Definitions

  • Sewing machines of the type mentioned in the preamble of claim 1 have been known for a long time and have already been described in German patent 13 364 (1880).
  • the well-known hopper feeder which mostly interacts with a bouncing top feeder, serves as the lower material pusher, both transports now gripping the work piece in an intermittent manner and moving in rhythm with the needle movement. You can change the feed size of one, usually the upper feeder, independently of the other feeder. This can be achieved that sections of a fabric layer can be dammed up with the purpose, for. B. Incorporate fullness.
  • the invention has for its technical object to provide a sewing machine with continuously driven upper and lower fabric slides, which operate at different transport speeds in order to maintain the fabric width.
  • the outline of a sewing machine e.g. B. an industrial high-speed sewer, which - apart from the subject of the invention, the controlled drive of the fabric pusher - is of conventional design.
  • the slider for the workpiece 2 (Fig. 1) are described in more detail, upper and lower belt transports 12, 20, which receive their driving force from the arm shaft 3 via several intermediate shafts and gears.
  • Of the arm shaft 3 only its outer stub shaft is shown, on which the pulley 5 and the usual handwheel 7 are seated.
  • the drive of the shaft 3 is carried out by a drive belt, not shown, via the pulley 5, which in turn is driven by a sewing machine motor, also not shown.
  • the torque of the arm shaft 3 is transmitted through a reduction gear 4 to the higher shaft 6.
  • the shaft 6 is connected by a pin 8 to the housing 9 of a differential gear of known construction.
  • the bevel gear 13 of the differential gear is fixedly connected to the shaft 10, while the bevel gear 14 opposite the bevel gear 13 is arranged to move freely on the shaft 10 and is positively connected to a belt pulley 15 via the shoulder 14 '.
  • the belt pulley 15 drives the lower belt transport 20 p n via the belt drives 16 and 17 with the interposition of the shafts 18 and 19.
  • the upper belt conveyor 12 and the lower belt conveyor 20 are driven at the same speed.
  • the four bevel gears in the differential do not rotate on their axes.
  • the differential gear acts like a rigid connection, with a direct torque transmission from shaft 6 to shaft 10 and shaft 18.
  • a friction wheel transmission is used to adjust the speed, consisting of the friction disk 24 firmly connected to shaft 10 and the friction disk 25 firmly connected to shaft 18, which are parallel to one another and which are connected to one another in a contact-locking manner by the smaller friction disk 26 which is perpendicular to them.
  • the friction wheel transmission known per se is shown in FIG. 1 in its neutral position, i.e. that the same torque is transmitted from the shaft 6 to the shafts 23, 18 and 19 and that both belt transports are driven at the same speed.
  • the friction disc 26 is located exactly at the center of the distance from the shaft 10 to the shaft 18.
  • the friction disc 26 which is designed as a sliding wheel and is mounted on the spindle 27, can be moved up or down after turning the adjusting knob 28 . It is functionally essential for the friction gear that the shaft 18 is axially displaced under the influence of the spring 29.
  • the speed change that occurs after displacement of the friction disk 26 exerts a reaction on the differential gear, so that in a known manner there is a movement compensation by slightly rotating the four previously stationary bevel gears 13, 14, 21 and 22. This results in the fact known for a differential gear that the speeds of the shafts 10 and 18 now behave inversely proportional to one another, ie when z. B. the shaft 10 rotates faster, the speed of the shaft 18 is lower in the same ratio.
  • both belt transports 12 and 20 can be changed in inverse proportion to one another, so that the incorporation of fullness can be carried out easily and reproducibly with rapidly adjustable values, the respective setting being unchanged due to the stabilizing effect of the friction gear preserved.
