Definitions

  • pivoting design of the material holder increases the technical effort of the feed device.
  • a pivotable sewing material holder is particularly disadvantageous in the case of large pieces of sewing material, since these are subject to additional displacement forces during pivoting movements and require a larger contact surface.
  • Fig. ⁇ 1 is a side view of a sewing machine
  • a frame is shown, the table top (1) is used to hold a sewing machine (2).
  • the housing of the sewing machine (2) consists of a base plate (3), a stand (4), an upper arm (5) with a swivel-mounted head (6) and a lower arm (7) with a swivel-mounted hook bearing (8).
  • a swiveling Through the head (6) and the gripper bearing (8) a swiveling
  • the head (6) carries a needle bar (10) with a needle (11) and a presser device (12).
  • a throat plate (13) (FIG. 2) is received in the base plate (3).
  • a shaft (14) is mounted on the upper part of the stand (4) and a shaft (15) on the lower part. Both shafts (14 and 15) are driven by a stepper motor (16) which is controlled by a control device (not shown) of the sewing machine (2).
  • a control device not shown
  • a pulley (17) is attached to the upper end of the shaft (14) and is connected via a belt (18) to a pulley (19) attached to the head (6) in a rotationally fixed manner.
  • a belt wheel (20) at the lower end of the shaft (15) is via a belt (21) with a
  • One end of the output shaft (63) has a pin (64) formed eccentrically to the shaft axis.
  • the pin (64) is gripped by one end of an eccentric rod (65), the other end of which is connected via a pin (66) to a handlebar stitch actuator (67) designed in the usual way.
  • a rocker (68) also acts on the pin (66), the other end of which is articulated to the pin (36) of the needle bar carrier (31).
  • a feed device (69) shown in FIG. 4 is arranged on the table top (1).
  • the rotation of the motor shaft (25) drives the toothed belt wheel (26), the rotation of which is used via the eccentric rod (28) to drive the needle rod (10).
  • the rotary movement of the toothed belt wheel (26) is used to drive the toothed belt wheel (45) and thus the shaft (46) via the toothed belt (44).
  • the needle bar carrier (31) runs through only half the stitch width during a needle bar stroke. With this setting, the needle (11) enters and exits the material at both reversal points of the needle bar carrier (31).
  • the sewing machine (2) then works with zigzag operation for zigzag seams.
  • the sewing material holder (71) is moved by the feed device (69) by correspondingly controlling the stepper motors (74 and 84) from its rest position shown in FIG. 4 to the sewing position, where the point at which the seam is to begin is under the needle (11).
  • the head (6) and hook bearing (8) of the sewing machine (2) are in a neutral starting position as shown in FIG. 1, in which the transverse movement of the needle bar carrier (31) takes place in a plane perpendicular to the plane of the drawing. Then the sewing machine (2) is switched on and the gear (49) of the seam to be formed is adjusted accordingly.
  • the head (6) is pivoted by appropriate control of the stepping motor (16) via the belt (18) so that the transverse movements of the
