Definitions

  • the present invention relates to a master/slave architecture particularly for knitting machines for hosiery.
  • the electronic part is composed of a microprocessor, software and a database with which the microprocessor communicates in order to determine the active setup parameters of the machine as a function of the type of knitting to be performed on said machine.
  • the microprocessor accordingly controls needle selection and all the mechanical parts of the machine in which it is installed.
  • the aim of the present invention is to provide a master/slave architecture, particularly for knitting machines for hosiery, in which it is possible to reduce the costs of the machines without however reducing the production capacity and the quality of the product supplied by each machine.
  • an object of the present invention is to provide a master/slave architecture, particularly for knitting machines for hosiery, in which maintenance is simplified.
  • Another object of the present invention is to provide a master/slave architecture, particularly for knitting machines for hosiery, which is highly reliable, relatively easy to provide and at low costs.
  • a master/slave architecture particularly for knitting machines for hosiery, characterized in that it comprises a first knitting machine for hosiery and a second knitting machine for hosiery which are connected one another, said second machine being driven by said first machine.
  • the architecture according to the invention is a master/slave type architecture, in which two knitting machines for hosiery, of which one is designated “master” and the other one is designated “slave”, are mutually linked and the operation of the slave machine is strictly dependent on the operation of the master machine.
  • reference numeral 1 designates the portion of the block diagram related to the master machine and the reference numeral 2 designates the portion of the block diagram related to the slave machine.
  • the master machine has processing means which are conveniently constituted by a CPU 3 which is interfaced on one side with data input and display means 4 suitable to constitute an interface between an operator and the master machine (and the slave machine) and, on the other side, with interface means 5 of the master machine 1, which allow to interface the electronic part of the machine with the mechanical part.
  • processing means which are conveniently constituted by a CPU 3 which is interfaced on one side with data input and display means 4 suitable to constitute an interface between an operator and the master machine (and the slave machine) and, on the other side, with interface means 5 of the master machine 1, which allow to interface the electronic part of the machine with the mechanical part.
  • output means 6 input means 7 (sensors), means 8 for control and connection to step motors 9 of the master machine and inverter means 10 connected to the main motor 11 of the needle cylinder of the master machine 1, said main motor 11 being connected to means for detecting the position of the needle cylinder, said means being conveniently constituted by an encoder 12 whose output is fedback to the interface means 5.
  • the inverter means 10 are connected to a DAC 13 which is provided in the interface means 5.
  • the processing means 3 are conveniently connected by a serial connection 15 to an external computer or, for example, to another master machine.
  • Interface means 20 for the slave machine 2 are further provided in the master machine 1 and comprise a DAC 21 which is connected to inverter means 22.
  • the interface means 20 are further connected to means 25 for controlling step motors 26 of the slave machine 2.
  • the slave machine 2 proper therefore comprises only the main motor 23 of the machine, which is connected to the inverter means 22, which is in turn connected to an encoder 24 which feeds back its output to the interface means 20 of the slave machine 2; step motors 26 are further provided in the slave machine in order to actuate the various servomechanisms and are connected to the control means 25, which are instead accommodated in the master machine.
  • the slave machine 2 has input/output devices 27 which are connected to a display 28 and to command input means 29; said input/output devices 27 receive in input signals 30 which originate from sensors arranged on the slave machine 2 and control electric valves 35 which are connected to the output lines.
  • the input/output devices 27 are connected by means of a synchronous serial bus 31 to the interface means 20 of the slave machine 2.
  • connection between the master machine 1 and the slave machine 2 is thus entrusted to the bus 31 and to the signals in output from the step motor control means 25 and from the inverter means 22 which control the main motor 23 of the slave machine 2.
  • the main electronic part of a knitting machine for hosiery is located exclusively in the master machine 1 and the slave machine 2 is entirely dependent, as regards the electronic part, on the master machine 1.
  • the slave machine operates asynchronously with respect to the master machine and can produce either the same item being formed on the master machine or a different item, since the programming of the slave machine performed by the interface means 4 of the master machine 1 can be performed independently of the master machine 1.
  • the software of the microprocessor used in the master machine is in fact of the multitasking type, i.e., it can perform a plurality of mutually independent tasks in sequence.
  • the slave machine 2 is not provided with the corresponding electrical cabinet usually meant to contain the electronic part of a knitting machine for hosiery.
  • the architecture according to the present invention fully achieves the intended aim and objects, since it allows to drastically reduce the costs of a knitting machine for hosiery because said machine is controlled by a knitting machine for hosiery which is similar as regards the mechanical part but is provided with an electronic part which is capable of controlling the first knitting machine for hosiery as well.
  • the materials employed may be any according to requirements and to the state of the art.
