Definitions
- the invention relates to a sewing machine according to the preamble of claim 1 and a gripper system for a sewing machine according to the preamble of claim 13.
- the control cam is rotatably connected to the transmission shaft and is directly driven by this with respect to the rotational speed of the gripper only half the speed.
- the control cam is formed on an axial cam as an end face cam surface against which the button is pressed.
- the invention is therefore based on the object, a sewing machine and a gripper system for a sewing machine in such a way that the design complexity for the design of the gripper system is reduced.
- Fig. 1 illustrated double lockstitch sewing machine has in a conventional manner an upper arm 1, a vertical stand 2 and a lower housing-like base plate 3.
- an arm shaft 4 is mounted, via which a needle bar 5 with needle 6 up and down driven. Furthermore, a thread lever 7 is driven by it.
- a vertical gripper 8 that is a about a vertical axis 9 rotatably driven double lockstitch gripper 8, stored.
- a gripper drive shaft 10 carrying the gripper 8, which can be driven about the axis 9, is rotatably mounted in a gripper bearing housing 11 arranged in the base plate 3. It is driven by means of a transmission shaft 12 by means of a bevel gear 13.
- the transmission shaft 12, in turn, is driven by the arm shaft 4 by means of a toothed belt drive 14.
- the toothed belt drive 14 has a transmission ratio of 1: 1.
- the bevel gear 13 is dimensioned such that a gear ratio of 1: 2 is realized. This means that the gripper 8 rotates twice when the arm shaft 4 and the transmission shaft 12 one turn.
- the large bevel gear 15 attached to the transmission shaft 12 has twice the number of teeth as the output bevel gear 16 attached to the gripper drive shaft 10.
- a tap hole plate 17 with a tap hole 18 is attached to the top of the base plate 3.
- the pot-shaped gripper 8 has a gripper tip 19, which passes directly to the immersed by the needle hole 18 needle 6 and can take a guided in this needle thread 20.
- a bobbin case 21 is mounted, which is freely rotatable about the axis 9 relative to the gripper 8.
- the also upwardly open bobbin case 21 has a radially to the axis 9 outwardly and the tap hole plate 17 upwardly projecting retaining web 22 which is held between two formed on the underside of the tap hole plate 17 cams 23, 24 substantially non-rotatable.
- Fig. 2 can be removed, located between the first cam 23 and the holding web 22, a first lateral air gap 25, between the holding web 22 and the needle plate 17, an upper air gap 26 and between the holding web 22 and the second cam 24, a second lateral air gap 27.
- the air gaps 25, 26, 27 form at the in Fig. 2 shown center position of the holding web 22 a continuous channel.
- a bobbin thread 28 receiving coil 29 is arranged, which is held in the bobbin case 21 by means of a releasable locking lever 30.
- the bobbin case 21 has at its upper edge on a substantially radially to the axis 9 outwardly projecting fan cam 31, which cooperates with a fan lever 32.
- the fan lever 32 forms an arm of a capsule fan 33.
- the capsule fan 33 has a fan shaft 34 which is mounted rotatably or pivotably in the gripper bearing housing 11 about a vertical axis 35 parallel to the axis 9.
- the capsule fan 33 further comprises a tactile lever formed as a button 36 and is acted upon by a return spring 37 which acts on the fan lever 32 in the direction of the fan cam 31 out.
- control disk 39 At the gripper drive shaft 10 facing bottom 38 of the gripper 8, a flat disc-shaped control disk 39 is arranged, which has on its outer circumference a control cam 40 against which the button 36 under the force of the return spring 37 is constantly applied.
- This in Fig. 4 shown control disk 39 may be integrally formed with the gripper 8, so be made together with this one-piece. But it can also - as in the Figures 5 and 6 indicated - be plugged on the gripper 8. It is in this case rotatably connected to the gripper 8 by means of a driving pin 41 and positioned in its angular position relative to the gripper 8.
- a plurality of only indicated holes 41a may be formed in the underside 38 of the gripper 8 and / or in the control disk 39 at a small distance from one another, into which the driver pin 41 is inserted, so that an angular adjustment of the control disk 39 and thus the control cam 40 relative to the gripper 8 is reached.
- the thickness a of the control disk 39 and thus of the control cam 40 in the direction of the axis 9 is very small. It is 2.0 mm ⁇ a ⁇ 5 mm.
- For the extension b of the probe 36 in the direction of the axis 9 is that it must be slightly less than the thickness a. Insofar, 1.5 mm ⁇ b ⁇ 4.0 mm.
- the gripper 8 with gripper drive shaft 10, control disk 39 with control cam 40, coil capsule 21 and capsule fan 33 forms a gripper system.
- the mode of action is as follows:
- the cam 40 has a maximum 42 and this approximately opposite a minimum 43, ie a maximum or minimum distance to the axis 9, on. If the button 36 is stirred over the minimum 43, then the fan lever 32 is correspondingly not deflected. He has accordingly Fig. 7 the deflection is zero. This corresponds to a first position 44 of the fan lever 32. Accordingly, the coil capsule 21 is pivoted as far as possible against the direction of rotation 45 of the gripper 8. In other words, this means that the second air gap 27 has its smallest possible width. Accordingly, the first air gap 25 has its maximum width of about 1.5 mm.
- an intermediate portion 48 is formed, in which the control cam 40 has an approximately circular cylindrical course concentric to the axis 9 of the gripper shaft 10, ie approximately constant distance to the axis 9, has. If the pushbutton 36 is guided over this intermediate region 48 of the control cam 40, there is substantially no pivoting movement of the pushbutton 36 and, correspondingly, no pivotal movement of the fan lever 32.
- This intermediate region 48 corresponds correspondingly in the development Fig. 7 the second position 49 marked there. This intermediate region 48 begins approximately when the holding web 22 still has a distance from the first cam 23 of approximately 0.1 mm.
- the embodiment according to the FIGS. 8 to 12 is different from the one after the FIGS. 2 to 6 essentially in that the capsule fan 33 'is pivotable about a horizontal axis 35' extending perpendicular to the axis 9. While in the embodiment of the FIGS. 2 to 7 the fan lever 32 and the button 36 in the same direction, that are pivoted in the same direction, is in the embodiment of the FIGS. 8 to 12 the fan lever 32 'in the opposite direction to the button 36' pivoted. This is due to the fact that the horizontal fan shaft 34 'between the fan lever 32' and the button 36 'in a mounted on the gripper bearing housing 11' bearing 50 is mounted.
- the capsule fan 33 by means of a return spring 37' loaded, the push button 36 'against the control cam 40' of the control disk 39 'presses.
- the control cam 40 ' has a maximum 42', a minimum 43 'and an intermediate region 48', resulting from the opposite pivoting of the fan lever 32 'and button 36' that when crossing the maximum 42 'with the button 36 'of the fan lever 32' is not deflected. He has accordingly Fig. 12 a deflection zero. This corresponds to the first position 44. When passing over the intermediate region 48 'results in the second position 49 of the fan lever 32'. When passing over the minimum 43 'then finally results in the third position 46th
- the pushbutton 36 ' carries out a small movement parallel to the axis 9 in the case of pivoting in addition to the movement radial to the axis 9, the following applies for the thickness a' of the control disk 39 'with control cam 40': 3.0 mm ⁇ a ' ⁇ 5.0 mm.
- the extension b 'of the touch lever 36' in the direction of the axis 9 1.5 mm ⁇ b ' ⁇ 3.5 mm.

In der Grundplatte 3 ist ein Vertikal-Greifer 8, das heißt ein um eine vertikale Achse 9 drehantreibbarer Doppel-Steppstich-Greifer 8, gelagert. Eine den Greifer 8 tragende Greifer-Antriebs-Welle 10, die um die Achse 9 antreibbar ist, ist in einem in der Grundplatte 3 angeordneten Greiferlager-Gehäuse 11 drehbar gelagert. Sie wird mittels einer Ubertragungs-Welle 12 mittels eines Kegelrad-Getriebes 13 angetrieben. Die Übertragungs-Welle 12 wiederum wird mittels eines Zahnriementriebes 14 von der Armwelle 4 angetrieben. Der Zahnriementrieb 14 weist ein Übersetzungsverhältnis von 1:1 auf. Das Kegelrad-Getriebe 13 ist derart bemessen, dass ein Übersetzungsverhältnis von 1:2 realisiert ist. Dies bedeutet, dass sich der Greifer 8 zweimal dreht, wenn die Armwelle 4 beziehungsweise die Übertragungs-Welle 12 eine Umdrehung ausführt. Um dies zu realisieren, weist das an der Ubertragungs-Welle 12 angebrachte große Antriebs-Kegelrad 15 die doppelte Zähnezahl auf wie das an der Greifer-Antriebs-Welle 10 angebrachte Abtriebs-Kegelrad 16.In the
