Definitions

  • the invention concerns a sewing machine capable, in one operational cycle, of loosely sewing on by blind stitching of a button to a workpiece and winding threads around the thus formed post.
  • a program member driven by the main drive shaft controls a button clamping and turning device, the sewing mechanism proper, the reciprocation of a work-Supporting plate and a work-gripping device which is positively coupled to the button turning shaft in the direction of work movement but which is independent thereof in other directions.
  • buttons are sewn on so that during sewing a gap is formed, e.g., with a spacer plate, between the work or fabric and the button.
  • the threads running between the loosely sewn button and the work, called post or stem" then have threads wrapped or wound round them.
  • sewing of buttons is performed with per se known button sewing machines, while the post winding is performed with similarly per se known post winding machines. That is to say, two separate machines are used for button sewing and post winding.
  • This invention aims to provide a machine which performs the button sewing with blind stitching, then after turning the sewn-on button from a button-sewing to a post-winding position, it winds thread round the post, while eliminating the disadvantages of existing machines.
  • a sewing machine for the production in one operational cycle of button sewing with blind stitching and post winding, comprising a main drive shaft, a program control member positively coupled to the main drive shaft, a button clamping and turning device connected by a transmission to the control member for turning the button by at least 75 between a button sewing position and a post winding position, means connected to the control member for effecting the button sewing and post winding, a work-supporting plate connected for reciprocating movement to the control member, the button clamping and turning device being mounted on a button turning shaft journalled on the worksupporting plate, and a work-gripping device which is positively coupled with the button turning shaft in the direction of work movement but which is movable in the directions of work gripping and button turning independently of the button turning shaft.
  • FIG. 1 schematically illustrates the kinematic layout of a combined button sewing and post-winding machine according to the invention
  • FIG. 2 is a fragmentary view in perspective on an enlarged scale of a portion of the apparatus shown in FIG. 1;
  • FIG. 3 is a fragmentary view in perspective of a portion of the sewing machine of the invention at the location of the button sewing station.
  • the machine has a main drive shaft 1 for driving the sewing mechanism.
  • the main shaft 1 receives its drive in the usual way from a round belt or a V-belt, not shown.
  • a cranked driving device located at one end of the main shaft 1 provides the usual vertical alternating drive for the needle bar.
  • the lateral swing of the needle bar is controlled by a cam disc 4 through an adjustable lever mechanism.
  • the machine has a button clamping device 8 which also receives its drive for linear movement in the direction of the main shaft 1 and for button turning between a button sewing and a post winding position from cam disc 4.
  • the cam disc 4 is adapted to be driven from the main shaft 1 via a worm 2 and a worm wheel 3.
  • the cam disc 4 has an internal button turning recess, near the top of the disc 4 as viewed, in which is fitted a roller secured on a one-armed level 5 which transmits its movement according to the shape of the recess to a cranked shaft 7 via a ball-jointed rod 6, so as to turn the device 8 by at least but preferably by a full quartertum.
  • the button clamping device 8 is adjustably secured on the shaft 7.
  • the end of the arm 10 remote from the gauge plate 9 is secured to a base plate 9a connected with the gauge plate 9, so that the work of the work gripping device is independently movable of the button clamping device 8 in the direction of the work gripping movement of the arm 10 and of the button turning movement of the device 8.
  • the base plate 9a, and thus the gauge plate 9 are reciprocatable in a direction substantially parallel with the shaft 7 by virtue of a cammed connection with the cam disc 4, as shown in the drawing.
  • the base plate 9a provides journalled supports for the shaft 7.
  • the appropriate shaping of the groove in the control drum l9 ensures that the cutting of the thread for a lock stitch takes place in the region of maximum speed of movement of the blade holder 23.
  • the withdrawal of the severed thread is controlled by a thread tensioning control claw 25 on the outer surface of the cam disc 4 via a two-armed lever 26 looking a thread tensioner 27 in such a manner that the per se known needle-bar thread drawing mechanism can only pull the span of the thread on the side of the needle after actuation of the thread tensioner 27, since the thread limb on the bobbin side is clamped by the thread tensioner 27.
  • the thread guide 28 is constructed in the form of a mechanism which, in addition to its known swinging movement, can also move axially by virtue of the gearing and connection shown schematically in the drawing.
  • a lifting arm 29 raises the roller 11 from the arm 10 of the work gripping device.
  • the arm 10 will rise under the action of a spring 30, whereafter the work can be removed and replaced by fresh work.
  • the machine has a button clamping device 8 which receives its drive both for linear movement in the direction of the main shaft 1 and for button turning between a button sewing and a post winding position from cam disc 4.
  • the cam disc 4 is adapted to be driven from the main shaft 1 via a worm 2 and a worm wheel 3, the latter being mounted on a shaft 33.
  • the cam disc 4 has an internal button turning recess, near the top of the disc 4 as viewed, in which there is fitted a roller secured on a one-armed lever 5 which transmits its movement according to the shape of the recess to a shaft 7 via a ball-jointed rod 6 (FIGS. 1 and 2) or a rack-toothed wheel engagement (FIG.
  • the button clamping device 8 is adjustably secured on the shaft 7. Its adjustment varies the distance between the button and the work (fabric) and thus varies the length of the post.
  • a work gripping or clamping device comprising a cammed arm 10 coupled to a compression spring 12 via a roller 11.
  • the arm 10 is pivoted to the base plate 9a so that the work gripping device is independently movable of the button clamping device 8 in the direction of the work gripping movement of the arm 10 and also of the button turning movement of the device 8.
  • the base plate 9a is reciprocable in a direction substantially parallel with the shaft 7 by virtue of a cammed connection with the cam disc 4, as shown in the drawing.
  • the base plate provides journalled supports for the shaft 7.
  • a sewing machine for the production in one operational cycle of sewing a button on a work piece including blind stitching and post winding comprising a main drive shaft, a multi-lobed program controlling disc positively coupled to the main drive shaft, a transmission connected to the main drive shaft, a button clamping and turning device connected to the transmission so as to turn the button by at least between the button sewing position and a post winding position, means connected to the control member for effecting the button sewing and post winding, a work-supporting plate connected to the control member for reciprocating movement, a button turning shaft journalled on the work piece supporting plate and carrying the button clamping and turning device, and a work piecegripping device which is positively coupled with the button turning shaft in the direction of work piece movement but which is movable in the directions of work piece gripping and button turning independently of the button turning shaft.
