Definitions

  • the invention relates to a sewing machine of the type specified in the preamble of claim 1.
  • the drive crank which is pivotably mounted at one end, is pivoted back and forth via a connecting rod which engages at the other end by means of an eccentric of the drive shaft, which rotates synchronously with the main sewing machine shaft.
  • the output crank protrudes radially from the output shaft on which it is attached.
  • One or the other end of the link is articulated to the connecting rod end of the drive crank and to the free end of the output crank.
  • the output shaft has a radial arm, at the free end of which one end of a support bar carrying the sewing material pusher is articulated. At the other end, the support bar interacts with a second eccentric, which rotates synchronously with the first eccentric for the intermittent lifting of the material feeder in time with its intermittent movement in the material feed direction.
  • the pivot axis of the drive crank is adjusted to adjust the length of each movement of the sewing material pusher in the sewing material feed direction and thus the stitch length. If this pivot axis is aligned with the axis about which the handlebar and the output crank are mutually pivotable, then the drive crank and the handlebar pivot about the same axis while the drive shaft rotates and the handlebar cannot move the output crank, so that the output shaft stands still, which is the Stitch length corresponds to 0. The further the pivot axis of the drive crank is deflected from this position away from the drive shaft to the output shaft, which forms the pivot axis of the output crank, the greater the stitch length.
  • the pivot axis of the drive crank is adjusted by means of the stitch length adjustment device, which is one for the drive shaft and one for Output shaft has parallel actuating shaft with a radial arm which carries the pin-shaped pivot axis of the drive crank parallel to the actuating shaft.
  • the stitch length adjusting device can have a manually rotatable adjusting disk which interacts with the adjusting shaft via a linkage, the linkage additionally being able to be actuated by means of a lever which can be pivoted by hand independently of the adjusting disk for seam locking in order to turn the adjusting shaft against the effect of a spring load that the pivot axis of the drive crank moves away from the output shaft via the position corresponding to the stitch length 0, with the result that the material pusher always moves in the opposite direction to the normal material feed direction when raised.
  • an upper and a lower sewing material auxiliary slide can be driven, to each of which an actuating shaft is assigned, which is coupled to the actuating shaft for the sewing material main slide via a linkage, whereby these two linkages can be adjusted in themselves for a specific differential transport to effect the sewing material (DE-A 26 25 152).
  • the stitch length adjusting device can also have a double-acting compressed air cylinder for actuating the adjusting shaft in one and in the other direction, the strokes of which are the same in both directions and can be adjusted according to the desired stitch length by means of an adjusting sleeve which can be rotated by hand on the cylinder housing .
  • the piston rod of the compressed air cylinder is articulated to a radial arm of the actuating shaft (DE-C 29 16 642).
  • the stitch length adjusting device can also have a digitally operating compressed air cylinder for actuating the actuating shaft and a control device for the compressed air cylinder, into which the respectively desired stitch length can be entered by means of a control panel.
  • a lower and possibly an upper sewing material auxiliary slide can also be provided in order to enable differential transport of the sewing material, the lower sewing material auxiliary slide or both sewing material auxiliary slides being driven in the same way as for the main sewing material slide and an additional actuating shaft for the sewing material auxiliary slide or slides, which is provided also by means of a digital air cylinder controlled in the same way is adjustable, which acts on a radial arm of the actuating shaft.
  • the purely mechanical stitch length adjusting device can be assigned to the main sewing material slide instead of said electropneumatic stitch length adjusting device (DE-A 31 18 964).
  • a stitch length adjusting device with an electric stepper motor is further provided in another known sewing machine, which differs slightly from the sewing machines described, in that the drive crank is pivotally mounted on an arm of an angle lever, on the other arm of which the stepper motor engages via a rod to pivot the angle lever and thus adjust the pivot axis of the drive crank. Furthermore, the output crank is rotatably mounted on its pivot axis and provided with a hub, from which an arm projects radially, which, with its fork-shaped free end, engages around a pin at the adjacent end of a crossbar of the material pusher, around this crossbar end on a guide pin extending in the material feed direction to postpone. At the other end, which is adjacent to the material slide, the crossbeam rests with a lower nose on the eccentric for lifting the material slide. An adjusting shaft and an output shaft are missing from this sewing machine (DE-A 33 21 215).
  • the invention has for its object to provide a sewing machine of the type specified in the preamble of claim 1, in which the drive shaft and the output shaft extremely close to each other and the drive crank, the link and the output crank can be arranged symmetrically to one and the same shaft transverse plane, further on simple way direct proportionality between the movement of the actuator associated with the adjustable pivot axis and the resulting change in the movement of the output shaft caused by the drive shaft can be achieved and such a design is possible which allows the transmission ratio between the drive shaft and the output shaft to be simple Way to change.
  • the possibility of being able to arrange the drive shaft and the output shaft at a very small distance side by side in the sewing machine according to the invention proves to be particularly advantageous if it is a blind sewing machine with a bow needle and fabric flexor for bulging the material into the path of movement of the bow needle , and also because their fabric flexor drive shaft can also be used as a material feed drive shaft.
  • the symmetrical arrangement of the drive crank, the handlebar and the output crank with respect to a plane oriented transversely to the drive shaft and the output shaft, which the sewing machine according to the invention also enables, is very favorable with regard to the transmission of power from the drive shaft to the output shaft and prevents the occurrence of dynamic forces.
  • the possibility of being able to change the transmission ratio between the drive shaft and the output shaft makes it possible to assign different maximum stitch lengths and the desired maximum stitch length to the same swivel angle of the drive shaft only by providing the appropriate gear ratio, the maximum stitch length being the upper limit of the range within which the stitch length can be changed and adjusted.
