縫製裝置局部 的立體圖。 第3圖是表示用缝製裝置缝製的一例産品的立體圖。 第4圖是將縫製産品的局部放大表示的立體圖。 第5圖是表示操作板的正面圖。 10 第6圖是表示送入尺寸控制裝置執行的送入尺寸控制 方法的流程圖。 第7圖是表示已往技術中的帶狀物送入尺寸控制裝置 的構成的框圖。 第8圖是表示送入尺寸控制裝置的操作板的正面圖。 15 第9圖是表示縫製物局部的立體圖。 【圖式之主要元件代表符號表】 1…控制裝置 24…帶狀物 7…布料 25…縫紉機本體 8…帶狀物 26···進給幸昆 9···疊合部 27···進給馬達 20…控制裝置 28…操作板 21…缝製裝置 29···馬達旋轉感測器 22…缝製產品 30···控制回路 23…布料 31···驅動電路 25 1253485 34…支承台 35…針板 36…壓板 38,39…輥 40…輸入機構 41···顯示部 42…操作鍵 45…旋轉感測器 46…張力感測器 265 At step s10, it is judged whether or not the number of measurement pulses P count is the same as the number of set pulses P ulse. If they are not the same, it is determined that the current process is not completed, and the process returns to step s6. If they are the same, it is determined that the current process has ended, and the process proceeds to step s11. At step s11, it is judged whether or not there is a next process. Specifically, it is determined whether the current process number is the same as the number of input processes. If it is not the same, it is determined that there is a next step, and the process proceeds to step S12, and "1" is added to the current process number, and the process returns to step s2. If they are the same, it is judged that there is no next process, and the process proceeds to step s 13, and the control operation is ended. According to the above-described feed size control device 20 and the control method, when the feed roller 15 drives the feed roller 26 and feeds the ribbon 24 into the sewing machine body 25, the feed is fed according to the tape 24 input to each process. The length, the control circuit 30 calculates the number of driving pulses, that is, the set number of pulses P u 1 se, the number of driving pulses and the number of rotations of the feed motor 27 required for feeding the strip 24 of the feeding length (rotation angle) )quite. Further, the number of pulses of the drive circuit 30 given to the drive circuit 31 is measured, and the control circuit 30 determines whether the number of measured pulses Pcount is the same as the set pulse number Pulse, and controls 30 to control the feed motor 27 to cause the feed motor 27 The number of rotations is equivalent to the set pulse number Pulse. Thus, by inputting the feed length of the belt 24 to be sewn on the cloth 23, the feed motor 27 is rotated only to rotate the length of the belt 24 into the number of rotations of 22 1253485, so that the feed roller 26 Rotating, the ribbon 24 can be fed. Therefore, for example, even if the difference in the sewing pitch is caused by the operating conditions of the sewing machine main body 25 such as the rotational speed of the drive shaft, or the presence or absence of the state of the cloth 23 such as the overlapping portion, the sewing size of the belt 24 can be prevented from being different. Influence 5, the ribbon 24 can be sewn with high dimensional accuracy. Further, when the high dimensional accuracy is achieved, the operator can input the feed length, and the input operation can be performed without considering the operating conditions of the sewing machine body 25 and the state of the cloth 23, making the input operation extremely easy. The tension of the belt 24 when sewing on the cloth 23 is applied between the feed roller 26 10 and the sewing machine body 25, since no tension is applied to the upstream side of the feed roller 26, even if each process The set tension is different from that of the feed roller 26, and the feed size is kept constant. The tension does not affect the feed size, and the feed size can be easily controlled. In step s9 of Fig. 6, the in and the 'e Qin b26疋 are reversed, which is only for adjusting the tension and affecting the feeding size. 15 Within the error range, the control is easy. The above embodiment is merely an example of the present invention, and the configuration can be changed within the scope of the present invention. For example, in the above-described embodiment, the control circuit 3A is used as the feed detecting means. However, as shown in the phantom, the motor rotation sensor 29 may be separately provided as the delivery detecting means 20. The motor rotation sensor 29 detects the amount of operation of the feed motor 27, that is, the number of rotations (rotation angle) of the feed motor 27. The detected number of rotations of the feed light 26 is sent to the control circuit 3〇. Specifically, the motor rotation sensor 29 is, for example, a rotary encoder provided on the feed motor 27, and pulses are generated every time a predetermined angle is rotated, and the pulse is sent to the control circuit 3A. In the control loop 3, the pulse 23' is measured to obtain the number of measurement pulses. The number of measurement pulses is also a value corresponding to the amount of operation of the feed roller 26, and the same control can be performed instead of the number of measurement pulses of the measurement drive pulse. Further, in the above-described embodiment, the required size is the size of the input length of each step. However, the required size may be input instead of the required size. The size after completion is a size obtained by sewing the region of the cloth 23 corresponding to each step, and is a size in a natural state in which no external force is applied after sewing. The size after completion is also a value corresponding to the size 10 of the belt 24 to be fed into the sewing machine body 25 during the sewing operation in one step, and considering the material and thickness of the cloth 23, etc., the size can be obtained from the finished size. The size of the belt 24 to be fed into the sewing machine body 25 during the sewing operation in one step. Therefore, the same control as in the foregoing embodiment can be performed. In the above embodiment, an example in which there are a plurality of steps is exemplified, but the case is also applied to a case where there is only one step, and an excellent effect can be obtained. Further, in the above embodiment, the feed roller is used as the feed mechanism, and the feed motor is used as the feed drive mechanism. However, the present invention is not limited thereto, and other configurations may be employed. Further, the detection of the feed size may be performed by directly detecting the feed amount of the belt 20 by using an optical sensor instead of detecting the number of rotations of the feed motor. Further, as for the cloth and the belt, it may be a material other than the foregoing examples. Other various embodiments are possible without departing from the spirit and scope of the invention. Therefore, the foregoing embodiments are merely illustrative, and the scope of the invention is defined by the claims. Further, various changes or modifications within the scope of the claims are intended to be within the scope of the invention.
