本專利申請要求德國專利申請DE 10 2014 223 720.3的優先權，並且通過引用該申請而包括其內容。 The priority of the German patent application DE 10 2014 223 720.3 is hereby incorporated by reference.
本發明涉及一種用於縫紉機的驅動組件，該驅動組件用於致動用於反轉縫紉方向的裝置和腳抬升裝置。此外，本發明涉及一種包括縫紉方向反轉裝置、腳抬升裝置和這種驅動組件的縫紉機。 The present invention relates to a drive assembly for a sewing machine for actuating a device for reversing a sewing direction and a foot lifting device. Further, the present invention relates to a sewing machine including a sewing direction reversing device, a foot lifting device, and such a driving assembly.
由現有技術中顯而易見的在先使用得知的縫紉機中的上述類型的驅動組件包括一方面用於反轉縫紉方向和另一方面用於抬升腳的分立的(單獨的)驅動器。 A drive assembly of the above type, which is known from the prior art as known in the prior art, comprises a separate (separate) drive for reversing the sewing direction on the one hand and for lifting the foot on the other hand.
DE 10 2008 016 353 A1記載了一種縫紉機，該縫紉機具有用於抬升縫紉腳的抬升裝置和用於設定縫紉腳的輸送抬升量的抬升高度調節裝置，其中抬升裝置和抬升高度調節裝置具有共同的驅動器。 DE 10 2008 016 353 A1 describes a sewing machine having a lifting device for lifting a sewing foot and a lifting height adjusting device for setting a lifting amount of the sewing foot, wherein the lifting device and the lifting height adjusting device have a common drive .
本發明的一個目的在於提供一種用於縫紉機的複雜性降低的驅動組件和一種配備有這種驅動組件的縫紉機。 SUMMARY OF THE INVENTION An object of the present invention is to provide a drive assembly for a reduced complexity of a sewing machine and a sewing machine equipped with such a drive assembly.
根據本發明，通過這樣一種用於縫紉機的驅動組件實現所述目的， - 該驅動組件包括用於致動用於反轉縫紉方向的裝置並且用於實現腳抬升裝置的主驅動器，- 其中，在致動用於反轉縫紉方向的裝置時，主驅動器的驅動構件機械地聯接到用於反轉縫紉方向的裝置，並且- 其中，在致動腳抬升裝置時，主驅動器的同一驅動構件機械地聯接到腳抬升裝置。 According to the invention, the object is achieved by such a drive assembly for a sewing machine, - the drive assembly comprises a main drive for actuating the means for reversing the sewing direction and for implementing the foot lifting device - wherein the drive member of the main drive is mechanically coupled when actuating the means for reversing the sewing direction To the means for reversing the sewing direction, and - wherein, when the foot lifting device is actuated, the same drive member of the main drive is mechanically coupled to the foot lifting device.
根據本發明，通過將主驅動器與用於反轉縫紉方向的裝置和腳抬升裝置聯接成使得同一驅動構件可用於致動兩個裝置，可對兩個裝置使用僅一個主驅動器。這降低了驅動組件的成本。主驅動器的形式可以是提升磁體。縫紉方向的反轉可用於形成條縫(bar seam)，即用於互鎖。 According to the invention, by coupling the main drive with the means for reversing the sewing direction and the foot lifting device such that the same drive member can be used to actuate the two devices, only one main drive can be used for both devices. This reduces the cost of the drive assembly. The main drive can be in the form of a lifting magnet. The reversal of the sewing direction can be used to form a bar seam, ie for interlocking.
用於切換機械聯接的輔助驅動器--其中，在第一聯接位置，驅動構件機械地聯接到用於反轉縫紉方向的裝置，而在第二聯接位置，驅動構件機械地聯接到腳抬升裝置--使得能簡單地切換主驅動器一方面與用於反轉縫紉方向的裝置及另一方面與腳抬升裝置的機械聯接。輔助驅動器不驅動用於反轉縫紉方向的裝置或腳抬升裝置，而是僅用於切換聯接。因此，輔助驅動器的驅動力可比致動用於反轉縫紉方向的裝置或腳抬升裝置所需的驅動力低許多 倍。輔助驅動器由此可被設計成比第二主驅動器便宜得多且佔用更小的空間。輔助驅動器可被設計為比主驅動器弱的提升磁體。 An auxiliary drive for switching mechanical coupling - wherein, in the first coupled position, the drive member is mechanically coupled to the means for reversing the sewing direction, and in the second coupled position, the drive member is mechanically coupled to the foot lift - - enabling a simple switching of the main drive on the one hand with the device for reversing the sewing direction and on the other hand with the foot lifting device. The auxiliary drive does not drive the device for reversing the sewing direction or the foot lifting device, but only for switching the coupling. Therefore, the driving force of the auxiliary driver can be much lower than the driving force required to actuate the device for reversing the sewing direction or the foot lifting device. Times. The auxiliary drive can thus be designed to be much less expensive and take up less space than the second main drive. The auxiliary drive can be designed as a lifting magnet that is weaker than the main drive.
根據驅動組件的一個實施例，其中在不致動輔助驅動器的情況下實現第一聯接位置，為了反轉縫紉方向，僅需致動主驅動器，即不涉及輔助驅動器。這使得可以迅速反轉縫紉方向。 According to an embodiment of the drive assembly, wherein the first coupling position is achieved without actuating the auxiliary drive, in order to reverse the sewing direction, only the main drive has to be actuated, ie no auxiliary drive is involved. This makes it possible to reverse the sewing direction quickly.
可移位的驅動裝置--其中輔助驅動器對該可移位的驅動裝置起作用，該可移位的驅動裝置在第一移位位置將驅動構件聯接到用於反轉縫紉方向的裝置且在第二移位位置將驅動器聯接到腳抬升裝置--代表簡單和不昂貴的聯接元件。原則上，該驅動裝置也可連接成使得不由單獨的輔助驅動器移位。原則上，用於該驅動裝置的移位驅動器也可由主驅動器得到或者可使用可手動移位的驅動裝置。可移位的驅動裝置的第一移位位置可設置在輔助驅動器的第一驅動位置。可移位的驅動裝置的第二移位位置可設置在輔助驅動器的第二驅動位置。 a displaceable drive device - wherein an auxiliary drive acts on the displaceable drive device, the displaceable drive device coupling the drive member to the device for reversing the sewing direction in the first displaced position and The second displacement position couples the driver to the foot lift device - representing a simple and inexpensive coupling element. In principle, the drive can also be connected such that it is not displaced by a separate auxiliary drive. In principle, the shifting drive for the drive can also be obtained from the main drive or a manually displaceable drive can be used. The first displacement position of the displaceable drive device can be set at a first drive position of the auxiliary drive. The second displacement position of the displaceable drive can be set at the second drive position of the auxiliary drive.
驅動裝置的這樣的構型--其中在兩個聯接位置形成聯接之後，該驅動裝置與輔助驅動器分離--減少了驅動組件的各構件的磨損。輔助驅動器在用於反轉縫紉方向的裝置的驅動中未被涉及且在抬升裝置的驅動中也未被涉及，而是僅在聯接位置之間的切換中被涉及。驅動裝置可被設計成使得它被固定在兩個聯接位置。可通過例如借助預張緊彈簧和/或借助摩擦連接和/或通過形狀配合的預加 力將驅動裝置固定在聯接位置。 Such a configuration of the drive device, in which the drive device is separated from the auxiliary drive after the coupling is formed at the two coupling positions, reduces wear of the components of the drive assembly. The auxiliary drive is not involved in the drive of the device for reversing the sewing direction and is also not involved in the drive of the lifting device, but only in the switching between the coupling positions. The drive device can be designed such that it is fixed in two coupling positions. The pre-addition can be achieved, for example, by means of a pretensioning spring and/or by means of a frictional connection and/or by a form fit The force fixes the drive in the coupled position.
包括以下各者的縫紉機的優點對應於上文已參照驅動組件說明的優點：- 用於在縫紉材料中形成線縫的線跡形成工具，- 用於使縫紉材料沿縫紉方向移位的縫紉材料驅動器，- 用於反轉縫紉方向的裝置，- 腳抬升裝置，和- 根據本發明的驅動組件。 The advantages of the sewing machine including the following correspond to the advantages described above with reference to the drive assembly: - a stitch forming tool for forming a seam in the sewing material, - a sewing material for shifting the sewing material in the sewing direction Actuator, - means for reversing the direction of sewing, - foot lifting means, and - drive assembly according to the invention.
縫紉機的其中腳抬升裝置也可獨立於驅動組件被致動的實施例擴展了使用腳抬升裝置的選擇。可通過手動致動的桿或肘節桿進行獨立的致動。 The foot lift device of the sewing machine can also extend the choice of using the foot lift device independently of the embodiment in which the drive assembly is actuated. Independent actuation can be achieved by manually actuated levers or toggle levers.
腳抬升裝置的可移位的反轉桿在第一聯接位置可相對於驅動構件移動能實現腳抬升裝置獨立於驅動組件的致動。 The displaceable reversing lever of the foot lift device is movable relative to the drive member in the first coupled position to enable actuation of the foot lift device independently of the drive assembly.
反轉桿在驅動構件的相對移位期間在驅動構件的導向部中被引導使得反轉桿相對於驅動組件能實現在操作上可靠的定位。 The reversing lever is guided in the guide of the drive member during the relative displacement of the drive member such that the reversing lever can achieve an operatively reliable positioning relative to the drive assembly.

The direction VIII looks at the view.
縫紉機1具有立柱2、臂3和頭部4，從而與基板5一起縫紉機1的總體結構呈C形。未更詳細地示出的由主驅動器驅動的臂軸向上和向下驅動未示出的針桿，該針桿具有固定在其上的縫紉針。該針穿過針板中的針孔，所述針板構成代表縫紉機1的基板5的上側面的支承板7的一部分。 The sewing machine 1 has a column 2, an arm 3, and a head 4 so that the overall structure of the sewing machine 1 together with the substrate 5 is C-shaped. The arm driven by the main drive, not shown in more detail, drives the needle bar, not shown, axially up and down, the needle bar having a sewing needle fixed thereto. The needle passes through a pinhole in the needle plate, which constitutes a part of the support plate 7 representing the upper side of the substrate 5 of the sewing machine 1.
縫紉針與未示出的夾線器(旋梭)一起代表一對線跡形成工具，可借助所述線跡形成工具在縫紉材料中形成線縫。 The sewing needle together with a wire gripper (hob) not shown represents a pair of stitch forming tools by which a seam can be formed in the sewing material.
縫紉機1具有用於在縫紉期間壓持縫紉材料的未更詳細地示出的縫紉腳，也稱為壓腳。縫紉腳安裝在壓腳桿8上。 The sewing machine 1 has a sewing foot, also referred to as a presser foot, which is not shown in more detail for holding the sewing material during sewing. The sewing feet are mounted on the presser foot 8.
縫紉材料在縫紉過程中沿與圖1所示的笛卡爾xyz坐標系的x方向平行的縫紉方向被輸送。xy平面平行於支承板7延伸。z軸向上延伸。y軸平行於臂3延伸。 The sewing material is conveyed in a sewing direction parallel to the x direction of the Cartesian xyz coordinate system shown in Fig. 1 during sewing. The xy plane extends parallel to the support plate 7. z extends axially. The y-axis extends parallel to the arm 3.
為了沿正或負x方向輸送縫紉材料，使用未示出的下輸送腳。所述下輸送腳由下輸送軸9驅動。借助接合齒輪10和下軸11指定下輸送軸9的振盪運動的方向並由此指定在縫紉方向x上或與所述縫紉方向相反(-x)的輸送方向。 In order to convey the sewing material in the positive or negative x direction, a lower conveying leg, not shown, is used. The lower conveying foot is driven by the lower conveying shaft 9. The direction of the oscillating movement of the lower conveying shaft 9 is specified by means of the engaging gear 10 and the lower shaft 11 and thereby the conveying direction in the sewing direction x or opposite to the sewing direction (-x) is specified.
驅動組件14用於致動用於反轉縫紉方向的裝置12(該裝置也包括接合齒輪10和下軸11)並且用於致動用於抬升壓腳桿8上的壓腳的腳抬升裝置13。 The drive assembly 14 is for actuating the device 12 for reversing the sewing direction (the device also includes the engagement gear 10 and the lower shaft 11) and for actuating the foot lift device 13 for lifting the presser foot on the booster foot 8.
驅動組件14的主驅動器15在立柱2向臂3的過渡處被收納在縫紉機1中並且經由機械聯接一方面用於致動用於反轉縫紉方向的裝置12且另一方面用於操作腳抬升裝置13。主驅動器15被設計為提升磁體。如果用於反轉縫紉方向的裝置12被主驅動器15致動，則主驅動器15的被設計為套筒活塞16的驅動構件機械地聯接到用於反轉縫紉方向的裝置12。在致動腳抬升裝置13時，主驅動器15的同一驅動構件16機械地聯接到腳抬升裝置13。 The main drive 15 of the drive assembly 14 is housed in the sewing machine 1 at the transition of the upright 2 to the arm 3 and is used on the one hand to actuate the device 12 for reversing the sewing direction and on the other hand for operating the foot lift device 13. The main drive 15 is designed to lift the magnet. If the device 12 for reversing the sewing direction is actuated by the main drive 15, the drive member of the main drive 15 designed as a sleeve piston 16 is mechanically coupled to the device 12 for reversing the sewing direction. When the foot lift device 13 is actuated, the same drive member 16 of the main drive 15 is mechanically coupled to the foot lift device 13.
所述機械聯接由被收納在縫紉機1的臂3中的輔助驅動器17切換。輔助驅動器17被設計為比主驅動器15弱的提升磁體。在輔助驅動器17的第一聯接位置，套筒活塞16機械地聯接到用於反轉縫紉方向的裝置12，而在輔助驅動器17的第二聯接位置，主驅動器15的驅動構件16機械地聯接到腳抬升裝置13。 The mechanical coupling is switched by the auxiliary drive 17 housed in the arm 3 of the sewing machine 1. The auxiliary driver 17 is designed as a lifting magnet that is weaker than the main driver 15. In the first coupling position of the auxiliary drive 17, the sleeve piston 16 is mechanically coupled to the means 12 for reversing the sewing direction, and in the second coupling position of the auxiliary drive 17, the drive member 16 of the main drive 15 is mechanically coupled to The foot lifting device 13.
主驅動器15和輔助驅動器17被固定在縫紉機1的機架上。 The main drive 15 and the auxiliary drive 17 are fixed to the frame of the sewing machine 1.
圖3和4示出處於休止位置的驅動組件14的主要構件。 在根據圖3和4的休止位置，輔助驅動器17不起作用。 Figures 3 and 4 show the main components of the drive assembly 14 in the rest position. In the rest position according to Figures 3 and 4, the auxiliary drive 17 does not function.
滑叉18以機械地固定的方式連接到套筒活塞16。滑叉18也是用於將主驅動器15一方面機械聯接到用於反轉縫紉方向的裝置12且另一方面機械聯接到腳抬升裝置13的驅動構件的一部分。旋轉滑動器20的桿端19突出在滑叉18的叉腳之間。旋轉滑動器可繞平行於y方向的樞轉軸線20a(參見圖2)樞轉並且連接到拉桿21。旋轉滑動器20和拉桿21是用於反轉縫紉方向的裝置12的構件。借助拉桿21，下軸11可繞其縱向軸線樞轉且由此可經由接合齒輪10限定下輸送裝置的輸送方向(+x/-x)。 The shift fork 18 is coupled to the sleeve piston 16 in a mechanically fixed manner. The slip fork 18 is also part of a drive member for mechanically coupling the main drive 15 to the device 12 for reversing the sewing direction on the one hand and to the foot lifting device 13 on the other hand. The rod end 19 of the rotary slider 20 protrudes between the fork legs of the sliding fork 18. The rotary slider is pivotable about a pivot axis 20a (see FIG. 2) parallel to the y-direction and is connected to the tie rod 21. The rotary slider 20 and the pull rod 21 are members of the device 12 for reversing the sewing direction. By means of the tie rod 21, the lower shaft 11 is pivotable about its longitudinal axis and thus the conveying direction (+x/-x) of the lower conveying device can be defined via the engagement gear 10.
處於休止位置的滑動銷23的驅動器部段22封閉滑叉18的叉開口。 The driver section 22 of the slide pin 23 in the rest position closes the fork opening of the slide fork 18.
處於休止位置的輔助驅動器17的往復活塞24與滑動銷23間隔開且不對後者起作用。 The reciprocating piston 24 of the auxiliary drive 17 in the rest position is spaced apart from the slide pin 23 and does not act on the latter.
在背離輔助驅動器17的一側，滑叉18具有以燕尾導向部形式設計的縱向導向部25。腳抬升裝置13的推桿26的自由端在縱向導向部25中被引導。推桿26機械地連接到腳抬升軸27以使其樞轉。腳抬升軸27又作用在壓腳桿8上。 On the side facing away from the auxiliary drive 17, the sliding fork 18 has a longitudinal guide 25 designed in the form of a dovetail guide. The free end of the push rod 26 of the foot lifting device 13 is guided in the longitudinal guide 25. The push rod 26 is mechanically coupled to the foot lift shaft 27 for pivoting. The foot lift shaft 27 acts on the presser foot bar 8 again.
圖5和6示出處於鎖定位置的驅動組件14的主要構件，在鎖定位置縫紉輸送方向從+x反轉為-x。在鎖定位置，輔助驅動器17保持休止，即不起作用。在鎖定位置，主驅動器15被驅動且套筒活塞16與滑叉18一起被收回。在這種情況下，滑動銷23的驅動器部段22與旋轉滑動器20的桿端19協作配合並且使後者與根據圖4的休止位置相比沿圖6中的 順時針樞轉。以這種方式且借助樞轉後的拉桿以及借助鉸接在其上的下軸11和接合齒輪10，下輸送軸9移位且由此使輸送方向從+x反轉為-x。現在可例如在線縫的起點或線縫端部處縫合條縫。 Figures 5 and 6 show the main components of the drive assembly 14 in the locked position in which the sewing transport direction is reversed from +x to -x. In the locked position, the auxiliary drive 17 remains idle, i.e., does not function. In the locked position, the main drive 15 is driven and the sleeve piston 16 is withdrawn with the slip fork 18. In this case, the driver section 22 of the sliding pin 23 cooperates with the rod end 19 of the rotary slider 20 and the latter is compared to the rest position according to FIG. 4 along the rest position in FIG. Pivot clockwise. In this way and by means of the pivoted pull rod and by means of the lower shaft 11 and the engagement gear 10 hinged thereto, the lower conveying shaft 9 is displaced and thereby the conveying direction is reversed from +x to -x. The seam can now be sewn, for example, at the beginning of the seam or at the end of the seam.
在使滑叉18從休止位置移位到鎖定位置時，腳抬升裝置13的各構件的位置不變，因為滑叉18經由導向部25相對於推桿26移位。 When the slide fork 18 is displaced from the rest position to the lock position, the position of each member of the foot lift device 13 does not change because the slide fork 18 is displaced relative to the push rod 26 via the guide portion 25.
第一聯接位置在不致動輔助驅動器17的情況下到達，在該第一聯接位置，主驅動器15的驅動構件16、18聯接到用於反轉縫紉方向的裝置12。縫紉方向的反轉僅通過致動主驅動器15實現並且可非常快地執行。 The first coupling position is reached without actuating the auxiliary drive 17, in which the drive members 16, 18 of the main drive 15 are coupled to the means 12 for reversing the sewing direction. The reversal of the sewing direction is achieved only by actuating the main drive 15 and can be performed very quickly.
圖7和8示出處於腳抬升位置的驅動組件14的主要構件。所述腳抬升位置是如此實現的，首先，輔助驅動器17被暫時驅動，其中往復活塞24使滑動銷23從根據圖3和4的休止位置移動到根據圖7和8的腳抬升位置。在腳抬升位置，滑動銷23的自由驅動器端28移動到形成在推桿26的自由端處的互補底座中，從而形成滑叉18與推桿26的驅動聯接。現在，主驅動器15被驅動，使得套筒活塞16與滑叉18一起從休止位置被拉到被致動位置。這樣，在腳抬升位置，推桿26的自由端被滑動銷23驅動，並且如從圖6和8的對比可以看到，推桿26執行腳抬升軸27的樞轉，該樞轉又被轉換為壓腳桿8在正z方向上的抬升。 Figures 7 and 8 show the main components of the drive assembly 14 in the raised position of the foot. The foot raising position is achieved in that first the auxiliary drive 17 is temporarily driven, wherein the reciprocating piston 24 moves the sliding pin 23 from the rest position according to Figs. 3 and 4 to the foot raised position according to Figs. In the foot raised position, the free driver end 28 of the slide pin 23 is moved into a complementary base formed at the free end of the push rod 26 to form a drive coupling of the slide fork 18 with the push rod 26. The main drive 15 is now driven such that the sleeve piston 16 is pulled together with the slide fork 18 from the rest position to the actuated position. Thus, in the foot up position, the free end of the push rod 26 is driven by the slide pin 23, and as can be seen from the comparison of Figures 6 and 8, the push rod 26 performs the pivoting of the foot lift shaft 27, which is converted again. It is the lifting of the presser foot 8 in the positive z direction.
壓腳桿8的抬升克服壓縮彈簧29的可調節的預張緊力而被執行。 The lifting of the presser foot 8 is carried out against the adjustable pretensioning force of the compression spring 29.
在完成腳抬升之後，主驅動器15移回到其休止位置。一旦推桿26和滑動銷23已通過滑叉18被完全推出，滑動銷23便由於另外的壓縮彈簧30的預張緊而可移回到休止位置，藉此滑動銷23的驅動器端28與滑動桿26分離。 After the foot lift is completed, the main drive 15 is moved back to its rest position. Once the push rod 26 and the slide pin 23 have been fully pushed out by the slide fork 18, the slide pin 23 can be moved back to the rest position by the pretensioning of the additional compression spring 30, whereby the drive end 28 of the slide pin 23 and the slide The rod 26 is separated.
滑動銷23具有釋放凹槽，該釋放凹槽在滑動銷23的腳抬升位置處於旋轉滑動器20的桿端19的高度處。在使滑叉18移位到腳抬升位置時，滑動銷23於是與桿端19相分離，且驅動器部段22不與旋轉滑動器20的桿端19接觸。在腳抬升位置，旋轉滑動器20和用於反轉縫紉方向的裝置12的其它構件都不移動。 The slide pin 23 has a release groove which is at the height of the rod end 19 of the rotary slider 20 at the foot raised position of the slide pin 23. When the shift fork 18 is displaced to the foot raised position, the slide pin 23 is then separated from the rod end 19 and the driver section 22 is not in contact with the rod end 19 of the rotary slider 20. In the foot up position, the rotary slider 20 and other members of the device 12 for reversing the sewing direction are not moved.
滑動銷23因而是可移位的驅動裝置，其在輔助驅動器17的第一驅動位置將主驅動器15的驅動構件16、18聯接到縫紉方向反轉裝置12，而在輔助驅動器17的第二驅動位置將驅動構件16、18聯接到腳抬升裝置13。 The slide pin 23 is thus a displaceable drive which couples the drive members 16, 18 of the main drive 15 to the sewing direction reversal device 12 and the second drive at the auxiliary drive 17 in the first drive position of the auxiliary drive 17. The position couples the drive members 16, 18 to the foot lift device 13.
在聯接已被執行之後，即，在驅動器端28接合在推桿26的相關底座中之後，滑動銷23與輔助驅動器17的往復活塞24分離。輔助驅動器17因而在驅動腳抬升裝置(即致動壓腳桿)時未被涉及，而是僅在不同的聯接位置之間切換時被涉及。滑動銷23被固定在兩個聯接位置而不需要涉及輔助驅動器17。 After the coupling has been performed, i.e., after the driver end 28 is engaged in the associated base of the push rod 26, the sliding pin 23 is separated from the reciprocating piston 24 of the auxiliary drive 17. The auxiliary drive 17 is thus not involved in driving the foot lifting device (i.e. actuating the presser foot), but is only involved when switching between different coupling positions. The slide pin 23 is fixed in two coupled positions without the need to involve the auxiliary drive 17.
腳抬升裝置13被構造成使得它可被手動地致動或借助例如也獨立於驅動組件14的肘節桿致動。為此，推桿26可在隨後不起作用的滑叉18的縱向導向部25中滑動。 The foot lifting device 13 is configured such that it can be actuated manually or by means of, for example, a toggle lever that is also independent of the drive assembly 14. To this end, the push rod 26 can slide in the longitudinal guide 25 of the sliding fork 18 which then does not function.
滑動銷23可借助鎖定機構被固定在根據圖7和8的腳抬 升位置，所述鎖定機構在推桿26從腳抬升位置回位時被抬升回到伸展的開始位置。 The slide pin 23 can be fixed to the foot according to FIGS. 7 and 8 by means of a locking mechanism In the raised position, the locking mechanism is raised back to the extended starting position when the pusher 26 is returned from the raised position of the foot.
在腳抬升期間，主驅動器15相對於輔助驅動器17以短的延時被驅動。這樣，在致動腳抬升操作元件時可有短暫的反應時間。 During the foot lift, the main drive 15 is driven with a short delay relative to the auxiliary drive 17. In this way, there is a short reaction time when the actuating foot raises the operating element.
