Definitions

  • the invention relates to a flat knitting machine with a slide having a plurality of lock systems which can be used in both directions, with needles or needle pushers which can be disengaged from the lock tracks of the lock systems, with a needle selection device which has at least one needle selection point for each lock system and for each direction of travel, with electromechanically actuated drivers for the thread guides and with a control device which has a data processing unit which is coupled to a knitting program memory and a slide position transmitter and with the output side of which the needle selection device, the drivers for the thread guides and a needle offset device are connected.
  • the data processing device has at least one microprocessor which is effective as an optimization circuit for minimizing the slide stroke travel and to which several memory areas are assigned, the values taken from the machine for the slide position, the slide running direction and the position of the individual thread guides and values which can be taken from the knitting program memory for the knitting width, for the needle bed offset, for the stitch row currently to be produced, for the next stitch row and at least for the next but one stitch row.
  • the microprocessor acting as an optimization circuit in the memory areas in the data processing device is always the one for optimizing the carriage stroke important current data is made available, wherein the memory areas can advantageously be divided into higher-level and lower-level memory areas.
  • the memory areas can advantageously be divided into higher-level and lower-level memory areas.
  • a minimum of slide movement is achieved, inter alia, in that, in the case of the several lock systems, the lock systems can also be selected with regard to the lowest possible slide movement.
  • the microprocessor acting as an optimization circuit can deliver the output signals relating to the sled run, individual lock systems and individual thread guide drivers in such a way that the lock system (s) is or are selected for use, the use of which or the use of the lock system with regard to the current slide position has the least slide adjustment path during formation results from at least two successive courses.
  • output signals influencing the thread guide drivers can expediently be supplied by the microprocessor in such a way that, in the case of a slide stroke, at least one thread guide is taken into a starting position which is more favorable for the formation of a subsequent course of stitches, that is to say precautionary adjustment movements of thread guides are carried out.
  • the productivity increase achievable with a flat knitting machine designed according to the invention is remarkable.
  • the invention means that narrow knitted sections are manufactured faster than wide knitted sections during form knitting, as a result of which the productivity of flat knitting machines with short needle beds is brought into a very favorable ratio compared to the long bed flat knitting machines customary today.
  • the block diagram shows the reversible drive motor 10 for the carriage of the flat knitting machine, on which a carriage movement sensor 11 is arranged in a known manner, which supplies the signal for the data processing device, which can indicate or determine the current position of the carriage and its direction of movement.
  • the dashed double line 12 symbolizes the coupling of the carriage movement sensor 11 to the carriage drive motor 10.
  • Indicated by a dashed line of action 13 is an indirect coupling of the carriage movement sensor 11 to a knitting program memory 14 of the data processing device, in which the data important for a specific knitted fabric, its type of weave and its pattern are stored.
  • the heart of the new data processing device is an optimization circuit consisting of at least one microprocessor and effective according to a predetermined program 15.
  • the representation of key fields which are usually assigned to the knitting program memory 14 for varying data and which can also be assigned to the optimization circuit for a program variation has been left out here.
  • the optimization circuit 15 is assigned various memory areas in the data processing device, from which the optimization circuit 15 has the current data required for optimizing the carriage movement at any time. These are in particular a carriage position storage area 16, a carriage direction storage area 17, a storage area 18 for machine parameters, a knitted pattern storage area 19 and a knitted shape storage area 20.
  • the storage areas can be integrated into the microprocessor or the microprocessors of the optimization circuit 15.
  • the memory areas 16 and 17 for the slide position and the slide direction receive their current data from the slide movement sensor 11.
  • the machine parameters contained in the memory area 18 are machine-specific and relate in particular to the number of existing work systems, the arrangement of these work systems and the number and arrangement of the thread guides.
  • the memory areas 19 and 20 for the knitted pattern and the knitted shape receive their data from the knitting program memory 14. Both can be multi-layer memory areas in which the data for a plurality of stitch rows are simultaneously available to the optimization circuit 15.
  • the optimization circuit 15 supplies output signals for the carriage drive motor 10 via an amplifier stage 21.
  • the carriage movement is optimally controlled according to these signals.
  • the optimization circuit delivers 15 via an output stage circuit 22 output signals for a control of the offset device 23, which is only symbolically represented by a box, the driver 24 arranged on the slide for the individual thread guides and for the needle selection points 25 also arranged on the slide on the several work systems and thus for the control of the optimized slide movement Lock systems of the flat knitting machine.
  • the memory area 18 forms a superordinate memory area for the machine parameters.
