Definitions
- the invention relates to a sewing machine according to the preamble of Claim 1.
- DE 35 19 729 C2 is a sewing machine with an optoelectronic Edge scanning device known in which the light source via a light guide is connected to a lens.
- DE-C2 is one alternative embodiment explained in more detail and illustrated in the drawing which the light source and the lens without the interposition of a light guide are housed as a light transmitter in a common housing. This The light transmitter is according to the drawing of DE-C2 in the lower middle area attached to the front of the housing head. At this point it is done no free space for the arrangement of the light transmitter available, because there the needle thread coming from the thread feeder runs along.
- the invention has for its object the end portion of a Attach light source connected light guide so that neither the view of the devices located on the front of the housing head hindered, still impaired the handling of the needle thread when threading become.
- the task is characterized by the characteristic features of the Claim 1 solved.
- the thread guide hook As a tube and The thread guide hooks the light guide into this tube an existing component of the sewing machine as Bracket for the end portion of the light guide and the lens used so that there are no problems with a clear view of the front of the head existing devices and thread guides and no complications with regard to the free accessibility to these components.
- the invention is based on an embodiment shown in the drawing explained.
- the machine housing has a base plate 1, a stand 2 and an arm 3, which merges into a head 4.
- a needle bar 5 with a needle 6 in a known manner, a presser bar 7 with a presser foot 8 and one over the Front 9 of the head 4 partially protruding thread feeder 10 stored.
- Devices and thread guides are only the thread tensioning device in the drawing 11 and the thread guide hook 12 shown.
- the work area the needle 6 in the plane of the throat plate 13 forms the stitch formation point of the Sewing machine.
- the thread guide hook 12 is not solid as usual, but as Tubes and thus hollow.
- the free end of the thread guide hook 12 is inclined downwards in the direction of one in the throat plate 13 recessed lens 14 aligned.
- the light barrier contains a light source 15 and one as a light receiver Serving sensor 16. These components are inside the base plate 1 arranged. They are in the drawing only for the sake of clarity shown below the base plate 1.
- the end section 18 of the light guide 17 closes with the free one End of the thread guide hook 12.
- Threaded section 19 On a trained at the free end of the thread guide hook 12 Threaded section 19 is a screw sleeve 20 provided with a counter thread screwed on.
- the screw sleeve 20 carries a lens 21, with the help of the emitted by the light source 15 and passed through the light guide 17 Light beam focused on the lens 14 embedded in the throat plate 13 becomes. By turning the screw sleeve 20, the focusing can be fine-tuned.
- the light beam received by lens 14 is used to enter one second light guide 22, also shown as a dash-dotted line focused and then forwarded to the sensor 16, where it is then in an electrical Signal converted and finally signaling in a known manner is processed further.
