發明概要
本發明的目的是進一步開發一種開頭所述類型的縫紉機,使得接縫圖案得到改進。SUMMARY OF THE INVENTION The object of the present invention is to further develop a sewing machine of the type mentioned at the beginning, so that the seam pattern is improved.
根據本發明,該目的通過一種用於縫紉機的操作方法來實現,該方法包括以下步驟:在織物片中縫製至少一個接縫,同時使用織物進給驅動機構在織物進給方向上同時進給該織物片,以及在縫製接縫時操作縫紉機的針進給單元,使得針在製造相應的針腳時以與織物進給方向相反地進給織物片。According to the invention, this object is achieved by an operating method for a sewing machine, which method comprises the steps of sewing at least one seam in a fabric sheet while simultaneously feeding the fabric feed direction in the fabric feed direction using a fabric feed drive mechanism Fabric pieces, and the needle feed unit of a sewing machine operated when a seam is sewn, so that the needles feed the fabric pieces in the opposite direction to the fabric feed direction when the corresponding stitches are manufactured.
令人驚訝地發現,根據織物質量和織物厚度並且根據縫紉線參數,如果用於進給織物片的針進給單元在與附加的織物進給驅動機構的織物進給方向相反的方向上操作,則接縫圖案得到改進。雖然預料的是針進給單元和織物進給驅動機構的這種”反向操作”將導致接縫圖案不良,但實際上通過根據織物類型和縫紉線類型的這種反向操作能夠可再現地改進接縫圖案。Surprisingly, it has been found that, depending on the fabric quality and fabric thickness, and according to the sewing thread parameters, if the needle feed unit for feeding a fabric piece is operated in a direction opposite to the fabric feed direction of the additional fabric feed drive mechanism, The seam pattern is improved. Although it is expected that this "reverse operation" of the needle feed unit and the fabric feed driving mechanism will cause a poor seam pattern, in fact, this reverse operation according to the type of fabric and the type of sewing thread can be reproduced reproducibly Improved seam patterns.
織物進給驅動機構的與針進給單元有關的可調整相位關係允許在織物進給驅動機構的週期性操作順序與針進給單元之間微調反向操作,這可以用於優化接縫圖案。織物進給驅動機構和針進給單元的相應操作順序的一個週期可以與縫紉機的精確地形成一個針腳的週期一致。The adjustable phase relationship of the fabric feed drive with respect to the needle feed unit allows fine adjustment of the reverse operation between the periodic operation sequence of the fabric feed drive and the needle feed unit, which can be used to optimize the seam pattern. One cycle of the corresponding operation sequence of the fabric feed driving mechanism and the needle feed unit may coincide with the cycle of the sewing machine to form exactly one stitch.
操作順序微調的優點特別適用於在縫製接縫時執行的相位關係調整。例如,織物進給驅動機構的週期性操作順序與針進給單元之間的第一相位關係可以存在於待縫製的接縫的開始處,而該類型的不同相位關係可以存在於接縫的末端處。這種相位關係調整允許縫紉機適應接縫形成期間不同的縫紉條件。The advantages of fine-tuning the operating sequence are particularly applicable to the phase relationship adjustment performed when sewing a seam. For example, the first phase relationship between the periodic operation sequence of the fabric feed driving mechanism and the needle feed unit may exist at the beginning of the seam to be sewn, and this type of different phase relationship may exist at the end of the seam Office. This phase relationship adjustment allows the sewing machine to adapt to different sewing conditions during seam formation.
步長關係被證明特別適合於改進接縫圖案,所述步長關係使得在進行針腳的同時借助於針進給單元進給織物片的針進給步長就絕對值而言小於在製造針腳的同時借助於織物進給驅動器進給織物片的進給步長。針進給步長與織物進給步長的絕對關係可以在1/10至2/1的範圍內。在反向操作中,絕對針進給步長通常也可以大於織物進給步長。The step length relationship has proven to be particularly suitable for improving the seam pattern, which makes the stitch feeding step of feeding the fabric piece by means of the needle feeding unit while the stitches are performed, smaller in absolute value than the stitches used in manufacturing the stitch At the same time, the feed step of the fabric sheet is fed by means of a fabric feed driver. The absolute relationship between the needle feed step and the fabric feed step can be in the range of 1/10 to 2/1. In reverse operation, the absolute needle feed step can also be larger than the fabric feed step.
配置成執行根據本發明的方法的縫紉機的優點對應於上面參考操作方法所描述的那些優點。縫紉機可以是單針縫紉機,也可以是雙針縫紉機。The advantages of a sewing machine configured to perform the method according to the invention correspond to those described above with reference to the method of operation. The sewing machine can be a single-needle sewing machine or a double-needle sewing machine.
配置為織物夾具的織物進給驅動器允許織物進給單元中的織物進給相對於針進給單元的致動的獨立致動。替代性地,織物進給驅動機構也可以被配置為包括至少一個頂部進給裝置的頂部進給單元和/或包括至少一個底部進給裝置的底部進給單元。織物進給驅動機構能夠在接縫形成期間通過與織物片的摩擦接觸來進給待縫製的織物片。A fabric feed driver configured as a fabric clamp allows independent actuation of the fabric feed in the fabric feed unit relative to the actuation of the needle feed unit. Alternatively, the fabric feeding driving mechanism may also be configured to include a top feeding unit including at least one top feeding device and / or a bottom feeding unit including at least one bottom feeding device. The fabric feed driving mechanism is capable of feeding the fabric sheet to be sewn by frictional contact with the fabric sheet during the formation of the seam.
針進給單元的步進電機允許精確設置針進給步長,所述步進電機作用於調整軸上以調整針進給步長,所述步長可以微小的增量變化,特別是幾乎連續變化。The stepper motor of the needle feed unit allows precise setting of the needle feed step size, which acts on the adjustment shaft to adjust the needle feed step size, which can be changed in small incremental increments, especially almost continuously Variety.
配置成限定織物進給驅動機構與針進給單元之間的相位關係的控制單元允許在織物進給驅動機構與針進給單元之間靈活地設置反向操作。A control unit configured to define a phase relationship between the fabric feed driving mechanism and the needle feeding unit allows flexible setting of a reverse operation between the fabric feeding driving mechanism and the needle feeding unit.
較佳實施例之詳細說明
圖1示出了縫紉單元1的主要部件的局部示意圖,所述縫紉單元1特別用於例如生產帶有袋口的袋子,所述袋口被滾邊修整。縫紉單元1可以用於將諸如滾邊的附加的織物部分縫製到諸如褲子部分或西裝外套部分的基本織物部分上。縫紉單元也可以用於縫製有蓋口袋或貼邊口袋。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows a partial schematic view of the main components of a sewing unit 1 which is particularly used, for example, to produce bags with pocket openings, which are trimmed by piping. The sewing unit 1 can be used to sew an additional fabric portion such as a piping to a basic fabric portion such as a pants portion or a blazer portion. The sewing unit can also be used to sew covered pockets or welt pockets.
當將接縫縫製到織物片中時,織物片同時以被驅動方式在織物進給方向2(下文也稱為縫紉方向)上進給。縫紉方向2沿著圖1中包括的笛卡爾xyz坐標系的x方向延伸。When the seam is sewn into the fabric sheet, the fabric sheet is simultaneously fed in the fabric feed direction 2 (hereinafter also referred to as the sewing direction) in a driven manner. The sewing direction 2 extends along the x direction of the Cartesian xyz coordinate system included in FIG. 1.
縫紉單元1具有適應於縫製織物片的縫紉機3,縫紉機3被配置為包括縫紉針4、5(例如,見圖2)的雙針縫紉機。當在縫紉方向2上看時,滾邊或蓋部折疊且進給裝置佈置在縫紉針4、5的上游,換句話說,在負x方向上偏移。從現有技術中已知所述滾邊進給裝置的一般工作模式。關於此的更多信息可以在先前公佈的文獻DE 100 16 410 C1、DE 199 26 866 C1和DE 198 45 624 C1以及那裡引用的參考文獻中找到。The sewing unit 1 has a sewing machine 3 adapted to sew a fabric piece, and the sewing machine 3 is configured as a two-needle sewing machine including sewing needles 4, 5 (see, for example, FIG. 2). When viewed in the sewing direction 2, the piping or cover is folded and the feeding device is arranged upstream of the sewing needles 4, 5, in other words, offset in the negative x direction. The general operating mode of the hemming feed device is known from the prior art. More information on this can be found in the previously published documents DE 100 16 410 C1, DE 199 26 866 C1 and DE 198 45 624 C1 and the references cited there.
織物片位於縫紉機1的支承板7上。支承板7限定了平行於xy平面的支承平面。The fabric piece is located on a support plate 7 of the sewing machine 1. The support plate 7 defines a support plane parallel to the xy plane.
在根據圖1的示意圖中僅由虛線畫出並且從文獻EP 3 088 589 A總體已知的織物進給驅動機構的從動織物夾具8用於將織物片壓靠在待生產的接縫的相應側上的支承板7上並沿著縫紉方向2進給織物片。縫紉機3允許可選地啟動、例如暫時啟動織物片的附加的針進給單元。The driven fabric gripper 8 of the fabric feed drive mechanism, which is only drawn by dashed lines and is generally known from document EP 3 088 589 A in the schematic diagram according to FIG. 1, is used to press the fabric sheet against the corresponding seam to be produced. The fabric sheet is fed on a support plate 7 on the side and in the sewing direction 2. The sewing machine 3 allows an additional needle feed unit to be optionally activated, for example temporarily activated.
縫紉單元1的可以被配置為觸摸屏的可操作顯示器被提供給用戶以選擇縫紉程序、輸入縫紉數據和監控縫紉過程。未示出的顯示器經由圖1中的示意圖所示的中央控制單元9致動。An operable display of the sewing unit 1 that can be configured as a touch screen is provided to the user to select a sewing program, enter sewing data, and monitor the sewing process. An unshown display is actuated via a central control unit 9 shown in the schematic diagram in FIG. 1.
包括夾具框架的織物夾具8由覆蓋罩10覆蓋。The fabric jig 8 including the jig frame is covered with a cover cover 10.
縫紉單元1具有主框架11,所述主框架11承載縫紉機3以及配置成將織物片進給到針腳形成區域的織物進給傳送部件和配置成從針腳形成區域排出織物片的織物排出部件。主框架11包括支承板7。縫紉單元1的滑動板12安裝在支承板7的區域中。在進給期間,織物片沿著滑動板12滑動。The sewing unit 1 has a main frame 11 which carries a sewing machine 3 and a fabric feed conveying member configured to feed a fabric sheet to a stitch formation region and a fabric discharge member configured to eject the fabric sheet from the stitch formation region. The main frame 11 includes a support plate 7. The sliding plate 12 of the sewing unit 1 is mounted in the region of the support plate 7. During the feeding, the fabric sheet slides along the sliding plate 12.
圖2至7示出了用於產生針進給運動的針進給單元18的細節,針進給單元18被配置成使得進入織物片的縫紉針4、5沿縫紉方向2或與縫紉方向2相反地進給織物片或者使得進入織物片的縫紉針4、5沒有織物進給功能。圖2和3示出了針進給單元18處於設置位置”在縫紉方向2上的針進給”,換句話說,在正x方向上。圖4和5示出的設置位置是針進給單元18被配置成執行與縫紉方向2相反地針進給運動,換句話說,在負x方向上。圖6和7示出的針進給單元18的設置位置中,縫紉針4、5沒有織物進給功能。2 to 7 show details of a needle feeding unit 18 for generating a needle feeding movement, the needle feeding unit 18 being configured such that the sewing needles 4, 5 entering the fabric piece are in the sewing direction 2 or the sewing direction 2 Conversely, the fabric piece is fed or the sewing needles 4, 5 entering the fabric piece have no fabric feed function. 2 and 3 show the needle feeding unit 18 in the setting position "needle feeding in the sewing direction 2", in other words, in the positive x direction. The setting positions shown in FIGS. 4 and 5 are such that the needle feeding unit 18 is configured to perform a needle feeding motion opposite to the sewing direction 2, in other words, in the negative x direction. In the setting position of the needle feeding unit 18 shown in Figs. 6 and 7, the sewing needles 4, 5 have no fabric feeding function.
針進給驅動器源於臂軸19,所述臂軸19在縫紉機3的臂20(見圖2)中延伸。在自由端處,臂軸19非旋轉地連接到可手動操作的手輪21。The needle feed driver originates from an arm shaft 19 which extends in the arm 20 (see FIG. 2) of the sewing machine 3. At the free end, the arm shaft 19 is non-rotatably connected to a manually operable hand wheel 21.
經由偏心輪22,臂軸19作用於針進給調整齒輪機構23上。調整齒輪機構23被配置為舌形齒輪機構。The arm shaft 19 acts on the needle feed adjustment gear mechanism 23 via the eccentric 22. The adjustment gear mechanism 23 is configured as a tongue gear mechanism.
在縫紉操作中,臂軸19是由驅動電機驅動的,所述驅動電機在圖中未示出,並且可以容納在例如縫紉機3的支承板7之下的支架24或主框架11中。In the sewing operation, the arm shaft 19 is driven by a drive motor, which is not shown in the figure, and can be accommodated in, for example, the bracket 24 or the main frame 11 below the support plate 7 of the sewing machine 3.
調整齒輪機構23產生針進給單元18的輸出桿25的擺動運動。輸出桿25的擺動角度和擺動幅度均由調整齒輪機構23的相應齒輪設置預先確定。通過旋轉配置為齒輪軸26的調整軸來執行齒輪設置,所述齒輪軸26與調整齒輪機構23相互作用並且也平行於臂軸19延伸。相應地,齒輪軸26的相應角度設置引起針進給單元在縫紉方向2上的不同進給行程。The adjustment gear mechanism 23 generates a swinging motion of the output lever 25 of the needle feeding unit 18. Both the swing angle and swing width of the output lever 25 are determined in advance by the corresponding gear settings of the adjustment gear mechanism 23. The gear setting is performed by rotating an adjustment shaft configured as a gear shaft 26 that interacts with the adjustment gear mechanism 23 and also extends parallel to the arm shaft 19. Accordingly, the corresponding angular setting of the gear shaft 26 causes different feed strokes of the needle feed unit in the sewing direction 2.
齒輪軸26的角度設置可以借助於針進給切換裝置27來改變,所述針進給切換裝置27被配置為步進電機形式的致動器。所述步進電機經由框架鎖閂28以未更詳細示出的方式剛性連接到縫紉機3的框架上。步進電機27的電機軸29經由槓桿驅動機構30連接到齒輪軸26。調整齒輪機構23的框架、槓桿驅動機構30的輸出槓桿部件31和齒輪軸26彼此不可旋轉地連接。電機軸29的從圖6和7中的中立位置開始的擺動運動是+/-30°,以達到根據圖2和3的最大”向前針進給”和根據4和5的最大”向後針進給”的兩個位置。The angle setting of the gear shaft 26 can be changed by means of a needle feed switching device 27 which is configured as an actuator in the form of a stepper motor. The stepper motor is rigidly connected to the frame of the sewing machine 3 via a frame latch 28 in a manner not shown in more detail. The motor shaft 29 of the stepping motor 27 is connected to the gear shaft 26 via a lever driving mechanism 30. The frame of the adjustment gear mechanism 23, the output lever member 31 of the lever driving mechanism 30, and the gear shaft 26 are non-rotatably connected to each other. The swing motion of the motor shaft 29 from the neutral position in FIGS. 6 and 7 is +/- 30 ° to reach the maximum “forward needle feed” according to FIGS. 2 and 3 and the maximum “back needle” according to 4 and 5 Feed "positions.
步進電機27與縫紉單元1的中央控制單元9進行信號通信。該控制單元9用於經由織物夾具8、針進給切換裝置27的步進電機和用於臂軸19的驅動電機來致動例如織物進給驅動機構。The stepping motor 27 performs signal communication with the central control unit 9 of the sewing unit 1. The control unit 9 is used to actuate, for example, a fabric feed driving mechanism via a fabric clamp 8, a stepper motor of the needle feed switching device 27, and a drive motor for the arm shaft 19.
如圖2至7所示,針進給單元18可以借助於針進給切換裝置27在”縫紉方向2的針進給”(見圖2/3)、”與縫紉方向2相反地針進給”(見圖4/5)與”無針進給功能的中立位置”(見圖6/7)三個位置之間切換。As shown in FIGS. 2 to 7, the needle feeding unit 18 can be “needle fed in the sewing direction 2” (see FIG. 2/3) and “needle fed in the opposite direction to the sewing direction 2” by means of the needle feeding switching device 27. "(See Fig. 4/5) and" Neutral position without needle feed function "(see Fig. 6/7).
輸出桿25將由調整齒輪機構23限定的擺動幅度傳遞到針桿連桿軸36。因此,針桿連桿軸36的擺動幅度由輸出桿25的擺動幅度限定。針桿連桿軸36也平行於臂軸19延伸。The output lever 25 transmits the swing amplitude defined by the adjustment gear mechanism 23 to the needle lever link shaft 36. Therefore, the swing amplitude of the needle bar link shaft 36 is defined by the swing amplitude of the output lever 25. The needle bar link shaft 36 also extends parallel to the arm shaft 19.
針桿連桿軸36非旋轉地連接到用於針桿38的針桿連桿37,兩個縫紉針4、5借助於針夾持器39固定到所述針桿38上。The needle bar link shaft 36 is non-rotatably connected to a needle bar link 37 for a needle bar 38 to which the two sewing needles 4, 5 are fixed by means of a needle holder 39.
針4、5響應針桿連桿軸36的擺動幅度圍繞針進給擺動軸40執行擺動運動。The needles 4 and 5 perform a swing motion around the needle feed swing shaft 40 in response to the swing amplitude of the needle bar link shaft 36.
圖2至7進一步示出了用於在向上和向下方向上致動針桿38的臂軸曲柄42,以及包括帶有支承點的螺紋桿調整元件44的螺紋桿43。2 to 7 further show an arm shaft crank 42 for actuating the needle bar 38 in upward and downward directions, and a threaded rod 43 including a threaded rod adjustment element 44 with a support point.
當操作縫紉機3時,縫製相應的接縫,同時,同時在縫紉方向2上、即在織物進給方向上以借助於織物進給驅動機構、即借助於織物夾具8驅動的方式進給織物片。當縫製相應的接縫時,操作針進給單元18,使得針4、5在製作相應的針腳時與織物進給方向2相反地進給織物片。因此,在縫紉操作期間,針進給單元18的操作位置或者如圖4和5所示、或者是經由步進電機27的相應步進位置限定的中間位置,所述中間位置位於如圖4和5所示的”最大向後針進給”位置與如圖6和7所示的中立位置之間。When the sewing machine 3 is operated, the corresponding seams are sewn, and at the same time, the fabric pieces are fed in the sewing direction 2, that is, in the fabric feed direction, by means of a fabric feed drive mechanism, that is, driven by the fabric clamp 8 . When sewing the corresponding seam, the needle feed unit 18 is operated so that the needles 4 and 5 feed the fabric piece in the opposite direction to the fabric feed direction 2 when making the corresponding stitches. Therefore, during the sewing operation, the operation position of the needle feed unit 18 is either as shown in FIGS. 4 and 5 or an intermediate position defined by the corresponding step position of the stepper motor 27, which is located as shown in FIGS. Between the "Maximum Backward Needle Feed" position shown in 5 and the neutral position shown in Figures 6 and 7.
步進電機27允許在如圖2/3所示的”最大向前/向後針進給”位置與如圖6/7所示的中立位置之間進行幾乎連續的調整。The stepper motor 27 allows almost continuous adjustment between the "maximum forward / backward needle feed" position shown in Fig. 2/3 and the neutral position shown in Fig. 6/7.
如果織物進給驅動機構、即織物夾具8在製作針腳時具有週期性操作順序,則所述織物進給驅動機構8在製作相應的針腳時以與針進給單元18有關的可調整相位關係工作。通過相應地經由控制單元9致動織物夾具8的進給驅動機構,可以在形成相應的接縫期間甚至在製造相應的針腳時調整所述相位關係。If the fabric feed driving mechanism, that is, the fabric clamp 8 has a periodic operation sequence when making stitches, the fabric feed driving mechanism 8 works with an adjustable phase relationship related to the needle feed unit 18 when making the corresponding stitches . By actuating the feed drive mechanism of the fabric clamp 8 via the control unit 9 accordingly, the phase relationship can be adjusted during the formation of the corresponding seams or even when the corresponding stitches are manufactured.
在製造針腳時借助於針進給單元18沿著可經由步進電機27調整的針進給步長進給織物片,所述針進給步長可以就絕對值而言小於在製作針腳時借助於織物夾具8進給織物片的進給步長。一般而言,針進給步長也有可能就絕對值而言大於進給步長。針進給步長/進給步長的絕對步長比可以在1/10至2/1的範圍內、特別是在1/10至8/10的範圍內、在2/10至7/10的範圍內、以及例如在3/10的範圍內、在4/10的範圍內、在5/10的範圍內、或甚至在6/10的範圍內。織物進給步長可以在2.5mm的範圍內。反向操作中的絕對針進給步長可以在0.1mm至3.5mm之間的範圍內。The fabric piece is fed by means of a needle feed unit 18 during the manufacture of the stitches along a needle feed step that can be adjusted via a stepper motor 27, which can be smaller in absolute value than by means of The feeding step of the fabric clamp 8 for feeding the fabric pieces. In general, the needle feed step may also be larger than the feed step in absolute value. The absolute step ratio of the needle feed step / feed step can be in the range of 1/10 to 2/1, especially in the range of 1/10 to 8/10, in the range of 2/10 to 7/10 Within the range of, for example, within the range of 3/10, within the range of 4/10, within the range of 5/10, or even within the range of 6/10. The fabric feed step can be in the range of 2.5mm. The absolute needle feed step in reverse operation can be in the range of 0.1mm to 3.5mm.
作為配置為織物夾具的織物進給驅動機構的替代,織物進給驅動機構也可以被配置為頂部進給單元和/或底部進給單元。從DE 196 03 294 C1已知一種配置成提供織物頂部進給運動的進給爪。從EP 2 330 241 B1已知一種配置成提供織物底部進給運動的進給齒。Instead of the fabric feed driving mechanism configured as a fabric clamp, the fabric feed driving mechanism may also be configured as a top feeding unit and / or a bottom feeding unit. From DE 196 03 294 C1, a feed jaw configured to provide a feed movement of the top of the fabric is known. From EP 2 330 241 B1, a feed tooth configured to provide a feed motion of the bottom of the fabric is known.
調整針進給步長可以以受控的方式進行,例如響應於檢測織物厚度。為此,控制單元9能夠與織物厚度傳感器(未示出)通信並且在達到預定的織物厚度時致動步進電機27。還可以響應於所測量的織物進給速度來進行調整針進給。為此,在縫紉操作期間,例如使用光學感測器監控織物進給的速度。Adjusting the needle feed step size can be performed in a controlled manner, for example in response to detecting the fabric thickness. To this end, the control unit 9 can communicate with a fabric thickness sensor (not shown) and actuate the stepper motor 27 when a predetermined fabric thickness is reached. The needle feed can also be adjusted in response to the measured fabric feed speed. For this reason, during the sewing operation, the speed of the fabric feed is monitored, for example, using an optical sensor.
