Definitions

  • the subject of the present invention is a straight knitting machine comprising two needle beds, at least one pair of opposite cam holders for driving the needles, means for driving these cam holders along the needle beds, several thread guides. likely to move on bars above the needle beds, means for driving these thread guides and means for controlling the movements of the cam holders and thread guides.
  • Such a machine is known, for example, from patent application EP 0 415 512.
  • the cam holders are mounted on a carriage in the form of an arch overlapping the needle beds and the line bars on which the wire guides move.
  • Such a form of carriage has been used practically since the invention of knitting machines with two needle beds and has so far been considered as a compulsory design, in order to ensure the synchronized movement of the two cam holders, despite the drawbacks that it presents for an Itarsia knitting machine.
  • These drawbacks lie in the fact that the knitting yarns must be brought to the yarn guides almost horizontally so as not to be in the path of the carriage. For this purpose, the wires must pass over references at one of the ends of the machine.
  • the DUBIED house sought to solve this problem by lengthening the carriage arc transversely.
  • the carriage arc extended in the extension of the machine, considerably increasing the size of the machine.
  • a similar construction is found in the machine described in document US-A-3,733,856, a machine in which the cam holders are each provided with a longitudinal bar, these bars being connected by a transverse bar.
  • Such a machine requires a working space equal to almost twice the width of a machine equipped with conventional carriages.
  • the inertia of the moving assembly is high, which limits the working speed of the machine.
  • the cam holders being rigidly linked together, a relative movement of the cam holders between them is not possible.
  • the object of the present invention is to obviate the drawbacks described above and to propose a construction making it possible to considerably increase the working speed of the machine, as well as the number of knitted threads.
  • the knitting machine according to the invention is characterized in that the cam carriers of each pair are independent and that they are driven individually and mutually controlled.
  • the knitting machine according to the invention therefore practically no longer has a carriage and, contrary to the ideas acquired, synchronization of the cam holders is perfectly possible without rigid connection between these cam holders.
  • the mutual control of the cam holders can be ensured by mechanical or electronic means.
  • the thread guides are preferably driven individually, each by its own motor, which makes it possible to position the thread guides at will and hence the creation of new mesh structures, as well as the combination of different structures and Intarsia.
  • Figure 1 schematically shows a front view of a knitting machine.
  • Figure 2 is a sectional view along II-II of Figure 1.
  • the knitting machine shown comprises, like the usual machines, a frame 1 carrying two needle beds 2 and 3 mounted in V.
  • a frame 1 carrying two needle beds 2 and 3 mounted in V.
  • needles and keys whose driving is ensured by two cam holders 4 and 5, double fall in the example considered.
  • the cam holders 4 and 5 are not mounted on a carriage, but are independent.
  • the cam holder 4 is slidably mounted on two parallel bars 6 and 7.
  • the cam holder 5 is mounted on two parallel cylindrical bars 8 and 9.
  • the cam holder 4 is attached to a toothed belt 10 s' extending over almost the entire length of the machine.
  • the toothed belt 10 is driven by a toothed wheel 11 which is itself driven by a first electric motor 12.
  • the cam holder 5 is attached to a second toothed belt 13 driven by a toothed wheel 14 which is itself driven by a second motor 15.
  • the toothed belts pass over references 16. These references can also be toothed. So as to have two toothed belts 10 and 13 perfectly identical, these belts are preferably obtained by sharing a notched belt along. The belts obtained are thus perfectly identical, both in shape and in structure. They therefore have in particular the same elasticity characteristics.
  • each of these bars 17 to 22 is slidably mounted a thread guide 25, respectively, 26, 27, 28, 29, 30.
  • a thread spout such as 31.
  • Each thread guide is driven along its bar by means of a small individual electric motor via a belt or a worm (not shown). The removal of the cart frees up all the space above the needle beds, which allows freely arrange the bars of the wire guides at the height and with the spacing which is most suitable for gripping and driving the wires. It is furthermore without other possibility to increase the number of bars, that is to say of thread guide and consequently the number of different threads capable of being knitted.
  • a bobbin support 31 on which are mounted six bobbins such as the bobbin 32.
  • the bobbins have not been shown in FIG. 1.
  • wire references 33, 34, 35, 36, 37, 38 are mounted wire references 33, 34, 35, 36, 37, 38.
  • the motors 12 and 15, as well as the motors of the wire guides are controlled by a programmable logic processing unit with microprocessor. Each motor is controlled individually. This means that the cam holders 4 and 5 can be momentarily desynchronized so as to be offset with respect to each other.
  • the toothed wheels 11 and 14 driving the toothed belts could be integral with a common shaft driven by a single motor.
  • the references 16, also toothed could be rigidly linked by a common axis.
  • the cam holders could be driven by other means, for example, by means of an endless screw, which could replace one of the guide bars.
  • Each bar could carry two thread guides, one thread guide on each side of the bar.
