Definitions
- the invention relates to a sewing machine according to the preamble 5 of patent claim 1.
- a sewing machine of the type mentioned is known from the patent document DE 24 54 116 B2.
- This sewing machine consists of a support surface for two mate rial webs to be sewn together and a sewing device associated with the support surface, which is operatively connected to a machine control, wherein a plate element positioned between the two material webs is arranged in the material feed region thereof.
- a machine control actuated vertical actuator for the plate member is provided, which further provided with a solenoid for position adjustment of the plate member is. From column 5, lines 1 to 4 of said document it follows that the electromagnet is formed as part of a solenoid valve which serves to actuate an air cylinder.
- the invention has for its object to improve a sewing machine of the type mentioned.
- a Sewing machine can be created with the two material webs can be fully automatically sewn together fully automatically even when using different materials and / or non-congruent blanks.
- the plate element 10 is provided with a magnet interacting with the electromagnet.
- the solution according to the invention is thus distinguished by the fact that influence is exerted on the feeding of the two material webs with the aid of the plate element which is adjustable in its distance from the support surface.
- a reduction of the distance in particular causes the material layer between the support surface and the plate element is braked.
- the Ab 20 Standes resting on the plate member ie the upper material layer against the presser foot or a further to be explained in more detail below abutment and thus also braked.
- this gives rise to the possibility of influencing the supply of the two material webs to the sewing device in a practically continuous manner, and thus ultimately their position relative to one another during sewing together.
- FIG. 1 in perspective, the sewing machine according to the invention with 15 the height-adjustable plate member;
- the sewing machine shown in Figure 1 consists first in a known manner from a preferably horizontally oriented support surface 1 for two fauxzuähende webs 25 and one of the support surface 1 associated, with a typical electronic working machine control 2 operatively connected sewing device 3, wherein in the Materialzu slaughter Scheme one between the two Material webs positioned plate member 4 is arranged.
- a typical electronic working machine control 2 operatively connected sewing device 3, wherein in the Materialzu slaughter Scheme one between the two Material webs positioned plate member 4 is arranged.
- a region B of the plate element 4 contacted during the sewing of the material webs has a width B between 50 and 100 mm, a depth T between 20 and 70 mm and a thickness D between 5 1 and 5 mm.
- the so-called presser foot can serve as an abutment for the plate element 4, for example. More generally, it is particularly preferred according to the invention that the plate element 4 is arranged between the support surface 1 and an abutment 9.
- the sewing machine according to the invention for rotating the upper material web about a vertical axis (or in a horizontal plane) above the support surface 1 is particularly noteworthy.
- the upper guide element 11 forms the aforesaid abutment 9 for the plate element 4.
- a form-adapted abutment surface 4.4 for the upper guide element 11 is more preferably provided on the plate element 4.
- partial ring-shaped expresses the fact that the upper and / or lower guiding element can also be designed as a solid ring.
- the lower guide element is formed as a solid ring and the upper guide element as a partial ring.
- the vertical adjusting device 30 5 is provided with an electromagnet 6 for adjusting the position of the plate element 4 and, which is essential to the invention, the plate element 4 with a cooperating with the solenoid 6 magnet 8, in particular permanent magnet provided.
- the vertical adjusting device 5 is preferably additionally provided with a permanent magnet 7, wherein the permanent magnet 7 of the vertical adjusting device 5 between the electromagnet 5 gnet 6 of the vertical adjusting device and the plate member
- the preferably formed by an iron ring 12 formed magnet 8 on 10 plate member 4 and the permanent magnet 7 of the vertical adjusting device 5 in a repelling position (ie with the same poles) are arranged to each other. Furthermore, it is preferable between the permanent magnet 7 of the vertical adjusting device
- an immutable 15 gnetisierbare separating layer 13 is arranged in order to exclude an undesirable, because difficult to solve direct contact of the magnets together.
- the vertical positioning device 5 to adjust the vertical distance between the bearing surface 1 and two different ones Areas 4.1, 4.2 of the plate member 4 25 is formed, wherein the two areas 4.1, 4.2 of the plate member 4 are particularly preferably on both sides of an imaginary, parallel to the material feed direction and a needle of the sewing device 3 ending line are arranged.
- the plate element 4 preferably has a region 4.3 which is not affected by sewing the material webs together, and is connected to the support surface 1 (laterally) by a holding element 10 which is preferably designed as a vertical guide.
- a rotation of the plate element 4 about a vertical axis preventing locking device 14 is preferably arranged between the support surface 1 and the plate member 4.
- the sewing machine according to the invention works as follows:
- the two sixteenzu cafetun material webs which are often made of different materials, for example, 20 in car seats are basically inserted as usual in the sewing machine, with the only difference that the lower material web between the support surface 1 and the plate member 4 and the upper material web between the Plate element 4 and the Wi- 25 derlager 9 (here the upper guide member 12) is positioned.
- a material edge detection device provided or arranged on the sewing machine in a known manner detects the edges of the material webs provided with markings (so-called knapsons), which are positioned correspondingly accurately when being inserted at the beginning of the seam 30. If the sewing process is now started, the edges are continuously recorded with the aid of the material edge detection device.
- the plate member 4 is actuated according to 5 with the aid of the vertical adjusting device 5, whereby either the upper or the lower material web braked and further with the help of the two areas 4.1, 4.2 of the plate element in to steer a desired direction.
- the holding member 10 ensures that the plate member 4 is basically designed to be vertically adjustable, in addition, the rotation 14 ensures that the plate member 4 can not be rotated about the vertical axis of the support member 10. 15
- the signal of the material edge detection device is correspondingly evaluated and a suitable signal for controlling the or both electromagnets 6 is calculated, which then leads to the upper or the lower material web being braked in the respective region 4.1 or 4.2.
- the electromagnets 6 can even be driven in opposition to one another. All this makes it possible, as has been shown by corresponding operator-side tests, that the material webs can be sewn together very precisely along their edges.
