Description
Technical field
The present invention relates to the Computerized flat knitting machine technical field, relate in particular to a kind of Computerized flat knitting machine fault detection system that can detect in real time the Computerized flat knitting machine fault.
Background technology
Computerized flat knitting machine is a kind of common Knitting Machinery, and it generally includes transmission mechanism, cloth-winding mechanism, needle selection device and needle plate mechanism, cam mechanism etc.Its triangle device of Computerized flat knitting machine is just as one group of plane cam; The stitch of knitting needle can get in the conduit of cam, moves triangle, forces knitting needle in the needle tray of needle plate, to do elevating movement clocklike; And collude the action with needle latch through pin, just can yarns be become knitted fabric.Knitting needle is in uphill process, and coil progressively withdraws from pin and colludes, and opens needle latch, and withdraws from needle latch and hang on the shank; Knitting needle is in the decline process, and pin catches on the yarn that new pad is put, and its tractive is bent to coil; Original coil of while is then deviate from pin and is colluded; New coil passes from old coil, is together in series with old coil, and the coil string that numerous knitting needles is made into connects mutually and formed knitted fabric.
Break down easily in the Computerized flat knitting machine long-term work process; Mainly be that the striker fault takes place between pin and the needle plate easily; Whether if the striker fault is when comparatively serious, even catastrophic failure such as machine can occur ruining, therefore need can break down to Computerized flat knitting machine and detect in real time.
In the prior art, a plurality of shock transducers that on needle-bar, distribute usually detect the vibration and shock signal on the needle-bar by shock transducer; After finding that certain any vibration severity exceeds standard; Can assert the striker fault has taken place, but the system that needle-bar and head constituted is a variable structure system that its needle plate of living in position is different and change; Therefore; The transfer of vibration of normal running or striker failed operation is closely related with the needle plate present position to the characteristics of signals on each sensor, and this method for diagnosing faults not the pipe die operation conditions adopt the single fixing oscillation intensity basis for estimation that exceeds standard, phenomenon appears failing to judge or judging by accident easily; If the erroneous judgement phenomenon occurs, will cause meaningless shutdown, influence the normal operating efficiency of Computerized flat knitting machine; If the phenomenon of failing to judge occurs, real striker fault is failed in time to detect, major accident further takes place easily, even catastrophic failure can occur.
Therefore, detect Computerized flat knitting machine how in real time, exactly and whether break down, become the technical barrier that those skilled in the art need to be resolved hurrily.
Summary of the invention
The purpose of this invention is to provide a kind of Computerized flat knitting machine fault detection system, whether this Computerized flat knitting machine fault diagnosis system can detect Computerized flat knitting machine in real time, exactly and break down.
To achieve these goals; The invention provides a kind of Computerized flat knitting machine fault diagnosis system; Comprise inspection controller, host computer, warning device, display unit and a plurality of checkout gear; Said checkout gear is uniformly distributed with along the length direction of needle plate and is arranged on the said needle plate, and said checkout gear is used to detect the Oscillation Amplitude of needle plate, and sends amplitude signal to said controller; Said controller receives said amplitude signal; Detected Oscillation Amplitude and preset value are compared; If said Oscillation Amplitude greater than preset value, judges then and breaks down that said controller sends fault-signal to said host computer; Said host computer receives said fault-signal, and the control Computerized flat knitting machine quits work; If said Oscillation Amplitude is greater than preset value, said controller sends alarm signal to said warning device; If said Oscillation Amplitude is greater than preset value, said controller sends the positional information of alarm signal and said checkout gear to said display unit, shows the fault occurrence positions by display unit.
Preferably, said checkout gear is an osciducer.
Preferably, said display unit is a display lamp.
Preferably, said warning device is a buzzer.
Computerized flat knitting machine fault detection system provided by the invention; Comprise inspection controller, host computer, warning device, display unit and a plurality of checkout gear; Said checkout gear is uniformly distributed with along the length direction of needle plate and is arranged on the said needle plate; Said checkout gear is used to detect the Oscillation Amplitude of needle plate, and sends amplitude signal to said controller; Said controller receives said amplitude signal; Detected Oscillation Amplitude and preset value are compared; If said Oscillation Amplitude greater than preset value, judges then and breaks down that said controller sends fault-signal to said host computer; Said host computer receives said fault-signal, and the control Computerized flat knitting machine quits work; If said Oscillation Amplitude is greater than preset value, said controller sends alarm signal to said warning device; If said Oscillation Amplitude is greater than preset value, said controller sends the positional information of alarm signal and said checkout gear to said display unit, shows the fault occurrence positions by display unit.
This Computerized flat knitting machine fault detection system; According to the vibration characteristics of needle plate physical length and each several part, be provided with a plurality of checkout gears in the length direction relevant position of needle plate, detect the Oscillation Amplitude of a plurality of positions respectively; Confirm that according to the vibration characteristics of needle plate corresponding site the Oscillation Amplitude judgment value of striker fault takes place at this position; The Oscillation Amplitude that the checkout gear actual detected arrives this judgment value is set at preset value, if can judge then that greater than this preset value the striker fault has taken place at needle plate this position; Controller can send to host computer with fault-signal, is quit work by the PC control Computerized flat knitting machine, avoids the striker fault to cause bigger fault; Simultaneously; For the ease of the maintenance personal Computerized flat knitting machine that breaks down is carried out maintenance work; Controller can send to display unit with the position signalling of fault-signal and checkout gear, shows the position of breaking down on the needle plate by display unit, so that the maintenance personal in time finds the source of trouble.
