Definitions

  • ABSTRACT Automatic cam setting device arranged on knitting machines at the end of carriage travel and including a fixed pin which engages and flips a lever on the carriage to loosen a cam which is then positioned as the carriage and cam move over a cam setting device. The cam is locked in its new position as the carriage moves in the opposite direction.
  • SHEET 3 or 4 1 METHOD AND APPARATUS FOR ADJUSTING STITCH CAMS
  • This invention relates to method and apparatus for setting stitch cams on knitting machines, particularly those stitch cams which are present on flat knitting machines.
  • the setting of these stitch cams serves to control the firmness of knitting.
  • This object is achieved, according to the present invention, by effectingthe adjustment of one or more stitch cams for one or more carriages, from an adjusting device which is located outside the cam carriage.
  • the stitch cams are clamped during the stitching process of the machine, are released before their adjustment and are then clamped again after adjustment.
  • an adjusting member of the adjusting. device acts directly on the lowermost surface of the stitch cam.
  • the adjusting device can be controlled. mechanically, pneumatically or electrically.
  • Apparatus in which the present invention is embodied is characterized by the fact that the adjusting device has a setting member arranged laterally on the outside of the knitting machine with a corresponding actuating member and that a clamping device is provided on the cam carriage.
  • the setting member there may be provided a switchable bar on which, in individual switch steps, fine-adjustable setting plates are arranged.
  • an electric motor is provided for adjusting the setting member. This electric motor can be arranged to be controlled by an electric displacement pickup and an electric adjusting device for the setting device.
  • the electric adjusting device is preferably a potentiometer.
  • an electromagnet is provided with an eccentric lever for clamping of the stitch cams.
  • FIG. 1 is a top view of a portion of a stitch cam lock in which only a stitch cam with a cam clamping device is shown;
  • FIG. 2 is a section view taken along line 2-2 of FIG. 1;
  • FIG. 3 is a partial section view taken along line 3-3 of FIG. 1;
  • FIG. 4 is a view similar to FIG. 3, but showing another embodiment of a stitch cam clamping device
  • FIG. 5 is a plan view of a mechanically actuated setting device used to establish the position at which the stitch cam is clamped;
  • FIG. 6 is a plan view of an electrically actuated setting device
  • FIG. 7 is a schematic view of a flat knitting machine with an attached stitch cam setting device.
  • a stitch cam 1 (shown in dashed outline) travels by means of its guide block 2 in a guide slot 3 of a cam box 4 and is held down by a cover plate 5.
  • a tension spring 6 pulls the stitch cam l downward.
  • Above the cover plate 5 is a clamping angle 7 through which a clamping bolt 8 threaded at its upper half 9 extends.
  • a clamping nut 10 is screwed onto the threaded half 9 of the bolt 8.
  • the nut 10 is fashioned into the configuration of a shift lever having two switch lever arms 11 and Ila.
  • the clamping can also be effected by an eccentric lever 17 which is actuated by an electromagnet l8.
  • the switch lever arm 11 Upon further movement of a carriage 38 in the direction indicated by the arrow of FIG. 1, the switch lever arm 11, which is mounted on the carriage, strikes against a limiting pin 19 and presses the switching slide 12 away from the lock. This allows the cam block 4 to continue its movement in the direction of the arrow B while the lever arm 11, now in its loosened position, passes under the pin 13 which is urged upwardly, along with the slide 12, over the end of the lever arm 11. After the passage of the switch lever arm 11, the switching lever 12 springs back into its basic position shown in FIG. 1. After the reversal of the carriage into the opposite direction of travel, the switch lever arm 11 is swung to the left against a limiting pin 20 and again clamps the switch cam 1 fast.
  • the switch lever arm 11a and the switch slider 12a are provided with switch pins 13a, as shown in FIG. 7.
  • the clamping of the stitch cam l is released before it comes onto an incline 29 or 30 of the setting slide 15 and is clamped when upon the return of the carriage 38 the lowermost edge 31 of the stitch cam l is, as shown in FIG. 5, on the upper edge 32 of the setting slide 15.
  • step of adjusting the cams is carried out by causing an adjusting member of the adjusting device to act directly on the lowermost surface of the stitch cam.
  • a device for setting the stitch cams on knitting machines comprising, on a knitting machine, a set member fixed laterally on the outside of the knitting machine and having means for adjusting the position of said set member, a cam clamping device on the carriage of said machine, and means on said machine for releasing said clamping device when said cam carriage is at a position to bring a cam thereon into setting engagement with said set member.
  • a device wherein the means for adjusting the position of said set member comprises a switchable bar, and a plurality of fine-adjustable setting plates arranged on said bar individual switch steps.
  • a device wherein said means for adjusting the position of said set member further includes an electric displacement pickup and an electric adjustment device by which the electric motor can be controlled.
  • said electric adjustment device is a potentiometer.
  • a device wherein there is provided an electromagnet having an eccentric lever for the clamping of the stitch cams.
