Description

  The present invention relates to a sinker control device, and more particularly to a sinker control device for a flat knitting machine.

  The flat knitting machine controls the process of creating a loop guided by a knitting needle, that is, separating the created loop from the knitting needle, pulling the loop on the knitting needle, and then dropping the loop from the needle tip to create a new loop. In order to do this, a sinker is arranged between the knitting needles. The sinker has an outer edge that protrudes on one side opposite the needle tip of the knitting needle, and when the sinker is rotated, the protruding outer edge presses the yarn hooked by the knitting needle to create a loop, thereby creating a knit product surface. Organize the handle.

  In order to control the rotation operation of the sinker, a control device is provided on one side of the sinker of the flat knitting machine. The sinker control drive device disclosed in Patent Document 1 includes two first cams and second cams arranged adjacent to each other. The first cam and the second cam are respectively supported on the erection bar by two first parallel interlocking bars and two second parallel interlocking bars. Moreover, these cams are connected by an attached interlocking rod. The first parallel interlocking rod, the second parallel interlocking rod, and the attached interlocking rod interlock with each other, control the operation of the first cam and the second cam, and press the sinker located in the first cam and the second cam. This makes the loop of different sizes by changing its rotation angle. The above interlocking structure can also be found in sinker control devices described in other published information such as Patent Document 2, Patent Document 3, and Patent Document 4.

  The operations of the conventional first cam and second cam are controlled by a switching member interlocking with the first cam and the second cam. The switching member switches the position based on the friction force or the magnet force between the needle beds, and drives the first cam and the second cam. Since the distance between the conventional switching member and the needle bed is fixed, the demand for the flatness of the needle bed is increased. If the distance is too large, the switching member cannot perform a switching stroke, and if the distance is small, the frictional force between the switching member and the needle bed increases and is caught on the needle bed.

The elastic member 40 in this embodiment is a spring. When the switching device 35 moves laterally to the step position with respect to the horizontal plate 12, the first end 41 and the second end 42 of the elastic member 40 are in close contact with the switching body 352 and the interlocking device 32 as shown in FIG. Therefore, the elastic member 40 applies a force to the switching body 352 by pressing it in the direction of the horizontal plate 12. As a result, an appropriate contact relationship is maintained between the switching body 352 and the horizontal plate 12, so that the switching body 352 cannot be driven because the distance is too large, or the switching body 352 and the horizontal plate 12 are pressed against each other. The switching body 352 cannot be moved laterally.

  6 and 7 show operation diagrams of one embodiment of the present invention. As shown in FIG. 6, in the start state, the magnetic attracting part 50 on the switching body 352 is attracted to the horizontal plate 12 by magnetism, so that the sinker control device 30 is fixed above the corresponding horizontal plate 12.

  When the sinker control device 30 moves in the R direction with respect to the horizontal plate 12, the magnetic attracting part 50 on the switching body 352 is attracted to the horizontal plate 12 by magnetism at the initial stage of the movement. Only the first control mountain angle 33 and the second control mountain angle 34 move in the R direction, and the first drive rod 331 of the first control mountain angle 33 moves the recovery stage 324 of the first guide rail 321 into the transition stage 323. In order to do this, the first control mountain angle 33 is converted from the recovery position to the settling position. Further, the second drive rod 341 of the second control mountain angle 34 converts the second control mountain angle 34 from the subsidence position to the recovery position in order for the transition stage 323a of the second guide rail 322 to enter the recovery stage 324a. . This is as shown in FIG. As the movement continues, the first drive rod 331 and the second drive rod 341 follow the interlocking device 32 and the switching device 35 disposed on the interlocking device 32, and the interlocking device 32 and the switching device 35 are relative to the basic body 31. Thus, the driving stroke is performed until the interlocking device 32 comes into close contact with the restriction unit 311.

  After that, when the sinker control device 30 tries to move in the L direction with respect to the horizontal plate 12, the magnetic adsorption portion 50 on the switching body 352 is similarly attracted to the horizontal plate 12 by magnetism at the initial stage of the movement. Only the basic body 31 and the first control mountain angle 33 and the second control mountain angle 34 above it move in the L direction. The first drive rod 331 of the first control mountain angle 33 converts the first control mountain angle 33 from the subsidence position to the recovery position so that the transition stage 323 of the first guide rail 321 enters the recovery stage 324. Further, the second drive rod 341 of the second control mountain angle 34 converts the second control mountain angle 34 from the recovery position to the subsidence position in order for the recovery stage 324a of the second guide rail 322 to enter the transition stage 323a. . That is, the state returns to FIG. As the movement continues, the first drive rod 331 and the second drive rod 341 follow the interlocking device 32 and the switching device 35 disposed on the interlocking device 32, and the interlocking device 32 and the switching device 35 are relative to the basic body 31. Thus, the drive stroke in the reverse direction described above is performed until the interlocking device 32 comes into close contact with the limiting portion 311a.

  As described above, since the appropriate contact relationship is maintained between the switching body 352 and the horizontal plate 12 by the sinker control device of the flat knitting machine of the present invention, the movement state of the sinker control device with respect to the horizontal plate is stabilized. Effectively switch the control angle between the settling position and the recovery position. Further, the interlocking device of the present invention is more simplified than the structure of the conventional drive cam, lowers the difficulty of assembly, reduces the production cost, and makes it advantageous to manufacture the flat knitting machine.
