Definitions

  • the subject of the present invention is a rectilinear knitting machine comprising at least one needle bed, at least one cam carriage moving above the needle bed for driving the needles, several striping bars parallel to the needle bed and on each of which a thread guide is slidably mounted between two stop blocks which are also mobile along the striping bar, the thread guide, provided with a thread spout, being driven by fingers integral with the carriage and mounted resiliently so as to be able to be separated from the wire guides by ramps of the stop blocks, means being provided for moving the wire spouts in a direction different from that of the carriage.
  • a displacement of the threads of the thread guides in a direction different from that of the carriage is required when making Intarsia knits, more precisely when changing thread when changing from one color to another color.
  • the thread beak that stops knitting must be pushed aside to make room for the needle that goes up to pick up the new thread.
  • the mechanism described in DE-A 25 55 750 comprises a thread spout mounted oscillating on the thread guide block by means of a system of levers and articulations, the thread guide being provided with two pushers which control the recoil of the thread spout when it meets one of the stop blocks.
  • the recoil of the thread spout is therefore only possible when the thread guide meets a stop block and it takes place before the guide stops. wire.
  • the thread spout is raised by a cam carried by the thread guide, the latter consisting of several moving parts relative to each other, the lifting of the spout being caused by the relative movement of the different elements of the thread guide when the latter encounters a stop block.
  • the construction of the wire guide is relatively complicated and, as in the previous mechanism, the separation of the wire spout can only take place at a precise instant, when the wire guide meets a stop block.
  • the thread spout is also vertically retractable and it is pulled upward on the thread guide by two springs, a piece movable transversely on the thread guide controlling the retraction of the thread guide by means of a cam at the instant when it meets a stop block, that is to say just before the stop of the thread guide.
  • All known systems have in common a more or less complicated mechanism, mounted on the thread guide and ensuring the spacing of the thread spout at the instant when the thread guide meets a stop block and at this instant only, the thread spout being movably mounted on the thread guide.
  • the stop blocks have the exclusive function of a stop.
  • the thread guides can interfere with each other if they are very close to one another, in particular in the case of tilting thread spouts which risk catching a nearby thread spout or thread and to cause an accident.
  • the present invention aims to allow the movement of the wire spouts at any time, independently of the movement of the carriage, that is to say not only when the wire guide meets a stop block.
  • the invention further aims to achieve this object by means as simple as possible.
  • the stop blocks are not used as a stop but as a means of driving the wire guides and the means for positioning the stop blocks are used simultaneously for spacing or retraction thread guides.
  • the stop blocks being driven by auxiliary means, it is possible to move the wire guides with their wire spouts at any time, independently of the movement of the carriage.
  • the mechanism for automatically attaching the wire guides to the stop blocks can be very simply carried out on the model of automatic hooks for coupling railway cars. Unhooking can be carried out very simply by the thread guide finger which lifts the hook before meeting the thread guide nose.
  • the system according to the invention is therefore not only much more flexible, in terms of its use, than previous systems, but it can be produced with an extremely simple mechanism.
  • FIG. 1 schematically represents a rectilinear knitting machine comprising a frame 1 supporting two needle beds 2, 2a arranged in a V in which the needles and their keys are arranged, and a carriage 3 on which are fixed cam holders 4 with double drop, in the example under consideration, each of these falls being symbolized by a triangle A, respectively B.
  • the carriage 3 further carries scratching boxes 5 and 5a corresponding respectively to falls A and B and provided with a drive finger 25, respectively 25a, mounted sliding and elastically vertically in a known manner, for driving wire guides such as 6 and 6a mounted on striping bars 7 arranged parallel to each other in a known manner and supported by supports 8 and 8a. On each of the striping bars 7 is mounted a pair of stop blocks 9, 9a sliding in known manner.
  • the movement of the stop blocks 9 and 9a along the striping bars is ensured by a motor 11 for each of the pairs of stop blocks.
  • This motor 11 drives a cable 13 extending along the corresponding striper bar 7 and passing over two end pulleys 10 and 10a, one of the strands of the cable 13 being fixed to one of the blocks. stop 9 and the other strand to the other stop block 9a.
  • the motor 11 is controlled by a displacement sensor 12 in direct relation with the position reading system of the carriage 3, that is to say the thread guides, the whole being controlled by a microprocessor also controlling the selection of the needles and in which the knitting program is saved.
  • the selection of needles is carried out for example as described in patent CH-A 632 024.
  • Each of the thread guides 6, 6a is provided with a thread spout 21, respectively 21a intended to guide the thread 20, unwound from a fixed spool towards the needles.
  • the wire spout 21 is simply fixed to the wire guide 6 by means of two screws.
  • the wire guide 6 is provided with two pawls 22 and 22a pivoted in the center of the wire guide around an axis 24.
  • Each of these pawls is subjected to the action of a tension spring 23, respectively 23a which tends to maintain the pawls in an oblique position, as shown in the drawing, against a stop not shown.
  • These pawls 22 and 22a project from either side of the block 6 of the wire guide and the projecting ends are in the form of hooks 26, respectively 26a and terminated by a ramp 27, respectively 27a, like certain automatic coupling hooks of railroad cars. This hook cooperates with a pin 29 integral with the cam block.
  • the opposite ends of the pawls 22 and 22a are situated approximately at the same height as the drive noses 30 and 30a of the wire guide 6 intended to be driven by the drive finger 25 .
  • FIG. 1 shows a single carriage, two wire guides and only two stop blocks, but it is obvious that the machine could comprise several carriages, several scraper bars and a greater number of guides. - wires and corresponding stop blocks.
  • FIG. 3 schematically represents the movement of three thread guides 61, 62 and 63 of a machine comprising at least three thread guides, in the case of an Intarsia knitting having three knitted zones of different colors I, II and III.
  • the machine is equipped with a double drop cam holder A and B.
  • FIG. 3a shows a cam holder moving to the left and having passed the knitted piece.
  • the three wire guides 61, 62 and 63 have reached the end of their travel and are all three hooked to the corresponding left stop blocks.
  • Figure 3b shows the cam holder A, B returning to the right for knitting the next row of stitches.
  • the thread guide 63 is moved to the right by means of the left stop block to come into position 63 ⁇ in order to release the knitted part II which will be knitted using thread guide 62.
  • Part I is knitted with the drop A and the thread guide 61 and part II is knitted with the drop B and the thread guide 62, as shown in FIG. 3c.
  • the thread guide 61 meets its right stop block to which it hooks, as shown in FIG. 3d.
  • the thread guide 62 stops and hangs on its right stop block in the position represented in broken lines in FIG. 3d. As soon as the thread guide 62 has reached this position it is brought back, that is to say to the left in position 62 ⁇ by the stop block to which it is hooked to release the part III remaining to be knitted. Simultaneously the thread guide 63 is also moved to the left from position 63 ⁇ to position 63 ⁇ by its left stop block to which it is hooked, in a position corresponding to the position shown in Figure 2, to prepare the knitting of the part III.
  • the displacement of the thread guides 62 and 63 shown in FIG. 3d must take place as soon as the fall B has finished working and especially before the fall A begins to actuate the needles of the knitted part III.
  • Figure 3e shows the thread guide 63 moving to the right when knitting part III with the drop A.
  • the knitting of part III once the thread guide 62 is finished is moved to the right by its right stop block so that the three thread guides are in a similar position to the right of the end of the thread part. matching knitting.
  • the carriage 3 then moves from right to left and it is then the yarn guide 61 which is moved to the left to release part II of the knitted panel and it is then parts II and III which are knitted respectively with falls A and B.
  • the thread guides 61 and 62 are moved to the right to allow knitting of part I with the drop B, and so on.
  • the time available to simultaneously move two neighboring wire spouts is equal to the time it takes the carriage to travel a distance equal to the distance separating the centers of the two falls A and B.
