Definitions

  • the invention relates to a flat knitting machine with a movable machine slide, to which electrical energy and / or control signals are supplied via at least one trailing cable, with at least one trailing cable holder which can be adjusted parallel to the slider track and which is arranged between the trailing cable end located on the carriage and on the machine frame.
  • the trailing cable holder prevents the trailing cable from sagging to the floor and, in the case of driven trailing cable holders, additional relief of the trailing cable from heavy tensile loads as well as juxtaposition of several trailing cable holders and the associated bending of the trailing cable are avoided.
  • the trailing cable with its freely hanging cable loops can vibrate, which the individual cables or Subject the cable harness of the trailing cable to strong alternating loads and can also lead to the trailing cable swinging out of its plane of movement and to striking against neighboring machine parts.
  • the invention has for its object to provide the arrangement of a trailing cable for the carriage of a flat knitting machine so that the trailing cable loops are prevented from undesirable swinging in any operating state, including a short-stroke operation.
  • the object is achieved according to the invention in a flat knitting machine of the type mentioned at the outset in that at least between the trailing cable end located on the slide and the trailing cable holder in the trailing cable plane, two strings are arranged in a row to support the trailing cable, the total length of which corresponds approximately to the length of the trailing cable loop to be supported.
  • the handlebars each form an adjustable angle with rigid angle legs, with which the trailing cable loops can be connected with play.
  • the trailing cable In the case of relatively strong trailing cables, it is generally sufficient for the trailing cable to be supported at the connecting joint point of the two connecting links which are located within a trailing cable loop and at which advantageously a curved web can be arranged for contacting the trailing cable with the lowest point of a trailing cable loop.
  • the two connected links can each consist of two spaced parallel to each other and on one and the other long side of a trailing cable loop and at their ends coupled to each other by a common hinge axis.
  • the trailing cable loops between the handlebar pairs are particularly good against lateral swinging out of the trailing cable movement plane, and the handlebar linkage itself has increased stability in the trailing cable movement plane.
  • the carriage 10 of a flat knitting machine is shown in three different positions a, b and c of its adjustment path on its carriage path (not visible). Its drive coupling with a drive toothed belt 13 guided over drive and deflection rollers 11 and 12 is by a Link arm 14 displayed. Via this connecting arm 14, a trailing cable 15 is also fed to the carriage 10, which forms the electrical connection of the carriage 10 with a fixed connection point 16 on the machine frame (not shown further). The trailing cable 15 is guided in the middle of its length over a trailing cable holder 17 which is movable parallel to the carriage 10 and is also shown in three different positions a, b and c.
  • the trailing cable holder 17 is also coupled to an endless drive belt 18 which is guided via wheels 19, 20 arranged coaxially with the deflection and drive wheels 11.
  • the diameter ratio of the wheels 11 and 19 or 12 and 20 is chosen so that when the common drive shaft rotates, the drive toothed belt 18 only travels half the way as the drive toothed belt 13. The movement of the tow cable holder 17 thus takes place at half the speed as the adjustment of the carriage 10.
  • the trailing cable 15 is shown in each of the three positions a, b and c of the carriage 10 and the trailing cable holder 17. To differentiate the individual positions, the carriage 10, the tow cable holder 17 and the tow cable 15 are each shown in the position a with a dash-dotted line, in the position b with a solid line and in the position c with a dashed line.
  • the trailing cable holder 17 divides the trailing cable 15 between its two end points 16 on the machine frame and 21 on the carriage into two trailing cable loops hanging downwards. These two trailing cable loops are indicated in the position a of the carriage in FIG. 1 by oblique hatching.
  • the hatching shows a triangle shaped loop shape and not an arcuate curved loop, as should be the case with a completely free-hanging trailing cable.
  • the triangular shape is forced by a support device, which consists of two strings 22 and 23, or 24 and 25, which are lined up on each trailing cable loop and indicated in FIG. 1 by simple lines.
  • the handlebar 22 is articulated at one end to the connecting arm 14 of the carriage 10 at the trailing cable end point 21 and at its other end at the point 26 in an articulated manner to one end of the connecting link 23, the other end of which is connected to the articulation point 27 Trailing cable holder 17 is coupled.
  • the second pair of links 24 and 25 strung together one end of the link 24 is coupled to the articulation point 27 of the tow cable holder 17.
  • connection of the two links 24 and 25 forms an articulation point 28, which corresponds to the articulation point 26, and the other end of the link 25 is articulated at the end point 16 of the trailing cable 15 on the frame of the flat knitting machine.
  • articulation point 28 corresponds to the articulation point 26
  • link 25 is articulated at the end point 16 of the trailing cable 15 on the frame of the flat knitting machine.
  • curved web 29 or 30 against the outside of which the trailing cable 15 comes to rest and which forms a deflection support for the trailing cable 15.
  • FIG. 2 shows an embodiment of the articulation point 27 of the tow cable holder 17.
  • the actual articulation point is formed by an axis 31, on the central part of which a bearing sleeve 32 is arranged, to which a screw clamping device 33 for the tow cable 15 consisting of four individual cable harnesses is fastened.
  • the links 24 and 25, each with one of their ends mounted on the axle 31, in this embodiment each consist of two at a distance from one another and parallel to one another Handlebar webs 24a and 24b or 25a and 25b arranged on both sides of the trailing cable 15.
  • the trailing cable 15 thus extends in both trailing cable loops between the delimitation planes formed by the two link webs of the links 22-25.
  • the trailing cable loops are also caused by a swing in the trailing cable movement plane and also by a lateral swing-out during a rapid short stroke movement of the carriage 10 in the direction of the double arrow 34 shown in FIG. 1 hindered from the plane of movement.
  • the trailing cable 15 can also be loosely connected to the links 22-25 with play at other points, so that a relative movement of the trailing cable 15 relative to the links 22-25 is possible when changing the distance between the articulation points 21 and 27 as well as 27 and 16.
  • the invention is also effective in trailing cables in which no movable trailing cable holders are provided, that is to say the trailing cable only forms a single loop between the carriage and the machine frame.
